Concept of film uniformity of vacuum electroplating machine

Vacuum electroplating mainly refers to a type of coating that needs to be carried out under high vacuum, including many types, including vacuum ion evaporation, magnetron sputtering, MBE molecular beam epitaxy, PLD laser sputtering deposition and many others. The main ideas are divided into two types: evaporation and sputtering. In the vacuum electroplating machine, what needs to be coated is called the substrate, the material to be plated is called the target, and the substrate and the target are in the same vacuum chamber. Evaporation coating generally refers to heating the target material so that the surface components are evaporated in the form of atomic groups or ions, and settle on the surface of the substrate to form a thin film through the film formation process. For sputtering coatings, we can simply understand that the target is bombarded with electrons or high-energy lasers, and the surface components are sputtered in the form of atomic groups or ions, and finally deposited on the surface of the substrate, going through the film formation process, and finally form a thin film.

Vacuum electroplating machine ion plating has fast deposition speed

Ion plating technology can be a very widely used coating technology. Because ion plating has the advantages of fast deposition rate, wide range of plated materials, good diffractivity, dense film layer, good adhesion, high fatigue life of the substrate, and alloying the surface of the substrate. Therefore, ion plating technology has a very wide range of applications in the fields of improving the corrosion resistance, wear resistance, heat resistance, lubrication and other characteristics of the surface of metal materials, and the scope is gradually expanding.

In recent years, due to the serious environmental pollution of wet electroplating, foreign developed countries attach great importance to ion plating technology and are gradually replacing wet electroplating. With the in-depth study of ion plating technology to alloy the surface of the substrate. It indicates that in the alloying of metal materials in the future, the common ion plating types and characteristics of ion coating machines will make ion plating technology an important means, and then it will be rejuvenated in the field of surface treatment technology.
