Multi arc ion coating process how to apply? In some modern engineering applications, sometimes single coating technology has been unable to meet the special requirements, product performance improvement is also unable to reach a certain standard.
This is the compound technology of surface engineering technology development in one direction, and use the most is more arc ion plating and permeability composite coating process.
The process is: infiltration, composite plating process, it includes ion nitriding, ion plating, etc.; Composite plating process and composite process of arc ion plating and permeability, etc.
Workpiece prior to coating, ion nitriding layer can not only make the membrane resistance to deformation ability enhancement, and because the membrane layer under investigation more smooth transition region, can make the film to the substrate better stress distribution, so relative to the nitriding process, improve the mechanical strength of the coating.
By arc ion plating technology, can be in deposits a layer of metal or its alloy tool surface hard film, this is a common way to increase its life, but by raising the hardness increased life is limited, we should consider in the plated surface of molybdenum in situ synthesis of a layer of MoS2 solid lubrication film again in order to further improve the knives' service life.
What is the vacuum
Vacuum means that a given gas pressure within the space of less than the area of a standard atmospheric pressure gas state.
Vacuum is rarefied gas environment. Compared with the atmosphere it has a number of advantages, such as gas thin, less oxygen, clean environment...
