Electrospark coating


It is based on the use of plasma pulsed spark discharges in the air and deposition of consumable electrode material on the product surface.


Application of coatings, mainly, 30-100 microns thick with the use of electrode materials from hard alloys, steels and cast irons, based on carbides, borides, copper alloys, nickel, tin, silver, graphite, etc.


The optimum mode of coating application is based, for example, on reached the specified coefficient of microhardness increase, required roughness parameters when the specific energy of a single pulse is used and its duration. The electrode material is selected in accordance with the desired application of the applied coating.
