FIELD: metallurgy.
SUBSTANCE: proposed method comprises application of wear-proof powder by detonation deposition on inner cylindrical surface of the hub of diametre D and length L with the help of detonation barrel of diametre d equal to (0.7-0.8)D. Detonation unit barrel is set at (2-3)D from inner cylindrical surface and directed at inclination thereto of arctg(D/L)±5°. Barrel is aimed at the center of deposited collar, that is, at the point located at inner cylindrical surface at spacing of L/2±1 mm.
EFFECT: higher quality of applied wear-proof coat.
