Technology for the Deposition of Wear-Resistant Coatings on the Airfoil Shroud Platforms of GTE Turbine Blades

Abstract

Experimental data are used to estimate the possibility of the deposition of a wear-resistant nickel-based VKNA-2M intermetallic alloy onto the contact surfaces of the airfoil shroud platforms of the gas turbine blades in a high-temperature gas turbine engine (GTE) by facing in an argon atmosphere. A technique is proposed to restore the geometric sizes of the wear-resistant coatings on the airfoil shroud platforms of gas turbine blades to increase the functional properties of the repaired coated parts.
