FIELD: process engineering.
SUBSTANCE: invention relates to gas-thermal coating spraying, particularly, to detonation application of coating. Surface is subjected to abrasive particle flow produced with the help of detonation spraying unit. Powder is fed for cleaning at spraying mode from separate dispenser arranged at a distance from barrel exit. Note here that temperature and rate of cleaning particles at exit allow for maximum activation of sprayed surface. After surface preparation said dispenser is stopped while dispenser with powder for spraying of particles is activated without stoppage of detonation unit.
EFFECT: higher activation of sprayed surface and process efficiency.
