Wear-Resistant Alloy for Protection of Contact Surfaces of Working Aircraft Engine Blades from Oxidation at High Temperatures

Section: Scientific and Technical Innovative Projects of National Academy of Sciences of Ukraine
Language: Ukrainian
Abstract: Wear-resistant and heat-resistant cast cobalt-based alloy for hardening of the contact surfaces of working blades of aircraft gas turbine engines instead of commercial alloys ХТН-61 and ВЖЛ-2 was developed. High levels of heat resistance were achieved by complex doping (modification) of the alloy. Based on studies of heat resistance, wear resistance, the structure and melting point of the alloys, the optimum chemical and phase composition of the developed alloy was defined.
Key words: cobalt alloys, niobium carbide, alloying, heat resistance, melting point, wear resistance.
