Coating target is a kind of sputtering source to form various functional films on the substrate by magnetron sputtering, multi arc ion plating or other types of coating system under appropriate process conditions. In short, the target material is the target material bombarded by high-speed charged particles. When it is used in high-energy laser weapons, different power densities, different output waveforms and different wavelengths of laser interact with different targets, different damage effects will be produced. For example: evaporation magnetron sputtering coating is heating evaporation coating, aluminum film, etc. By replacing different targets (such as aluminum, copper, stainless steel, titanium, nickel targets, etc.), different film systems (such as super hard, wear-resistant, anti-corrosion alloy films, etc.) can be obtained.

Nickel is mainly used in electroplating industry. Nickel plated articles are beautiful, clean and not easy to rust. Very fine nickel powder, commonly used as catalyst in chemical industry. Nickel is magnetic and can be attracted by magnets. Alloys made of aluminum, cobalt and nickel are more magnetic. Application: coating industry, electron tube grid, high temperature components of vacuum furnace, X-ray target, etc.
