Abstract—In this study, a carbonitride coating film was
deposited on a cemented carbide ISO K10 using three different
Al-Cr-W-Si targets. The coating film structure consists of
mono-layer film and multi-layer films. The hardened steel
ASTM D2 was cut with five types of coated cemented carbide
tools. The tool wear of the coated tools was experimentally
investigated. The following results were obtained: (1)
Comparing the wear progress of the
(Al53,Cr23,W14,Si10)(C,N)- and
(Al58,Cr25,W7,Si10)(C,N)-coated tool, the wear progress of
the (Al58,Cr25,W7,Si10)(C,N)-coated tool is slightly slower
than that of the (Al53,Cr23,W14,Si10)(C,N)-coated tool. (2)
Comparing the wear progress of the
(Al60,Cr25,W15)(C,N)/(Al53,Cr23,W14,Si10)(C,N)- and the
(Al53,Cr23,W14,Si10)(C,N)/(Al58,Cr25,W7,Si10)(C,N)-coated
tool, the wear progress of the
(Al53,Cr23,W14,Si10)(C,N)/(Al58,Cr25,W7,Si10)(C,N)-coated
tool is slightly slower than that of the
(Al60,Cr25,W15)(C,N)/(Al53,Cr23,W14,Si10)(C,N)-coated
tool.
