Gas-dynamic spraying, as a method of the component recovery in the power engineering industry

Abstract

The purpose of the study is to decide on the possible protective coating formation of “Ni-Al” system by applying the method of cold gas-dynamic powder spraying with “Dimet-403” unit. The phase composition, microstructure and mechanical characteristics of the coating after spraying and subsequent heat treatment have been investigated. The developed coating can be used for protection against high-temperature gas-phase corrosion of internal surfaces of working blades of gas turbine engines during their manufacture or repair.
