Abstract

A composite TiSiN/Ag/TiSiN multilayer coating was deposited on a Ti6Al4V substrate by multi-arc ion plating system. The coating had a special structure with a TiN buffer layer, TiSiN/Ag multilayers that possess alternating TiSiN (45 nm) and Ag (12 nm) layers, and TiSiN coating interlayers of 120 nm thickness for a total thickness of 1.7 μm. The TiSiN layers had a nanocrystalline/amorphous microstructure of nc-TiN, nc-Ag and amorphous Si₃N₄, with amorphous Si₃N₄ present around nanocrystal TiN and Ag boundaries, and Ag layers consisting of ductile nanocrystal silver. We have shown that this design of the composite TiSiN/Ag/TiSiN multilayer coating can effectively hinder crack propagation and increase fracture resistance of the coating.
