Abstract
Technology envisages preliminary deposition by microplasma process of a protective coating on high-nickel alloy blade with its subsequent remelting by the electron beam. Programmed heat input provides partial melting of the matrix to not less than 30...50 mkm depth
Keywords: microplasma deposition of coatings, electron beam processing, gas turbine blades, high-temperature high- nickel alloys, defects
