摘要：

This study is aimed at experimentally investigating the effect of microgrinding process on the surface finish, subsurface damage and residual stresses of thermally sprayed nanostructured WC/12Co (n-WC/12Co) and Al2O3/13TiO(2) (n-Al2O3/13TiO(2)) coatings. The material removal mechanisms are discussed. Surface textures are measured with stylus profilometry, scanning electronic microscopy (SEM) and atomic force microscopy (AFM), and analyzed using conventional methods and scale-sensitive fractal analysis. Residual stresses are measured with glancing incident X-ray diffraction (GIXD) technique that is capable of providing the depth profiles of residual stresses. Investigated is also grinding damage to the coatings.
