Characteristics of Coatings Sprayed by 3 cathodes Plasma Gun System

Abstract

The newly developed Three-cathode Plasma Spray Gun can produce plasma jet flame that has desired temperature and velocity distribution in a concentric circle, and it is expected to make homogeneous coatings with faster speed. We observed and tested the characteristics of the sprayed coating with this system such as structure, hardness, density, adhesion strength, thickness, etc to examine the applicability for industrial parts.
