The present invention includes two spray guns and their motion controller, substrate elevator mechanism and forced cooling mechanism. It can be used to produce very large deposited pipe blank and ingot blank without size limitation principally. The present invention has also advantages of high cooling speed, no component segregation, fine and homogeneous crystallite, low oxygen content, etc. It is incomparable, especialy in preparing grain-reinforced metal-base composite material.
Description
The present invention relates to a kind of multilayer spraying deposition method and equipment for preparing large deposited blank.
Spray deposition technique is that the Singer A by Britain teaches in the seventies and proposes the earliest, principle is: molten metal or alloy are atomized in inert atmosphere forms particle jetting stream, inject directly on the matrix of water-cooled, through bump, coalescent, solidify and form settling.Spray deposition technique is a kind of novel blank-making method, is widely used in various alloys of preparation and matrix material pipe thereof, slab, ingot blank etc.In recent years, though spray deposition technique has obtained fast development, all be the principle that adopts Singer professor A to propose in essence." Arms Material scientific and engineering " the 17th volume, the 2nd phase (1994) has been introduced the equipment and the technological process of this technology, and this technology has the characteristics of powder metallurgy and rapid solidification concurrently, has overcome the shortcoming of the component segregation in the casting metallurgy, the grain structure of blank is tiny, and oxygen level is low.Jet deposition equipment as shown in Figure 1, 2, comprising crucible 1, nozzle 2, deposition matrix 3, spray chamber 4, vapor pipe 5, transmission mechanism 6, interior device for cooling 7 with shake nozzle 10.The common feature of equipment is that deposit preform forms through the matrix deposition by jetting fluid grain stream is disposable, and the deficiency of existence is that sedimental cooling rate generally has only 10
1～10
2K/s, and be difficult to prepare large thick-wall pipe and the very big ingot blank of diameter, if solve problem,, often cause shortcomings such as sedimental component segregation, grain structure is thick, the pyrocondensation hole defect is many then because setting rate is not high enough by improving injection density.
The purpose of this invention is to provide a kind of method and apparatus that can prepare the multi-layer spray deposition of large deposited blank.
The present invention---a kind of multilayer spraying deposition method and equipment for preparing large deposited blank, when preparing large jet deposited base, the spray gun of atomization metal melt is done linear reciprocating motion along the deposition matrix, because matrix also can move reciprocatingly, longer in the timed interval that the back surface sediments of same position reaches last surface sediments, form the sputter border in the deposit preform easily, influence the quality of deposit preform.In order to eliminate this sputter border, realize optimum deposition condition, processing parameter is selected as follows in process of production: nozzle diameter is 2.5～5mm, the round frequency of spray gun is 1/10～1/30Hz, jetting height is 100～300mm, and the melt overheat temperature is 100～300 ℃, and atomization air pressure is 0.8～1.5MPa, deposition matrix rising or falling speed is 1～20mm/min, and the matrix rotational frequency is 1～1/6Hz.Composition by the control metal melt can prepare gradient material, adopts the spray gun of special construction can also prepare large jet deposited matrix material heavy wall pipe and ingot blank.
For realizing above-mentioned spray-deposition method, jet deposition device structure of the present invention such as Fig. 3, shown in Figure 4.
When the large-scale pipe of preparation, adopt equipment shown in Figure 3, comprise crucible 1, spray gun 2, matrix 3, spray chamber 4, the present invention also comprises two spray gun motion control devices, matrix hoisting appliance, the sedimental strong device for cooling of cooling.Crucible 1, spray gun 2 are fixed on the motion guide plate 11 jointly, and guide plate 11 is as the upper cover plate of spray chamber 4, and motion controller 15 acts on the guide plate 11, controls its travel direction, speed speed and movement travel.Deposition matrix hoisting appliance is made up of one group of gear drive and lifting controller 12, the speed in the time of can controlling the height of matrix 3 liftings and lifting.Strong device for cooling comprises refrigerant supply 13, switch-valve and conduit, its effect is: after the metallic particles injection stream deposits on the matrix 3, open in the matrix below, face the coolant duct jet orifice 14 of deposition matrix immediately to the settling ejected coolant, make it external cooling, heat-eliminating medium is liquid nitrogen or rare gas element.According to the difference that the preparation blank requires, the movement locus of two gun systems and the sedimental type of cooling also can be adjusted.By jointly controlling of lifting controller 12 and motion controller 15, can adjust the physical dimension of pipe, the thickness of pipe can be unrestricted in principle.
When the large-scale ingot blank of preparation, adopt equipment shown in Figure 4.Comprise crucible 1, spray gun 2, matrix 3, oblique spraying mechanism, matrix hoisting appliance, the present invention also comprises oblique spray motion control device, the sedimental strong device for cooling of cooling of control spray gun 2 and guide plate motion 11 thereof.Tiltedly the spray motion control device is made up of crucible 1, spray gun 2, motion guide plate 11 and motion controller 15, guide plate 11 is as the upper cover plate of spray chamber 4, motion by motion controller 15 control guide plates 11, travel direction, speed and stroke are adjustable, can control the diameter of ingot blank thus, the diameter of ingot blank is unrestricted in principle.The angle of motion guide plate 11 and horizontal plane can be adjusted between 10 °～50 °.Strong device for cooling is made up of refrigeration system 16 and condenser 17, and the temperature of condenser 17 is by refrigeration system 16 controls.Height by hoisting appliance 12 control ingot blanks.
