Description

technical field [0001] The invention relates to a device for preparing a superhard abrasive grain layer by using an electric spark deposition method. The superhard abrasive grain layer can be prepared on the circumferential working surface of an old metal matrix grinding wheel by using the device. Background technique [0002] EDM is a technology that melts the conductive material in the electrode into the surface layer of the metal substrate through spark discharge, forms a metallurgical bond with the base material, and improves the physical, chemical and mechanical properties of the substrate surface. EDM deposition technology not only improves the mechanical, metallurgical, physical and other properties of the material surface, improves the wear resistance, corrosion resistance, fatigue resistance and other properties of the material, but also meets the requirements for the working surface of the material in the production field, and reduces the overall uniformity of the m...
