Vacuum coating machine tool coating strengths and Development

2020-03-25 17:42  Times of view:

Rapidly vacuum coating machine coating technology, coated tools has been widely used. Guangdong Vacuum Coaters Baorui titanium company successfully developed a chemical vapor deposition (CVD) coating technology, and markets a product CVDTiC coated cemented carbide inserts. Baorui titanium have developed physical vapor deposition (PVD) process, the high-speed steel cutting tools PVDTiN products to market. CVD coating process temperature was about 1000 ℃, mainly used for the surface coating cemented carbide cutting tools (blades) of; the PVD coating process temperature is below 500 ℃ and 500 ℃, mainly used for the surface coating of high-speed steel cutting tools.

Later, CVD, and PVD coating technology has developed rapidly, vacuum coating, vacuum coating device in the coating material, coating apparatus and processes have made great progress, and the development of a multi-layer material coating techniques, so that coated tool (blade) of the performance has been greatly improved. Half position PVD coating technology is mainly used for high-speed steel cutting tools in the past, but in recent years with the rapid development of PVD coating technology, also used successfully for carbide cutting tools (inserts), occupied the carbide-coated tools (blades) of . Now, coated high speed steel and cemented carbide tool coated cutting tools (blades) are widely used, account for more than 50% of the total use of all tools.

Vacuum coating, vacuum coating equipment in good toughness on the tool (blade) surface coating the substrate, the coating having high wear resistance, high hardness, refractory sheet material (e.g. TiN, TiC, etc.), the tool (blade) has a comprehensive and good overall performance. Uncoated high speed steel hardness of only 62 ~ 68HRC (760 ~ 960HV), the hardness of cemented carbide is only 89 ~ 93.5HRA (1300 ~ 1850HV); and the surface hardness of the coating can reach 2000 ~ 3000HV or more.

① As the surface coating material having a high hardness and wear resistance, and high temperature. As compared with the cutter (blade) uncoated, the coating tool allows for a higher cutting speed, thereby improving the cutting efficiency; or can be at the same cutting speed, tool life.

② Since the small coefficient of friction between the coating material and the workpiece material so coated tool (blade) cutting force is less than the uncoated cutting tool (insert).

③ with a coating knife (blade) processing part is preferably machined surface quality.

④ Since good coating knife (blade) overall performance, it is coated cemented carbide inserts have good versatility, insert a coated carbide grade having a wide range of uses.

Vacuum coating machines, vacuum coating plant: HTCVD addition, there are a plasma chemical vapor deposition (a PCVD) process, which is another method for surface coating of carbide cutting tools (blades), because such a coating process lower temperature (700 ~ 800 ℃), so that the bending strength of the blade is reduced. Since the linear expansion coefficient TiC closest to the base material, usually first coated with a thin layer of TiC on the substrate surface, then cover the outer TiN, Al2O3, such as TiC / TiN, TiC / Al2O3, TiC / TiCN / TiN and the like.

Zunhua Baorui Titanium vacuum coating applications in a variety of equipment manufacturers, committed to the development and production of vacuum coating machines, vacuum coating equipment, has a huge technical team, and domestic vacuum industry veteran experts, professors and senior engineers, provide hundred of processes and vacuum coating equipment for you to choose!
