PONCE, Ernesto; MARTINEZ, Luis  y  VARGAS, José. BORONIZADO DE ALEACIONES DE BASE COBRE. Rev. Fac. Ing. - Univ. Tarapacá [online]. 2004, vol.12, n.2, pp. 57-62. ISSN 0718-1337.  doi: 10.4067/S0718-13372004000200008.

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 Steel-Bronze 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 high melting point and low friction coefficient, thus reducing wear and exhibiting a better tribological performance
