Abstract
The utility model provides a metal analysis test block for precipitated phase detects, characterized by: the metal analysis test block is column that has two relative terminal surfaces or the square that has two opposite flanks form, there is the one end welding of the copper line that insulation support was wrapping up in the middle of a terminal surface of metal analysis test block or a side and both ends are exposed, the metal analysis test block except that relative terminal surface or opposite flank all the surface and the copper line has sealing material with the exposed one end parcel of metal analysis test block welded, the outer parcel of sealing material have the plastic tubing. The utility model discloses can accomplish the test analytique of precipitated phase easy and simple to handlely, and simple structure, production is easy, low cost.
Description
Technical field
The utility model relates to a kind of metal material and detects test block, especially relates to a kind of metal analysis test block detected for precipitated phase adopting the specific precipitated phase of electrochemical method exposing metal.
Background technology
The definition of precipitated phase: in material with discontinuous state be distributed in body mutually in and the phase of other phases can not be surrounded by wherein, be referred to as precipitated phase.Metal material carry out fabric analysis particularly precipitated phase analyze time, sample normally grinds by existing technological means, utilize specific chemical reagent corrosion sample after polishing, because the energy of crystal boundary, precipitated phase is different, the reaction velocity with corrosive liquid is variant thus can examine under a microscope different patterns.But all precipitated phases are all classified as a class by this method in actual use further can not distinguish observation, therefore there is its limitation when doing precipitated phase and analyzing, accurately can not analyze the pattern quantity of variety classes precipitated phase.
Utility model content
Technical problem to be solved in the utility model, is just to provide a kind of metal analysis test block detected for precipitated phase designed on the basis of electrochemical method, can completes the analytical test of precipitated phase easy and simple to handlely.
Solve the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of metal analysis test block detected for precipitated phase, it is characterized in that: described metal analysis test block is have the column of two opposing end surfaces or have the square of two opposite flanks, the one end of the copper cash that one end face of described metal analysis test block or a side have insulating sleeve to be wrapped in an exposed centre, two ends is welded, exposed one end that all surface of described metal analysis test block except opposing end surface or opposite flank and described copper cash weld with metal analysis test block is enclosed with encapsulant, and described encapsulant is wrapped with plastic tube.
One end of described copper cash and the welding manner of described metal analysis test block are soldering.
Described encapsulant is AB glue.
Described insulating sleeve is gum sleeve.
Compared with prior art, the utility model tool has the following advantages:
(1) analytical test of precipitated phase can be completed easy and simple to handlely;
(2) structure is simple, produces easily, with low cost.
Accompanying drawing explanation
Fig. 1 is structure cross-sectional schematic of the present utility model.
In figure: 1-metal analysis test block, 2-copper cash, 3-plastic tube, 4-encapsulant.
Embodiment
Below in conjunction with accompanying drawing, by embodiment, the utility model is described in further detail.
As shown in Figure 1, a kind of metal analysis test block detected for precipitated phase, metal analysis test block 1 is for having the square of two opposite flanks, the one end of the copper cash 2 that one side of metal analysis test block 1 is wrapped in an exposed middle rubber sleeve pipe in two ends is welded, and wherein one end of copper cash 2 and the welding manner of described metal analysis test block 1 are soldering; Exposed one end that all surface of metal analysis test block 1 except opposite flank and described copper cash 2 weld with metal analysis test block is enclosed with encapsulant 4, and encapsulant is AB glue, and encapsulant 4 is wrapped with plastic tube 3.
This test block, when testing, first waits for the air-dry and whole test block of encapsulant after fixing with the opposite flank that abrasive paper for metallograph grinds, test block is analyzed in polishing metal; Polished metal analysis test block can carry out electrolysis under electrochemical method, and the other end of copper wire is connected to power anode, and the precipitated phase tested as required selects suitable electrolytic solution to be negative electrode, according to the different choice decomposition voltage of material and precipitated phase; After above-mentioned conditional operation a period of time, the matrix of metal analysis test block surface and other precipitated phases can be dissolved in electrolytic solution, and the precipitated phase needed is retained on sample, take out sample clean up cut off copper wire can observation analysis precipitated phase.
In practical application, such as: the feature using the utility model to analyze σ phase in Super304H steel, in Super304H steel, precipitated phase has M23C6 carbonide, MX carbonitride equal with σ, and analyzing separately σ phase time needs other phases and matrix to remove.Adopt scheme of the present utility model, first the test block of Linear cut Super304H steel is of a size of 10 × 10 × 5mm, diameter is selected to be that the plastic tube of 15mm height 15mm is as wrappage, select common AB glue as encapsulant, the brass wire diameter selected is that each exposed 4mm intermediate portion, 2mm two ends is wrapped up by gum sleeve.First one end of copper wire is soldered on a side of examination Super304H steel test block, tin welding spot requires firm, the test block of Super304H steel is steadily placed in horizontal table top together with copper wire, first be inserted in plastic tube, AB glue is poured into again in plastic tube, AB glue wraps exposed one end of the test block of super304 steel and the copper cash of soldering on test block one side and leaves an exposed end at plastic tube, super304 steel test block opposite flank, grind the opposite flank of Super304H steel test block with abrasive paper for metallograph after AB glue is air-dry, use this side of polishing cloth polishing Super304H steel test block subsequently.Tartrate reagent electrolysis 1min is used in Super304H steel test block after polishing under the continuous current potentiometer of 0.6A.Take out the test block of Super304H steel after electrolysis completes and remove unnecessary copper wire, the σ phase then under scanning electron microscope in observation analysis Super304H steel.
