FIELD: coating metallic materials.
SUBSTANCE: method comprises setting the metallic article in the chamber filled with a gas aluminum composition mixed with argon or helium gas agent. The pressure of the gas agent is chosen so that the mean length free motion of its molecules is at least twice as much as that for the molecules of argon at the atmospheric pressure.
EFFECT: enhanced durability of articles.
