Problems solved by technology
[0003] As we all know, most of the components of electronic products must be anti-EMI (Electromagnetic Interference translated as electromagnetic interference) treatment. The existing technology uses water electroplating to pollute the environment.
Obviously, the use of water electroplating for EMI treatment pollutes the environment, violates the consumption concept of consumers, and reduces the market competitiveness of products. Living in a cleaner and more beautiful environment, the market demand for antibacterial products will become more and more strong

Abstract
The invention provides a process with micro arc oxidized work piece EMI resistant and antibacterial effect, which comprises the following procedures: base material selection->base material surface pre-treatment -> micro arc oxidization -> micro arc oxidized work piece surface treatment -> EMI sputtering -> electrophoretic coating; first, a selected base material receives surface pre-treatment and micro arc oxidization, to obtain a micro arc oxidized work piece; the micro arc oxidized work piece is washed and a metal layer is coated on the surface of the micro arc oxidized work piece through EMI sputtering, so that the surface of the micro arc oxidized work piece is EMI resistant and conductive; the conductive micro arc oxidized work piece receives electrophoretic coating treatment, and the electrophoretic coating used is antibacterial; the work piece treated by the process has the ceramic, EMI resistant and antibacterial effect, very good application prospect, and improves the market competitiveness of the product.
Description
【Technical field】 [0001] The invention relates to a surface processing technology of a micro-arc oxidation workpiece, and in particular to a processing technology for making the micro-arc oxidation workpiece have anti-EMI and antibacterial effects. 【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 ceramicization technology, a high-tech that has developed rapidly at home and abroad in recent years. MAO is a high-quality reinforced ceramic film formed in situ on the surface of workpieces made of Mg, Al, Ti, Zr, Ta, Nb and other metals or their alloys (called Valve Metal). This technology is a surface modification technology of metal materials with broad application prospects. [0003] As we all know, most of the components of electronic products must be treated with anti-EMI (Electrom...
