Plasma coated or SUMEbore® cylinder bores use a plasma process to spray one of many different coatings on the surface. This coated surface is typically somewhat porous and must be finish-honed to achieve the final surface. The finish-honing process for plasma cylinder bores typically involves very fine abrasives, and the resulting surface is made up of a very fine peak surface with exposed porosity.
Much like plateau honing, the plasma surface provides a “broken in” texture with a smooth upper surface and porosity for lubrication retention and debris collection.
