Abstract (en)
[origin: EP0348608A1] A method is described of exposing silicon crystals on fine- machined, preferably honed surfaces of workpieces made from silicon alloys or from hypereutectic aluminium-silicon alloys such as Al Si 17 Cu 4 Mg, in which the silicon crystals (1) are embedded in a substantially softer matrix (2). To this end, the surface of the workpiece is treated with a brush (4 to 30) subsequently to the fine machining. <IMAGE>
