  • Process for tempering the surface of a body
    Patent number: 5318799
    Abstract: For tempering the surface of a body, the body is covered with a sheath of at least one meltable active substance and binder material and heated under vacuum or in an inert atmosphere first to a temperature whereby the sheath is transformed into a porous cover layer with outer crust. Then the temperature is raised until the meltable active substance contained in the cover layer is evaporated. On the one hand, the meltable active substance seals the outer side of the cover layer, and on the other hand, the meltable active substance produces the tempered surface of the body. After the body has cooled, the residues of the cover layer are removed. The body is provided with a pore-free resistant surface.
