Abstract

The invention provides a process for processing a micro arc oxidized work piece through a technology of vacuum sputtering and electrophoretic coating, which comprises the following procedures: base plate selection -> base plate surface pre-treatment -> micro arc oxidation -> vacuum sputtering -> electrophoretic coating; first, a selected base material receives surface pre-treatment and surface micro arc oxidation, so that the selected base material becomes a micro arc oxidized work piece; and then a metal layer is coated on the surface of the micro arc oxidized work piece through vacuum sputtering, so that the surface of the micro arc oxidized work piece is conductive; the conductive micro arc oxidized work piece receives electrophoretic coating treatment, and the electrophoresis coating in corresponding color is selected according to the required color of the work piece; the work piece treated by the process can have appearance with required colors by adopting electrophoresis coating in different colors, has the effect of ceramics of color transparency, quite strong metal texture, and very good application prospect.

Description

【Technical Field】 [0001] The invention relates to a processing technique of a micro-arc oxidation workpiece, and particularly relates to a technique of processing a micro-arc oxidation workpiece by using vacuum sputtering combined with electrophoretic coating technology. 【Background technique】 [0002] Micro-arc oxidation technology has developed rapidly due to its simple process, high efficiency, no pollution, and strong processing capacity. Microarc oxidation (MAO) is the abbreviation of micro-plasma surface ceramization technology, a high-tech that has developed rapidly at home and abroad in recent years. MAO is an in-situ production of high-quality reinforced ceramic film on the surface of a workpiece made of metals such as Mg, Al, Ti, Zr, Ta, Nb or their alloys (called Valve Metal). This technology is a metal material surface modification technology with wide application prospects, especially suitable for high-speed rotation and surface treatment of metal parts that are easy...
