Figure 9. Wear-scar morphology and wear volume of TiN/WS2 + h-BN/NiCrBSi self-lubricating coatings with different solid-lubricant compositions. (A-E) Wear-scar morphologies and wear volumes of coatings 1-5 obtained by 3D microscopy, respectively. Coatings 1-5 were prepared with different WS2/h-BN ratios while maintaining NiCrBSi and TiN as the matrix and hard reinforcing phases. This figure is adapted from Ref.[159].
