Outline of Final Research Achievements

Cemented carbide ISO K10 was PVD coated using several different (Al, Cr, W, Si) targets. N2 and (N2, CH4) gases were used as reaction gases. Also, the bias voltage was varied. First, the coating properties were investigated. In cut ASTM D2 hardened steel (60HRC), tool wear was investigated. Based on these results, coating films for cutting tool with excellent adhesion and wear resistance were developed.
