Article Preview

The grind-hardening of steel 65Mn had been carried out on a conventional surface grinder with alumina grinding wheel, the influence of depth of cut on the microstructure and the microhardness of workpiece, the depth and its uniformity of grind-hardened layer were studied. The results show that the completely hardened zone of grind-hardened layer is composed of fine acicular martensites, residual austenites and a little carbide. The variety of depth of cut has no obvious influence on the microstructure and the microhardness of completely hardened zone of grind-hardened layer. The maximum depth of grind-hardened layer and the depth uniformity of grind-hardened layer of workpiece increases with the increase of depth of cut ap.
