Ion-plasma coatings performance properties improvement obtained by arc deposition

Influence of micro-droplet phase content in erosion products of cathodes made of various materials on coating properties produced by vacuum ion-plasma electro-arc method has been revealed. Amount of micro-droplet phase and its fractional content in a plasma jet have been researched. Coefficient standard distribution of micro-droplet phase content depending on cathode material and production conditions, distance from the cathode to the deposition surface, arc current and the temperature of the cathode surface have been obtained. General manufacturing methods and design concepts to reduce micro-droplet phase have been formulated.
