The uncovering compound and uncovering apparatus according to the uncovering process according to

摘要

The present invention relates to an uncovering compound to the exposure of the surface of materials with pronounced si - crystals, in particular cylinder bearing surfaces made from aluminum - materials with pronounced si primary crystals -. The uncovering compound according to the invention preferably has a very fine uncovering material, particularly preferably made of silicon carbide grains with a grain size in the range from 4 μm to 0,1 μm and / or ceramic fibers made of al₂O₃, , which is inserted into a tough - elastic plastic carrier composition is embedded. Furthermore, a method according to the invention, and a corresponding apparatus is described, the uncovering compound according to the invention is used.
