Abstract

The effect of repeated use of the chrome-calorizing powder mixture on the thickness and structure of the diffusion coating in the repair of gas turbine engine blades was investigated. The experimental study showed that reuse of the powder mixture results in a change in the mechanism of formation of the diffusion coating. The mechanism of sticking of the powder mixture during deposition of the protective coating on the turbine blades was determined.
