Tool wear investigations on some cutting tool materials

Tool life curves were plotted for HSS, cemented tungsten carbides, coated and cemented titanium carbides, HSS tools showed a distinct inflection coinciding with the formation ofa white diffusion layer, Crater wear propagation studies were carried out on all tools and in addition on laminated carbides. HSS, laminated carbide, and cemented titanium carbide show a tendency to form a closed crater, revealing that in these tools diffusion is a mode of wear., © 1980 by ASME.
