Creation of a fundamentally new technology for the production of complex alloyed powders of CoCrAlYSi alloys with increased to 13% of the mass. Al for the application of thermal barrier coatings on the turbine blades of gas turbines
popup.description2
The object of the study is the physicochemical phenomena accompanying the processes of obtaining materials containing refractory, low-melting and rare-earth elements in their composition, by electron beam melting methods and powder technologies.
The purpose of the work is to develop methods that include electron beam and powder technologies for obtaining complex alloyed heat-resistant alloys based on NiCoCrAlY alloys for the deposition of protective coatings of increased resistance.
Research methods - optical and electronic scanning microscopy, methods of X-ray structural, chemical analytical, mass spectroscopic and other types of analysis.
The scientific basis of the technology has been developed, which includes a technological scheme for refining heat-resistant alloys NiCrAlSi and CoCrAlSi by electron beam remelting and obtaining powder with minimal oxidation of chromium, aluminum and yttrium, which, unlike traditional production schemes, allows solving the problem of effective processing of waste heat-resistant alloys CoCrAlY at Ukrainian enterprises producing gas turbine engines and gas turbine plants, and obtaining coatings with increased heat-resistant properties.
