Abstract
Sliding layers overlays produced by cathode sputtering comprise a matrix-forming metallic material and at least one other material which is substantially insoluble in the matrix have greatly improved mechanical and corrosion resistance properties, if the insoluble material has a lower melting point than the matrix material, and if the diameters of the particles of the insoluble material are statistically normally distributed with mean x<0.8 .mu.m. Such overlays are produced with the temperature of the substrate maintained below 150.degree. C. during the sputtering process. Coating rates of >0.2 .mu.m [of layer thickness] per minute may be used informing such overlays.
