Notes:
Strengthened coating on the surface of 35CrMo steel alloy was deposited byelectrospark process using NiCr electrode. The bond strength and microhardness of the coating waschecked and the microstructure of the strengthened coating was analyzed using the opticalmicro-scope, X-ray diffraction (XRD), scanning electron microscopy (SEM) and energy dispersionspectrum (EDS). The results show that the bond strength between the coating and the base metal is495.1MPa, and the hardness of the coating surface is about 2 times than that of the base metal, andthe property of the workpieces surface has become better. The coating is a metallurgical reactingbonding layer between the base metal and the NiCr electrode, and its main ingredients are FeNi andNiCrFe
