The Grindability and Surface Evaluation of Laser-dressed Metal Bonded Grinding Wheel

Abstract

Nd. YAG fundamental or second harmonic generation laser was applied onto an iron plate through 8-16μm diamond grains placed on the plate. Fundamental YAG laser could achieve more diamonds fixed on the plate with the irradiation than second harmonic. It was found that the number of diamonds fixed on a plate generally increased with laser flux density and irradiation period. AES analysis indicated the existence of carbides on the surface of a plate with laser treatment, which mentions that the diffusion of carbon causes upon the bonding of diamond and iron.
