PVD coating machine coating theory
Release time:
2022-04-30
PVD coating machines are standard terminology in surface treatment. They transfer molecules or atoms of material to a substrate through a physical process, giving the substrate special properties such as high strength, wear resistance, and heat dissipation. PVD coating machines are one of the active factors in coating and processing systems.
PVD Coating Machine One of the active factors in coating and processing systems. With the development of technology, the feed rate and cutting speed of coating tools have been improved, and the service life has been extended. Therefore, with the rapid development of today's processing technology, the performance of tools has always been valued, and coating technology is a key technology in tool manufacturing. The PVD coating machine is a standard term for surface treatment, which transfers material molecules or atoms to the substrate table through a physical process, giving the substrate special properties such as high strength, wear resistance, and heat dissipation.
1. Main Characteristics of Coated Tools
Coated tools have the following characteristics:
(1) The surface coating material has the characteristics of high wear resistance, high hardness, and high temperature resistance.
(2) Coated tools have good comprehensive performance, further improving the versatility of coated tools and giving them a wider range of applications.
(3) With the rapid economic development of China's science and technology, coating technology has also been socially developed, and the oxidation resistance and high-temperature resistance of coated tools will become more prominent, completing high-speed cutting processing and improving cutting work efficiency.
2. Development of PVD Coating Machine Coating Technology
The deposition temperature of the PVD coating machine is usually maintained at 500 °C, and the coating thickness should be maintained between 2-5 μm; the deposition temperature of this method does not exceed the tempering temperature of the steel itself, so the PVD method is often used in the tool coating process. PVD coating machine coatings are mainly divided into three categories:
(1) Vacuum evaporation coating.
This technology has a short development time, the equipment used in the coating process is relatively simple, and the coating is very fine. Target materials need to be used in the deposition process, and the diffraction is relatively poor, which cannot meet the needs of superhard materials in the deposition process, which limits the application of this method, and its application range has gradually shrunk in recent years.
Modern design tools are often used in high-speed economic cutting. In order to meet this development need, coating cutting tools produced using the PVD method have been widely researched and applied, and have been rapidly promoted by society.
3. Performance of PVD Coating Machine Coating
If the performance of the PVD coating machine coating is to be fully realized, it is necessary to optimize the production conditions involved in the specific production process.
Clean the substrate surface, which is the same for all surface equipment, and the adhesion of the coating is affected by the surface state of the substrate. Therefore, in the specific coating process, oxides and other materials on the surface of the substrate must be removed. Generally speaking, for the surface and oil layer of the substrate, rust can be removed by sandblasting or cleaning methods. If sandblasting is used in the surface treatment process, it should always be noted whether there is oil stain on the surface of the substrate.
