The effect of TiN and coating parameters on the tool life extension

TiN 및 TiCN 코팅 특성이 공구수명에 미치는 영향에 대한 연구

TiN and TiCN films were deposited on the high speed steel by Cathode Arc Ion Plating(CAIP) Process to investigate the tool life extension effect. The experiment variables were bias voltage and deposit time for the TiN coating and reactive gas flow rate ($CH_4:N_2$) under fixing deposit pressure, are current, bias voltage for the TiCN coating respectively. The micro structure and mechanical properties were investigated and compared for among the coating conditions using various methods and machining practice.
