Coating

DLC

DLC+ thin-film is produced in a high-vacuum chamber by a physical vapor deposition process.
During the PVD process, benzene is disassociated and ionized by a DC arc discharge (plasma). The resulting ions migrate towards the substrate to be coated which is negatively biased relative to the plasma. Collisions between ions in the gas phase result in the formation of both SP2 and SP3 bonded carbon structures which are then deposited on the substrate surface.

Developed to resolve Mechanical, Optical and Electronics problems, DLC+ coating is the answer to your needs as its tribological properties are exceptional. It brings wear resistance, chemical inertness, build-up resistance and low friction coefficient.
