The application of PVD coating technology is mainly divided into two categories: decorative plating and tool plating. The purpose of decorative plating is to improve the appearance of the workpiece and its color and to make the workpiece more wear-resistant and corrosion-resistant to extend its service life. This aspect mainly applies hardware industry, be like door window hardware, lock, hardware and so on industry. VD Coating Systems Manufacturers The purpose of tool plating is to improve... read more
1. High hardness – hardness is an important performance index to measure the degree of compressive deformation of product materials. Let's look at a set of data: HV - Vickers Hardness Evaporation Vacuum Coating Machine ManufacturersA nickel layer thickness 0.005 hardness - about 180HVB hardness of electroless nickel plating containing phosphorus - about 300HVC Hardness of aluminum substrate -- about 100HVHardness of anodized film - about 300HVHardness of hard anodized film - about 500HVD Hardnes... read more
At the present stage, PVD coating cannot replace chemical electroplating, PVD coating can be done directly on the surface of stainless steel materials, but many other materials (such as zinc alloy, copper, iron, etc.) should be electroplated by Cr(chromium) before PVD coating.VD Coating Systems Manufacturers PVD coating is mainly used for some high-grade hardware products. For those hardware products with low price, it is usually only used for electroplating instead of PVD coating. read more
PVD is the abbreviation of Physical Vapor Deposition (Physical Vapor Deposition). It refers to the practice of using low-voltage and high-current arc discharge technology to vaporize the target material and ionize both the evaporated material and gas under vacuum conditions. By using the acceleration of electric field, the evaporated material and its reaction products are deposited on the workpiece.China PVD Coating Systems Manufacturers PVD (physical vapor deposition) technology is mainly ... read more
Several common vacuum pumps in vacuum coating technology Diffusion pump Diffusion pump is one of the most widely used and main tools to obtain high vacuum, usually referred to as oil diffusion pump. Diffusion pump is a kind of secondary pump, it needs mechanical pump as the front pump.Plasma Coating Machine Manufacturers Danko Vacuum Technology Company Ltd is committed to expand our market boundaries by providing high-quality, high-performance vacuum coating equipment.
