FIELD: machine building.
SUBSTANCE: spattering is performed by high-speed gas-flame method with the torch movement speed relatively to the treated surface 0.5÷1.0 m/s. Applied powder contains amorphous phase. Spattering is performed with surface temperature keeping at level 90±10°C by creation of the additional shielding gas flow in the spattering zone. In each layer the torch is moved with step h. In each next layer the torch is shifted by distance s relatively to the previous layer such that h=1.8s÷2.2s.
EFFECT: increased service life of the protecting coating due to its increased corrosion resistance.
