抄録

Mechanically alloyed ceramic particles (Si, AlN, Al₂O₃ or SiC; 0.4-1μm in diameter; 15vol%)/aluminum composite were machined by dry turning using sintered tungsten-carbide tools and sintered diamond ones with different contents of Co as a binder. In both kinds of tools, the tool wear was uniquely related to the cutting distance, and its amount did not depend on the content of Co. Despite such an apparent similarity in the wear behavior for both kinds of tools, the amount of wear in the latter tools was much smaller than that in the former ones. The main factor determining the amount of tool wear was not the macroscopic (average) hardness of tools and alloys, but the hardness of ceramic particles involved in them; tool wear and hence cutting resistance decrease remarkably in case that the particle hardness in tools exceeds that in work materials.
