PVD vacuum coating on the metal for cosmetic display

For the high-end cosmetic display , normally they are with metal decorative with PVD vacuum coating . what is PVD ??

PVD is Physical Vapor Deposition.. It refers to the film preparation technology that physically deposits materials on the workpiece to be plated under vacuum conditions.

the specific principle is to use low-voltage, high-current arc discharge technology under vacuum conditions, using gas discharge to vaporize the target and make the vaporized material not gas Ionization occurs, and the accelerated matter of the electric field is used to deposit the evaporated substance and its reaction product on the workpiece.

 PVD coating technology has high hardness, high wear resistance (low friction coefficient), good corrosion resistance and chemical stability, and the life of the film layer. Longer; at the same time, the film layer can greatly improve the appearance of the workpiece.

Thickness of PVD coating layer—The thickness of PVD coating layer is micron-scale and thinner, generally 0.3μm to 5μm. The thickness of decorative coating layer is generally 0.3μm ~ 1μm, so it can be affected by almost The physical properties and chemical properties of the surface of the workpiece are improved with the original dimensions of the workpiece, no further processing is required after plating.

Similarities and differences between PVD coating and traditional electroless plating (water plating) - PVD coating is not the same as traditional electroless plating. Both are in the scope of surface treatment, which are to cover one material in another through certain means. The surface of the material. The similarity between the two is that the PVD coating layer does not have a stronger bonding force on the surface of the workpiece, the hardness of the film layer is higher, the wear resistance and corrosion resistance are better, and the performance of the film layer is more stable; there isn’t any Toxic or contaminated substances when the process of PVD coating film
