METHOD OF DENSE COATING APPLICATION

摘要

application of coatings by spraying. SUBSTANCE: method includes spraying of coating material and treatment of coating by local heatings in places of maximum internal stresses of coating up to temperature of melting of metal components on metal-dense coating boundary. Local heating of sprayed dense coating may be carried out by resistance welding machine, laser plant, electron-beam plant, etc. EFFECT: higher adhesion and cohesion of sprayed dense coating without affecting of service properties of sprayed dense coating.
