Tool Wear of Aluminum / Chromium / Tungsten/ Silicon-Based-Coated Cemented Carbide Tools in Cutting of Hardened Steel

Tadahiro Wada and Hiroyuki Hanyu
Abstract—In this study, to clarify the effectiveness of aluminum/chromium/tungsten/silicon-based coating films, hardened steel was turned with (Al53, Cr23, W14, Si10)(C, N)-coated cemented carbide tools and the tool wear was experimentally investigated. The following results were obtained: 1) The micro-hardness and the critical scratch load measured value by the scratch tester of the (Al53, Cr23, W14, Si10)(C, N)-coating film was 2990 HV0.25N and over 130 N, respectively. 2) The mean value of the friction coefficient of the (Al53, Cr23, W14, Si10)(C, N)-coating film was 0.41. 3) The wear progress of the (Al53,Cr23, W14, Si10)(C,N)-coated tool was slower than that of the (Ti, Al) N- and the (Al60, Cr25, W15) (C, N)-coated tool. 4) In the case of the feed rate of 0.1 mm/rev, the wear progress of the multilayer coated tool was almost equivalent to that of the monolayer coated tool. However, at a higher feed rate of 0.2 mm/rev, the wear progress of the multilayer coated tool was slower than that of the monolayer coated tool. The above results clarify that the new (Al60, Cr25, W15)(C, N)-coating film, has both high hardness and good adhesive strength, and can be used as a tool material in cutting hardened steel.
