aluminum material, the surface oxidation treatment and oxidation treatment of the mixture (a SURFACE NITRIDING METHOD of AN ALUMINUM MATERIAL, and AN AUXILIARY AGENT free on rail NITRIDING)

摘要

this invention is a silicon containing material on the surface of aluminum is relatively thick nitride layer formation of oxidation method and oxidation treatment of the group is to provide for the purpose.;lithium or other than oxygen and the theory of the strong force, and silicon and coexistence, in fact, in the side, do not form a metal containing aluminum as the theme of the oxidation treatment of the aluminum material or the magnetic uc298 - copper alloy or a magnetic air -. love theme - copper alloy is used for the oxidation treatment of the use of the material, oxidation treatment under the condition of nitrogen is in contact with the heat treatment. this is the silicon containing aluminum alloy material on the surface of a thick nitride layer also can be easy to form, and the casting of aluminum - silicon alloy, the surface oxidation of the best.
