Abstract  

In-depth study of the damage mechanism of hard and brittle 6H-SiC materials during the grinding process with nano-particles is of great significance to improving the surface quality of 6H-SiC components. In the article, the surface deformation behavior of the bulk 6H-SiC materials during grinding with nano-diamond abrasives was simulated by means of molecular dynamics simulation, while revealing the subsurface damage mechanism and considering the effects of abrasive grain size and grinding speed. The results show that when the abrasive grain size is larger than 4.9 nm, as the grinding speed increases, the material removal first increases and then decreases, and the removal of 6H-SiC material is primarily based on adhesion. By a constant grinding speed, as the abrasive grain size increases, the damage depth, subsurface temperature, and lattice defect degree of the 6H-SiC workpiece first decrease and then increase. Additionally, the grinding speed has much significant impact on the subsurface damage depth and grinding force of the workpiece, for the abrasive grain size is 5.4 nm. It is expected that by adopting 5.4 nm abrasive grains and setting higher grinding speeds,the higher machined surface quality may be achieved within the simulation parameters range.
