PVD Ion Coating can be devided into two kinds: Decorative Coating & Tool Coating.
The thickness of decorative coating is thinner. Its main purpose is to improve the appearance effects of products, for example: the color, the brightness etc. Besides, the decorative coating also can reduce the surface abrasion, resist surface corrosion and prolong the lifetime of products.
The decorative coating is mainly applied on different kinds of hardware products, for example: watches and clocks, doors, windows and locks, door hinges and door handles, kitchen and shower equipment hardware, tablewares, scissors and knifes etc. The PVD coatings create an attractive, modern surface in a comprehensive range of colors, and can be color-matched to existing metallic surfaces.
The thickness of tool coating is thicker than that of decorative coating. Its main purpose is to prolong the lifetme of different kinds of hardware tools, cutting tools and moulds, for example: screwdriver, pliers, lathe tool, milling cutter, planer tool, drills etc.
The tool coatings can highly prolong the lifetime of products. For example, for the lathe tool, milling cutter, planer tool and drills, after they were PVD coated, the lifetime will be rising to 5~40 times. Meanwhile, because of the PVD coatings are very fine and have small friction coefficient, the cutting speed of machine tools and the cleanliness of product surface are all highly improved. These factors improve the productivity of the factories, and the machining accuracy and appearance of products are all be ameliorated. This will bring more benefits to the enterprises.
So far, the PVD coating technology has been widely applied in the building materials, lock hardwares, kitchen hardwares, watches and clocks, cutting tools etc. The PVD coating technology has bring abvious economic benefit to the enterpises and it also enhances the development potential of them. Today more and mroe engineers of manufactureing, building and designing industries have recognized the effects and special characters of the PVD ion coating.
| Sorts | Practical apply | Recommend coatings |
| Decorative coating | diffenent kinds of hardware products both in and out door | ZrN, TiN |
| kitchen hardwares, shower hardwares | ZrN, CrN, TiAlN | |
| Tool coating | cutting tools（lathe tool, milling cutter, planer tool, drills etc.） | TiN, TiAlN, TiCN, CrN |
| moulds | CrN | |
| mechanical parts（piston ring and others） | CrN |
.
The PVD coatings are not easy to flake off, or to be oxidised, or fade, or congregate dusts. The are easy to clean and have low coating cost. At the abundant technology base of our company, we can coat the following coatings onto the products of the material: stainless stee, iron, brass, titanium alloy, zinc aloy etc.
| Pure titanium (Ti) | Titanium nitride (TiN) | Titanium oxide (TiO) |
| Pure zirconium (Zr) | Zirconium nitride (ZrN) | Titanium carbide (TiC) |
| Pure chrome (Cr) | Chrome nitride (CrN) | Titanium carbonitride (TiCN) |
| Titanium aluminium nitride (TiAlN) |
The colors of PVD coating we often see are as following:
deep gold color, light gold color, brown, bronze-colored, grey, black, greyblack, iridescence etc.
There are six PVD coatings we often use. The links of them are at the right side of this page. Click on the relevant links can get the introduction of each coatings.
