PEMSTM
technology
Our company uses PEMSTM (plasma enhanced magnetron sputtering) technology for vacuum deposition. Compared with the traditional vacuum deposition technology, not only can the coating with high density and high adhesion be obtained, but also it can be treated at low temperature without affecting the matrix properties of the parts.
This technology is especially suitable for establishing superhard cermet deposits with reduced friction coefficient and wear resistance.
Deposition of coating surface by cathodic arc method
Coating surface deposited by PEMSTM technology
The main advantages are:
A wide range of materials are processed (metal, ceramics, polymer, glass);
Uniform coating and accurate composition;
A machine has multiple functions and can run in multiple modes:
PVD
(physical vapor deposition)
form
-PECVD (plasma enhanced chemical vapor deposition) form
-Establish a composite deposition layer (e.g. TiN+DLC).
Simple operation, automatic computer control of deposition process and good stability;
The process is flexible, and the alignment procedure can be easily adjusted according to the specific requirements of customers, and the deposition quality can be optimized.
Before deposition, the parts and the target are automatically cleaned in the furnace at the same time to ensure that the deposited layer with high adhesion and accurate composition is obtained.
