Abstract

Wear- and heat-resistant casting cobalt-based alloy for hardening the contact surfaces of rotor blades of aircraft gas turbine engines has been developed to replace commercial alloys HТN-61 and VZhL-2. High heat resistance was achieved by combined doping (modification) of the alloy. The optimum chemical and phase composition of alloy has been found based on the study of alloy heat resistance, wear resistance, structure, and melting point.
