Background technology
Carbide alloy is owing to having high rigidity, a series of premium properties such as wear-resisting, heat-resisting, corrosion-resistant, be widely used in industrial circle, as made the cutter making all size shape, cutlery, feeler gauge, or be made into various diel, particularly day by day ripe in high speed stamping field, but carbide alloy manufactures high, fragility is comparatively large, should not be used for the vulnerable part that the power of being hit is larger.In addition, along with the develop rapidly of China's industry, the range of application of carbide alloy and consumption are also increasing year by year, and the stub bar of the various sintered-carbide tool scrapped as drill bit, milling cutter, reamer, lathe tool etc. and when preparing instrument is also corresponding to be increased; There are the serious problems such as energy consumption is large, equipment is complicated, environmental pollution because current carbide alloy reclaims reproduction process, therefore scrap carbide alloy and be not fully effectively used; And the carbide alloy that these are scrapped can be made into the wild phase needed for wearing composite material through simple cutting processing.Therefore, the carbide alloy utilizing recovery to scrap prepares wearing composite material as wild phase, can be national economize energy, protection of the environment on the one hand, also greatly can reduce the manufacturing cost of composite on the other hand.
By compound technology of preparing by ferrous alloy compositely preparing surface-layer wearing composite material high, cheap to carbide alloy and good toughness, intensity, it has higher intensity and good toughness while obtaining the high rigidity of carbide alloy, high-wearing feature, and expensive carbide alloy can be saved, reduce the cost of wear part, expand the range of application of carbide alloy.
Although some carbide alloy/iron base composite material product has started application in the industry, and achieves certain economic benefit, limit its scope of application owing to still there is following problem.(1) because carbide alloy and ferrous alloy line (swollen) swollen coefficient differ greatly, therefore larger residual stress can be produced at interface, in heat treatment subsequently and use procedure, workpiece easily ftractures, particularly along with the increase of carbide alloy volume integral number, residual stress is corresponding increase also, causes composite often to ftracture in preparation, heat treatment and use procedure, more cannot prepare the high abrasion composite with high-volume fractional (being greater than 30%) wild phase.(2) in preparation process, due to the fusing of interface carbide alloy and the phase counterdiffusion of element, can be formed containing large block fragility η phase (Fe3W3C, Co3W3C, or (Fe, Co) 3W3C etc.) region, this region is usually the crack initiation source that cracking occurs workpiece.Therefore, prepare good toughness, prevent the design of the hard alloy/high-chromium alloy-based wear-resistant composite material ftractureed and technology of preparing to be badly in need of improving.
