Direct coating method for the surface of the mirror surface
The invention relates to a method for direct coating on the surface of the mirror surface, which belongs to the technical field of aluminum and its alloy. The method includes water, dilute acid, alkali cleaning the surface of aluminum; aluminum after cleaning by ceramic materials for vacuum coating processing, forming a thin film on the surface of aluminum, the ceramic material Si3N4, Ti3N4? Which is made by the method of the invention of mirror aluminum, formed on the surface of the film layer is not only a variety of color, good appearance, corrosion resistance, wear resistance, anti defects; and the method has the advantages of simple technique, less environmental pollution, low production cost, is conducive to large-scale industrial production.
1. A mirror aluminum surface coating method. The method includes water, dilute acid, alkali cleaning the surface of aluminum; aluminum after cleaning by ceramic materials for vacuum coating processing, forming a thin film on the surface of aluminum.
2. According to the right request 1 the aluminum mirror surface coating method, its characteristics is that the dilute acid is the mass fraction of 1% 5% dilute hydrochloric acid, the mass fraction of 1% - 5% dilute nitric acid, the mass fraction of 1% - 5% dilute sulfuric acid A and the lye for inorganic alkali solution.
3 according to the right to require 1 or 2 of the mirror surface of the aluminum surface directly coated method, the characteristic is: the ceramic material is Si3N4, Ti3N4 in one or two.
4 according to the requirements of the 3 surface of the mirror surface direct coating method, which is characterized by vacuum coating on the aluminum sheet after the formation of film thickness of
5 Direct coating method for the surface of the mirror surface
