Cathodic arc deposition of coatings onto the surface of products with a complex geometry (coupled turbine blades, integrally bladed disks) can be complicated by the problem of the coating thickness tolerance. This paper suggests experimental dependences between nonuniformity of the coating thickness synthesized by cathodic arc deposition and geometrical parameters of the blade channel, namely its length, width, and curvature radius.
