Since entering the 21st century, along with the development of modern industrial technology, more and more refined parts have higher requirements on most parts, whether it is appearance or performance. Faced with these strict requirements, traditional parts processing methods and surface treatment techniques have not reached the standard. After a long period of research and development, titanium plating has solved such problems. Titanium plating can not only meet people's requirements for wear resistance, corrosion resistance, less wear and other performance of parts, but also solve the problem that parts materials cannot withstand high temperature environments, and successfully keep parts from deformation. A state in which hardness does not decrease.
Vacuum multi-arc ion coating machine technology Titanium plating is a process for surface treatment of metal materials. It has been widely used in the industrial field and has the intention to gradually promote its use.
At the end of the 1970s, humans have already started physical vapor deposition technology, that is, PVD technology. Physical vapor deposition technology can be applied to the manufacture of hard films, which can improve the mechanochemical properties of products, make the manufactured products have high wear resistance, high hardness and other properties, and can also reduce friction. When this technology was first used, it aroused great repercussions in tool manufacturing industries all over the world and was highly valued. At the same time, this technical process meets the requirements of modern people for environmental pollution-free processing technology, and is a green and environmentally friendly technology.
The titanium plating process of the multi-arc ion coating machine is a coating technology that uses a variety of materials, and its processing temperature must be kept above 150 degrees Celsius, but not more than 500 degrees Celsius. Titanium plating can not only make the tools rich and colorful, but also the effect of the tools reaching a certain hardness. The use of PVD technology makes the tools have excellent performance.
If the pressure is not low enough (or the vacuum degree is not high enough), good results cannot be obtained. For example, if aluminum is deposited on the order of 10 2 Torr, the obtained film is not only not bright, but even gray and black. And the mechanical strength is extremely poor.
Thin film deposition technology is mainly divided into three major processes: physical, chemical, and epitaxy. Physical vapor deposition is referred to as PVD vacuum coating machine. Chemical vapor deposition is referred to as CVD coating machine for short.
In the vacuum chamber, when the particle concentration in the gas phase and the pressure of the residual gas are low enough, these particles can keep flying in a straight line from the evaporation source to the substrate, otherwise, they will collide and change the direction of motion.
Vacuum coating equipment uses two common coating processes, evaporation and sputtering. These two processes are currently the most popular and widely used, and their attention is naturally much higher than other processes.
