Paper Title:
Performance of Titanium-Tungsten-Silicon-Aluminum Based Coated Cutting Tools
  Abstract

In order to determine an effective coating film for cutting carbon steels with a coated cemented carbide tool, tool wear was experimentally investigated. Low carbon steel (AISI 5120H steel) was turned with four kinds of physical vapor deposition (PVD) coated cemented carbide tools. The coating films used were TiN coating film and three kinds of titanium-tungsten-silicon-aluminum based coating films, namely (Ti,W,Si,Al)N, (Ti,W,Si,Al)C and (Ti,W,Si,Al)(C,N) coating film. (Ti,W,Si,Al)N, (Ti,W,Si,Al)C or (Ti,W,Si,Al)(C,N) is a new type of coating film. The following results were obtained: (1) The critical load of three kinds of titanium-tungsten-silicon-aluminum based coating films was higher than that of TiN coating film. (2) The hardness of three kinds of titanium-tungsten-silicon-aluminum based coating films was higher than that of TiN coating film. (3) In cutting low carbon steel, the wear progress of three kinds of titanium-tungsten-silicon-aluminum based coating film tools was slower than that of the TiN coated tool. (4) In the three kinds of titanium-tungsten-silicon-aluminum based coating films, the wear progress of the (Ti,W,Si,Al)N coated tool was the slowest.
