Dependence of the Nonuniformity of Thickness of the Vacuum-Arc Discharge Plasma Coating on the Geometric Parameters of the Inter-Blade Channel

When applying a vacuum-arc discharge plasma coating to profilecomposite items, such as twin turbine blades, unicycle blades, etc., a problem might occur with ensuring the tolerance on the coating thickness. This article presents the obtained dependence of the nonuniformity of the coating thickness on the geometric parameters of the inter-blade channel—its length and width. We develop a simulation model for calculating the distribution of the thickness of the vacuum-arc discharge plasma coating for the profilecomposite parts having shadow zones.
