Abstract

Abstract A dc magnetron sputter (dcMS) deposition and a pulsed dcMS deposition methods were used respectively to deposit TiN and W 2 N coatings in a mixture gas of Ar and N 2 . Single layer TiN and W 2 N were first obtained to determine the deposition condition for the multilayers. TiN/W 2 N multilayers were deposited and the effects of the substrate rotation speed and the N 2 /Ar concentration on microstructure, hardness, and the corrosion property have been examined. It was observed that the multilayer TiN/W 2 N adheres well onto the substrate. In addition, the hardness and the anti-corrosion property of the multilayer are also better than that of the single-layer coatings.
