The removal mechanism of nano-zirconia materials includes brittle fracture and plastic removal. Brittle fracture involves crack formation, extension, peeling, and chipping to completely remove debris. Plastic removal is similar to chip formation in metal grinding, including rubbing, ploughing, and the formation of grinding debris.
micro while the grinding in nano scale, the cutoff distance in measuring surface roughness may be the reasons of this result because in nano scale the cutoff distance is very small i.e.about 2-4 nm while in micro it is about 0.8-1 mm. 2.0 CONCLUSION: The surface roughness in each case will indicate only qualitative value.
