Description

A kind of preparation method of TiC base Steel Bond Hard Alloy complex abrasion-proof reinforcement
Technical field
The present invention relates to the preparation method of complex abrasion-proof reinforcement, be specifically related to a kind of preparation method of TiC base Steel Bond Hard Alloy complex abrasion-proof reinforcement.
Background technology
Along with the development of scientific and technological level and modern industry requires more and more higher to the wear resistance of material, the consumable accessory of the industry equipment such as electric power, cement, mine, metallurgy, coal will be subject to the wearing and tearing of the various materials such as colliery, sandstone, soil and grinding element, will consume every year a large amount of metals.All there is severe Working environment in the many fields in industrial production, require working part to possess antiwear heat resisting or wear-and corrosion-resistant over-all properties simultaneously, and the material therefore with single performance can not meet the demand of operating mode.For many years, be one of key subjects of metal-base composites research to the technical study of particle enhanced steel iron powder based composites always, also obtain some achievements.
Patent of invention (CN 101898238 A) is filled in alumina-ceramic and metal powder mixture in mould, together enter stove sintering together with mould and obtain precast body, and then precast body is put into the end face of casting mold die cavity, adopt the pouring metal melt identical with metal powder material, metal powder in precast body is fused into liquid formation casting and oozes path, forms in position particulate reinforced composite.This processing method can well merge precast body and metal, but ceramic particle is lower than molten metal density, and easily floating causes ceramic particle to be concentrated on top layer, and intensity is not high, and in addition, precast body density is not high, and precast body is easily washed out loose by liquation.Patent of invention (CN101053898A) has been introduced a kind of vacuum full mold cast-infiltration method of preparing particulate reinforced metal-based composite surface material, this castmethod is that enhanced granule is prepared into the prefabricated section adapting with the required wearing face shape of matrix material, be fixed in and need the foam materials of alloying apperance surface, then by casting technique moulding cast.Tungsten carbide particle precast body convenient formation in this castmethod, but cost is higher, is difficult to apply, and in addition, the gas that the binding agent gasification in gas and composite bed that foam produces produces makes material internal occur unavoidable gas hole defect.Chinese invention patent (CN1128297A) has been announced a kind of local composite material and manufacture method thereof, it is that ceramic particle, organic binder bond and common base steel, heat-resisting base steel or nickel base powder are mixed, be pressed into the prefabricated section of desired shape, be placed in the casting mold part of the foundry goods that needs strengthening, casting metal.The local composite material that this method is made, easily produces dreg defect, and prefabricated section is after the high temperature cast of short period, is difficult to crystallization, relative poor in conjunction with effect with the interface of substrate metal.Patent of invention (CN 101898239 B) has been announced a kind of preparation method of ceramic particle reinforcement of composite wear-resistant material, in the method, ceramic particle adopts tungsten carbide particle and in graphite jig, sinters required different shape into, reinforcement prepared by technique can produce good metallurgical binding with iron powder base matrix, in conjunction with firm, there is higher comprehensive wear resistance, but this technique because of wolfram varbide cost too high, be unsuitable for the workpiece that preparation is larger, in addition, graphite jig is also not easy to be processed into spherical structure, restricted application.Patent of invention (CN103143699A) has been announced a kind of sintering metal prefabricated component metal-ceramic prefabricated component composite strengthening wearing piece preparation method, composite prefabricated density prepared by the method is high, in casting process, be difficult for defeated and dispersed, make porcelain particle can even dispersion in metal, but blank moulding more complicated in the method, precast body easily produces tiny crack in casting cycle, has potential safety hazard, and ceramic particle also easily comes off after may wear to a certain degree.
Summary of the invention
