Diamolith (DLC)

A coating of extreme hardness and low friction produced by Plasma Enhanced Chemical Vapour Deposition (PECVD). The material contains carbon and hydrogen bonded in sp³ and sp² structures resulting in the excellent combination of mechanical properties.

The coating is a very dark grey to black colour and very smooth in texture. Desposition temperatures are low and the coating can be successfully applied to steel, aluminium and titanium alloy substrates.

Diamond-like Carbon Coatings (DLC) can be applied in a wide range of application where the exciting combination of hardness and lubricity can extend life and improve performance.

For tooling the high abrasion resistance and low sticking properties can improve life and decrease production costs.

Many mechanical wear parts can benefit especially in low and marginal lubrication conditions.

The coating has good bio-compatability with no inflammatory response and low platelet adherence, making the process attractive for the coating of many types of biomedical implant.
