摘要

Nanostructured ceramic coatings has excellent properties, their industrial application depends not only on their fabrication but also on their precision grinding technology, so it is necessary to study the material removal mechanism in grinding of nanostructured ceramic coatings. This paper presents experimental results on how the grinding processes parameters affect the grinding force ratio and specific grinding energy as well as surface roughness in precision surface grinding of nanostructured WC/12Co (n-WC/12Co) coating and also presents SEM observations of surface and subsurface of n-WC/12Co coating ground under different grinding conditions. Furthermore this paper discusses the material removal mechanism in grinding of n-WC/12Co coatings and gives priority to inelastic deformation instead of brittle fracture, which provides theoretical basis for the precision grinding of nanostructured ceramic coating.
