FIELD: applying of hardening coating. SUBSTANCE: eroded surface of details is affected by mechanical treatment followed by degreasing which is carried out with the help of benzine or acetone. Then shot-blasting treatment and detonation spraying take places. The latter process is carried out in series (each comprises 10-20 shots) at interval 0.5-3.0 min, uninterrupted blowing of sublayer with compressed air at pressure 2-4 atm takes place. EFFECT: higher efficiency of the method. 3 dwg, 1 tbl
