Abstract

This paper presents using Response Surface Method (RSM) to optimize average surface roughness (Ra) of titanium nitride (TiN) coating. The Cathodic Arc Physical Vapor Deposition (CAPVD) technique was used to produce the coating which is mainly used to deposit on cutting tools and molds. To optimize the Ravalue, RSM was aimed to obtain the best parameter settings. Surface profilometer was used to analyze the coating roughness for the following factors: bias voltage (Vb), nitrogen (N2) pressure (P). To conclude, when Vb = -115V and N2pressure = 9.54 × 10 E-03, the Ravalue could be optimized at 0.23μm.
