PVD vacuum coating technology is what mean?

According to the relevant provisions of the export since June 1, the coating (coating) products, must accord with standard of Europe and the United States environmental protection, the domestic electroplating (water) plating industry undoubtedly is a huge shock. Export products will be replaced by vacuum ion deposition (PVD) technology. In order to promote the replacement of the pearl river delta region of the promotion and application of surplus and the company has set up a service center in shenzhen. Set 'vacuum coating machine/power supply/technical guidance to maintain/process development/production and processing as one, to the pearl river delta market provides the omni-directional service.
Electroplating in industrial applications already a long time, but it membrane was not enough density, porosity, light coating machine is easy to hydrogen embrittlement, more serious pollution to the environment is bad, "three wastes" treatment is costly and cannot be eradicated. Especially hexavalent chromium, nickel, cadmium is harmful to human body, is a carcinogen. So the plating is replaced industrial development inevitable. Dalian university of technology from 1980 project is engaged in steel, brass parts, vacuum ion plating of aluminum base alloy replace electroplating research has been more than 20 years, has now successfully in steel, brass, aluminum alloy, zinc base alloy base material surface of ion plating chromium, titanium, zirconium, aluminum, nitride, etc. Alternative electricity galvanized, electroplating, plating nickel cadmium, chromium plating. Multi arc ion coating machine has applied for Chinese patent for invention has: the middle tier of the ion plating chromium alloy + ion plating (dark silver) + ion plating, ion plating layer alloy titanium or zirconium + ion plating transparent ceramic coating (golden brown), completely solve plating defects.
