Abstract

A method for coating a sealing surface that rotates with respect to a countersurface, e.g. sealing surfaces of pumps in petro-chemical and wood-processing industries comprises the combination of use of high energy plasmaspraying, the spraying mixture comprising 80-94 weight-% tungsten carbide and 6-20 weight-% cobalt nickel or iron and the grain size of the spraying mixture being 5-60 mu m, and allowing the coating to cool after plasmaspraying without sintering it afterwards so that a certain porosity remains on the coating. <IMAGE>
