Because conventional rays method blade thickness measurement technology described in the utility model does not use at present at home, market outlook are considerable.
The content augmentation explanation that present embodiment is relevant:
One, designing requirement: according to the designing requirement of the Russian side, ray method is adopted in the measurement of 7 wall thickness of high vortex blade leading edge δ, and the minimum wall thickness (MINI W.) value of its measuring point and permission is seen Fig. 4,5, table 1.
The minimum wall thickness (MINI W.) value of the position of each cross section point of table 1 and permission
| The cross section numbering | Apart from the listrium planar dimension | The drawing wall thickness | The minimum wall thickness that allows |
| A1-A1 | 66mm | 0.55-0.90 | 0.50 |
| A2-A2 | 55mm | 0.64-0.99 | 0.50 |
| A3-A3 | 44mm | 0.73-1.08 | 0.65 |

Two, the characteristics of part:
High-pressure turbine blade inner chamber complexity is netted hollow-core construction, is the hot investment casting high-temperature alloy blades.Because plasticity completely lost when blade can cause being out of shape with the further alloying of wrought superalloy, its development potentiality exhausts, so the cast superalloy heat resistance obviously is better than wrought superalloy.Compare with wrought superalloy, cast superalloy has higher heat resistance, higher stock utilization, and along with the development of foundry engieering, cast superalloy is used on modern aviation gas engine widely.
Various countries, the world today all have the novel aviation gas engine of the air cooling turbo blade of labyrinth in development, and adopt the blade of backflow and air film cooling AS, can only be the hot investment casting high-temperature alloy blades.To hollow blade, its inner chamber cooling technology is cooled to efficient compound cooling from convection current from initial casting solid vane, and the profile and the inner-cavity structure of blade also become increasingly complex.The appearance of hollow air cooling blade had both alleviated leaf weight, had improved the warm ability of holding of blade again.
High-pressure turbine blade is the strength member on the engine, and the attenuate of the wall thickness of blade can impact the use of blade, and then influences the safety of aircraft, therefore, no matter be that blade during the blade newly developed also is to use all needs to carry out the measurement of blade wall thickness.
Three, test is prepared
1, material
Major ingredient: blade, detect frock, X-ray film, lead intensifying screen, show, photographic fixing cover medicine, ruler;
Auxiliary material: black paper, adhesive plaster, lamp box, plumbous font size, stereotype;
2, equipment: X-ray production apparatus, detection frock, scale magnifier, viewbox.
3, ray detection principle and technology:
1) ray detection principle: ray detection technical basis ray and matter interaction and its attenuation law, realize detection to defective in the workpiece or other characteristic.
2) thickness measurement with ray method: the method for carrying out wall-thickness measurement with radiography can be divided into two big classes: direct method and indirect method.
Direct method is to we carry out radiography at institute's interesting areas on the object, then a kind of method of directly carrying out thickness measure from the radiographic X egative film.The object that the most suitable employing is directly measured is that tested position can allow the object of the fine applying of film, can avoid the distortion of image like this.Indirect method is being the basis by the thickness of radiography material and the pass that obtains between the blackness of egative film, draws the relation curve (typical curve) of photographic density and thickness, then according to blackness value, finds the one-tenth-value thickness 1/10 of correspondence from typical curve.If the direct measuring of thickness can not adopt, should consider indirect measuring method.
According to the characteristics of blade leading edge, can adopt the direct method of measurement.Because the leading edge of blade and film can well be fitted, carry out radiography by leading edge, so that can directly on egative film, measure to blade.The process of measuring can be finished by the accepted scale magnifier.
3) process program: adopt the X ray method that the blade wall thickness is measured, domestic also not having ripe experience can be used for reference at present, in order to guarantee the reliability of ray detection method thickness measuring, need to select suitable process and technological parameter by a large amount of test repeatedly and contrast.
Frock making: when carrying out the radiography detection, at first will consider the transillumination angle of ray.See Fig. 4,5.Beam should because the special construction of blade wants each transillumination and can both guarantee this angle, must design frock clamp perpendicular to by the transillumination position, guarantees the accuracy and the repeatability of transillumination angle.In order to guarantee that measurement point truly shows on egative film, when this frock of design, need the position of measuring is considered in the lump, telltale mark is projected on the egative film together with blade.After frock making is finished, measure evaluation, determine the requirement that angle and telltale mark satisfy drawing of putting of blade.The frock of making is seen Fig. 1,2,3.
Magnifier: adopt the magnifier of band rule owing in process of the test,, select the higher scale magnifier of precision as far as possible in order to verify the feasibility of X ray detection method to the blade thickness measuring, with the size that guarantees to measure more near actual value.The selection of scale magnifier, first will consider the precision of scale, but also will consider its operability simultaneously.Because precision is high more, enlargement factor is high more, and when precision reaches 0.05, its minimum enlargement factor will reach 30 times, make the obscure boundary of film image clear after the amplification, can't locate.Simultaneously, the effective diameter and the field of view of high more its magnifier of precision, enlargement factor also reduce thereupon, are difficult for observing, and actual measurement is difficulty.We select two sections of magnifieres to test, and the technical indicator of magnifier sees table 2 for details.
Table 2
By a large amount of tests, the magnifier of 1983-10X model can meet the demands, and the visual field and effective diameter are bigger, is easy to observe, and measures more conveniently relatively, has operability.The magnifier of 2037-30X model, though precision is higher, its visual field and effective diameter are little, are not easy to observe.
Pilot blade quantity: totally 55.
4) determining of X ray transillumination technology:
The selection of radiography technology must strict control influence the factor of image so that obtain optimum.These factors comprise: geometrical factor, scattered ray and owing to relate to fuzzy that very thin object boundary causes in measuring.
Adopt the direct method of measurement, it is wanted fine applying by transillumination position and film, can avoid the distortion of image like this.Film should adopt fine grained film to improve the contrast of image.
In order to improve accuracy to high vortex blade leading edge wall thickness measuring, when choosing transillumination technology, mainly should consider the indistinctness of image, because, the indistinctness of image has determined discernible details size on perpendicular to the sensitivity of film direction, i.e. the degree of image boundary expansion.To industrial radiography, the main cause that produces indistinctness is geometric unsharpness and film inherent unsharpness.Geometric unsharpness and ray source focus size, focal length, thickness of workpiece are relevant.Focal spot size is more little, focal length is big more, the more little then geometric unsharpness of thickness of workpiece is also more little.The film inherent unsharpness is owing to incide the ray of film, and the scattering of the electronic secondary that has excited in emulsion produces.The film inherent unsharpness is decided by the energy of ray, and energy is big more, and the inherent unsharpness of film is big more.So, according to mentioned above principle, in order to obtain less indistinctness, make image boundary more clear, more trend towards actual value, to the selection principle of transillumination technology: lower voltage, bigger focal length.By test repeatedly, process and technological parameter are determined as follows:
Transillumination is arranged: in process of the test, only made a frock, so once can only 5 blades of transillumination.In the production application in later stage, because effectively can the while symmetry put 2 frocks in the transillumination district, but promptly each 10 blades of transillumination.Blade when putting, its tested position should with the fine applying of film, can avoid the distortion of image like this, make the data of measurement more accurate.By the examination transillumination to blade, the frock of making can meet the demands substantially, but some place also comes with some shortcomings by using, and the frock size is less than normal, and egative film is put a bit difficulty, requires further improvement.Fig. 4 is the transillumination synoptic diagram of blade when carrying out the X ray detection, and Fig. 5 is the transillumination arrangenent diagram.
Technological parameter: the darkroom is handled and is preferably adopted technology for automatically treating, can keep constant relatively development effect, impels the standardization of X ray transillumination condition, standardization, improves the quality of image and work efficiency.By repetition test, select following transmitting illumination parameter.See Table 3.

Carry out transillumination according to above-mentioned technological parameter, photographic density is controlled between the 1.7-1.8 basically.(3) measurement of blade: will have 5 points to need to measure at leading edge on each blade, the accepted scale magnifier is measured during measurement, in measuring process, the datum line in the scale magnifier should be overlapped with any edge line of measuring point, then reading numerical values.Fig. 6 is seen in concrete measuring method and measuring point.
Four, result: adopted X ray and ultrasonic method to carry out wall thickness measuring respectively to 55 blades, and from 3 blades of arbitrary extracting wherein, dissect according to 5 sectional positions that design drawing requires, dissecing the back entrusts measurement centre to measure the measured value of blade δ 7 place's wall thickness, this value and above-mentioned two kinds of methods compare, and see Table 4.
Attention: on behalf of X-ray measurement, the font of band underscore do not conform to lattice point; On behalf of ultrasonic measurement, the font in the wave line style square frame do not conform to lattice point.Font representative metering actual measurement in the rectangular box does not conform to lattice point.
His-and-hers watches 4 measurement data are drawn out the broken line graph of three kinds of measuring method rays, ultrasonic, metering (measured value), can the Analysis of X ray from the broken line graph, the comparable situation of ultrasonic and measured value.See Fig. 7,8,9.
The wall thickness value that table 4X ray and ultrasonic two kinds of methods are measured and the metering measured value table of comparisons
Discussion of results and analysis:
55 blades have been measured altogether, 275 points.Wherein there are 23 points defective, have 30 points defective with the ultrasonic method measurement with the ray method measurement.The data that nearly about 40% point is measured with these two kinds of methods are identical; The data that two kinds of methods of point about 60% are measured differ in 0～0.15 scope.
Table 4 is to extract 3 blades from 55 blades at random out, dissects according to 5 cross sections, send measurement centre to measure the measured value of each cross section point after dissecing.The value of these data and ray, ultrasonic measurement compares, and can find out clearly by the broken line graph of drawing out, and the data of X-ray measurement and the measured value of metering are more approaching.
Ray detection guarantees the measuring point by frock, and after the transillumination frock was determined, the position of each transillumination was certain, and the position of measurement is unique; And ultrasonic thickness measurement, measurement be a scope, near measurement point, get minimum value, so survey the wall thickness of 7 of blade leading edge δ, will be subjected to the influence of the radius-of-curvature in cross section with ultrasonic method.
Many from the processing step of ray method own, at first need technological preparation, transillumination, egative film processing, location, wall thickness measuring etc., also have certain material consumption such as costs such as film, liquid medicine higher relatively simultaneously.So measure the blade wall thickness with ray detection method, detection efficiency is low, the cost height.
Five, conclusion: utilizing the X ray method to measure the wall thickness of 7 of high vortex blade δ, is feasible.Through dissecting error at 0.01-0.05mm, the repairing that its precision can satisfy certain machine require and repeatability better.For improving the detection efficiency of thickness measurement with ray, next step will be carried out digitizing and detect research, can consider to measure automatically after the x-ray film that transillumination is good converts digital picture to.
