Abstract
High hardness. mechanical strength, heat resistance and wear resistance of M3/2 high speed steel (HSS) make it an attractive material for manufacture of Valve train components [1,2,3]. In this application, the material must exhibit oxidation resistance, high hot strength and hardness, and superior wear resistance. Metal matrix composites were produced by powder metallurgy techniques and were composed by a infiltration high speed steel based material into which hard abrasive wear resistant carbide particles were incorporated at the powder compaction stale. Since technological and economical considerations are equally important. infiltration of high-speed steel skeleton with liquid cooper has proved to be a suitable technique whereby fully dense material is produced at low cost [1,2]. Infiltration is a process that has been practiced for many years. Infiltration is basically defined as "a process of filling the pores of a sintered or unsintered compact with a metal or alloy of a lower melting point" [4]. In the particular case of copper infiltrated iron and steel compacts, the base iron matrix. or skeleton, is heated in contact with the copper alloy to a temperature above the melting point of the copper, normally within the range of 1095 degrees to 1150 degrees C. Attempts have been made to describe the influence of the production process parameters and alloying additives. such as graphite and electrolytic cooper, on the microstructure and mechanical properties of copper infiltrated KISS based composites. The compositions of powder mixtures are 100% M3/2, M3/2 + 7.5%Cu, M3/2 + 0.3%C.
