FIELD: technological processes.
SUBSTANCE: method includes layer-specific spraying of melted particles on part surface, at that heating of particles is carried out in plasma jet screened with supply of pyrophoric technological gas into spraying spot. Coating is sprayed from powder, initial mixture of which is taken with proportion of aluminium, copper and iron that corresponds to area of Al-Cu-Fe alloy quasi-crystalline phase existence, by heating it up to melt temperature in inertial atmosphere. At that part surface is cooled with coolant, and temperature in spot of spraying is maintanined in interval of 650-750°C.
EFFECT: preparation of coating from quasi-crystalline alloy of abovementioned system.
