Abstract (en)
The process of producing a stainless steel coating on a part of a copper surface, comprises projecting non-molten or partially molten stainless steel particles on a copper matrix using a hot gas vector (2) at 70[deg] C, and heating the gas using a spray gun (1) comprising a heating unit (4). The hot gas vector is heated at a temperature of more than 700[deg] C. The stainless steel particles have an average size of 5-50 mu m. The coating has a thickness of 10-500 mu m. The copper matrix is a tubular piece or a plate. The gas is distributed at a speed of 400 m/s.
