ABSTRACT:
A method of providing an improved friction surface and a friction element having such an improved friction surface are disclosed. A surface of a metallic friction element, e.g. a brake pad or a brake disc or drum, is metal-sprayed with a metallic substance which defines asperities the average roughness Ra of which ranges between 3 and 60 microns. Preferably, at least some of the asperities have heights ranging between 20 and 40 microns for a base width between 0.5 and 1 mm.
