摘要：

Nanocomposite coatings of CrN-WS(2) were prepared at different Cr contents (approximately 8-39 at%) using an unbalanced magnetron sputtering system. Structural changes in CrN-WS(2) coatings with variation in Cr content were studied using X-ray diffraction. CrN-WS(2) coatings displayed a dense, compact microstructure with reduced columnar growth in the field emission scanning electron microscopy data. Nanoindentation and nanoscratch data showed that CrN-WS(2) coatings exhibited improved mechanical and adhesive properties, respectively. Micro-tribometer tests at a load of 2 N indicated that CrN-WS2 coatings prepared at 31 at% Cr exhibited a stable friction coefficient of 0.20-0.24 even after 8 h. (C) 2011 Elsevier Ltd.
