Abstract : Coating properties of the (Al, Cr, W)-target are improved by adding tungsten to the (Al, Cr) target. Therefore, in
this study, to clarify of the effectiveness of the (Al,Cr,W) -coating film for cutting alloy steel, the tool wear was experimentally
investigated. The following results were obtained: (1) The wear progress of coated cemented carbide tool deposited using the
(Al,Cr,W)-target was slower than that of the coated cemented carbide tool deposited using the (Al,Cr)-target. (2) The wear
progress of the (Al64, Cr28,W8)N-coated tool was slower than that of the (Al60, Cr25,W15)N-coated tool. (3) In the case of
the coated cemented carbide tool deposited using the (Al64,Cr28,W8)-target, although the adhesiveness of the
(Al64,Cr28,W8)(C,N)-coated tool by adding carbon to the (Al64,Cr28,W8)N-coating film became higher, the wear progress
of the (Al64,Cr28,W8)(C,N)-coated tool became faster than that of the (Al64,Cr28,W8)N-coated tool. (4) As compared to the
wear progress of the (Al64,Cr28,W8)C-coated and that of the (Al64,Cr28,W8)(C,N)-coated tool, the wear progress of the
(Al64,Cr28,W8)C coated tool was slightly slower. For this reason, it was considered that although the micro-hardness of the
(Al64,Cr28,W8)C-coating film was lower than that of the (Al64,Cr28,W8)(C,N)-coating film, the average value of the friction
coefficient of the (Al64, Cr28,W8)N coating film, 0.26, was about half of that of the (Al64, Cr28,W8)(C,N) coating film, 0.53.
Index Terms - (Al,Cr,W)-based-coating film, cutting, tool wear, alloy steel.
