45 steel was grinded and hardened on a surface grinding machine to study the effect of three different cooling media, including emulsion, dry air and liquid nitrogen, on the microstructure and properties of the hardened layer.The results show that the microstructure of material surface hardened with emulsion is pearlite and no hardened layer.The surface roughness is small and the residual.
