METHOD FOR ALUMINISING FROM VAPOUR PHASE OF HOLLOW METAL PARTS OF GAS-TURBINE ENGINE Russian patent published in 2013 - IPC C23C10/48 B22F3/12 

FIELD: metallurgy.

SUBSTANCE: halogenide is obtained by means of a reaction between halogenide and metal donor containing aluminium; then, halogenide is carried with carrier gas to come into contact with inner wall of the blade of the above nozzle guide vanes. The above metal donor is arranged at least partially in the above cavity. The above blade includes a cavity with a hole for supply of cooling fluid medium. The above metal donor is used as a bar that is introduced through the hole for supply of cooling fluid medium and that is obtained by high-temperature sintering under pressure of metal powder containing aluminium in the quantity of 30 to 80 atm %.

EFFECT: obtaining coating of walls of inner cavities of metal parts throughout the surface and of required thickness.
