TiAlN films with a TiAl interlayer were deposited on high-speed steel through a reactive sputtering process. A semi-coherent interface was observed between TiAl and TiAlN. Owing to the diffusion of nitrogen, a good bonding had formed between these layers. The TiAl interlayer substantially increased the adhesive strength of TiAlN films and, therefore, significantly affected the wear behavior. In addition, TiAlN films with a 1 μn TiAl interlayer exhibited the highest wear resistance.
