This paper shows the heat treatment of some copper alloys employing Boron salts. The main objective is to produce a stronger metal layer and smaller friction coeficient than the original alloy, for application on SteelBronze moving parts such as bearings, gears, cams, worm gears and slide mechanisms. The advantage of the method is based on the atom of Boron, smaller than the others, who easily diffusses in the surface of the base metal. Very well defined layers of mono or poly phases Boron compounds may result, having h igh melting point and low friction coefficient, thus reducing wear and exhibiting a better tribological performance.
