Abstract


For hardening parts working under conditions of high temperature wear, composite materials (CM) based on refractory solid particles are widely used. Carbides of IV-VI group A transition metals determining physics of high-temperature wear are used as particulates. Therefore, it is ecessary to explore a complex of CM physico-chemical properties that satisfy the conditions of high temperature wear, name, thermal and power characteristics of carbides; conditions weakening metal carbides at elevated temperatures and limiting IV–VI group carbides solubility in metal-bundles. Using the methods of laser interferometry, X-ray, dislocation and energy analyses the most effective ways to improve the durability of parts haedened wth new CMs based on sintered hard alloys in high temperature wear are studied and developeed. For this purpose the TiC- based TN 20 sintered carbide having a ring structure prevents the formation of complex alloyed phases on the solid particle - matrix boundary is used. Due to the minimal solubility of the TN 20 sintered carbide in the matrix on the solid particle - matrix boundary surface, highly alloyed structural phases causing embrittlement and resulting in increased residual thermal deformations are almost not formed. As a consequence, new СMs based on sintered TN 20 particulates can be recommended for hardening parts working under conditions of high temperature abrasive wear.
