Oerlikon Balzers launches new coating
Oerlikon Balzers has developed a process which allows a diamond-like coating (DLC) to be applied to high-friction components using Scalable Pulsed Power Plasma (S3p); a technique which combines the advantages of the arc evaporation and spluttering methods. This means that treated surfaces can now offer high hardness, low friction and a smooth surface.
This S3p technology generates a high level of tetrahedral bonds, with hardness up to 40 GPa, far higher than the 20-30 GPa offered by a typical DLC coating.
As such, the new BALIQ CARBOS coating exhibits three times lower wear in a calo test than a 20 GPa hard DLC coating.
In addition, Oerlikon Balzers’ new coating delivers both the low friction of carbon coatings, with the smoothness usually associated with the splutter process, giving a roughness of Ra= 0.03 μm. Moreover, this smoothness is achieved without the requirement for any additional polishing treatments.
