PVD decorative coating and conventional chemical plating (water plating difference)

1. Similarities: both belong to the category of surface treatment, both through a certain way to make a material covered in another material surface.

2. Differences: (steel substrate comparison)

(1) PVD decorative coating is mainly applied on some high-grade hardware products, and the hardware products with lower price are usually only water electroplated.

(2) Some materials (e.g. copper, iron, alloy) can be water electroplated, not directly PVD coated.

(3) PVD film layer has greater bonding force with the surface of workpiece.

(4) PVD film layer is wear-resistant and has good corrosion resistance.

(5) PVD film layer is micron thickness, without affecting the original size of the workpiece to improve the surface of the workpiece various physical and chemical properties.

6) PVD layer is rich in color (by controlling the parameters) and easy to adjust.

7) Non-polluting and environmentally friendly coating, which does not produce toxic or polluting substances.

8) PVD coating technology can deposit high quality layer, but the cost is not high, it is a kind of cost-effective surface treatment.

(9) PVD coating is more extensive, can be plated with single gold color, two-element compounds, and even five-element compounds.

(10) PVD coating can realize true nanometer-sized layers or nanometer-sized multi-film layers.
