We all know that there are many types of Vacuum coater, applied to different industries, its production capacity and process are different, the properties and performance of the coating film are also very different, general customers purchase Vacuum coater is to first understand the process, to see whether our coating process can be done, whether they can meet the standards they want, will be further detailed understanding, The advantages of vacuum coating machine, as well as the strength of the company scale. The following Huicheng vacuum Xiaobian will introduce the classification of the film properties and uses of the vacuum coating machine, hoping to help you:

The PVD coating is an anodic coating on steel parts under atmospheric conditions. After color passivation, the PVD coating obviously improves the protection performance and appearance of the coating. PVD coating is mainly used to prevent corrosion of steel parts, PVD coating has low price, excellent corrosion resistance and wide application.
Cadmium coating in the ocean and high temperature atmosphere environment, PVD coating for steel parts as anodic coating, PVD coating is relatively stable, strong corrosion resistance, good lubrication performance, PVD coating in the aviation and electronics industry more applications. PVD coated tin coating is negative polarity coating on steel parts. The PVD coating has no pores in order to mechanically protect the steel parts from corrosion. PVD coating has high chemical stability, PVD coating and sulfur and sulfide almost have no effect, good welding performance, shielding effect on nitriding.
PVD coating copper coating on zinc, iron and other metals for negative polarity coating, PVD coating is often used on steel or some plastics as copper/nickel plating protective decorative coating bottom or middle layer, PVD coating can also be used in printed circuits, electric casting mold and other aspects. Nickel coating Nickel coating for steel parts is negative polarity coating, PVD coating has higher hardness, higher corrosion resistance than copper, alkali resistance, but also more acid resistance. PVD coating is often used for copper/nickel/chromium protection of steel parts - intermediate layer of decorative coating and pre-plating before acid copper plating.
