In carbide cermet coatings, such as WC–Co–Cr, the surface roughness of the sprayed workpiece is much more than the acceptable values for various industrial demands. Thus, the surface of the carbide cermet coatings is to be ground appropriately to obtain suitable surface finish. However, the grinding may change the properties of coating. In this study, effects of the grinding process on the porosity content, residual stress, microhardness, and adhesion and cohesion strength of the high-velocity oxy-fuel WC–10Co–4Cr coatings are investigated. For this purpose, the grinding experiments have been performed on a surface grinder using a diamond wheel (resin bond) under different grinding parameters, such as table feed rate, cutting speed, and depth of cut. The investigations of residual stress state and adhesion properties were carried out using the X-ray diffraction and interfacial indentation test methods, respectively. The results indicated that the coating's porosity content increased after grinding due to the mechanical loading of coating by diamond grits of the grinding wheel. On the other hand, adhesion and cohesion strength and microhardness of the coating were improved after grinding. This can be interpreted by the residual stress state of the coating samples.
