Diamolith DLC

Pure hard Diamond-like-Carbon Engineering Coatings

Diamolith™ is a pure diamond-like carbon coating deposited by Plasma enhanced Chemical Vapour Deposition (PECVD). Diamolith™ is deposited by vacuum based process where precursor gases are introduced into the process chamber and are broken down within the ionized plasma into various species of carbon, hydrogen and other dopants which are subsequently condensed as a solid entity onto the substrate surface.

The resultant coating has a number of unique properties that can be imparted on to the substrate to improve performance of the DLC coatings are a family of coatings made up primarily of carbon chains in an amorphous structure with sp2 (triagonal graphite form) and sp3 tetrahedral (diamond form) bondings.

Tribology Enhancement

• Diamolith™ DLC coatings are used to prevent wear due to its excellent tribological properties. It is very resistant to abrasion and adhesive wear making it suitable for the use in applications that experience extreme pressure both in rolling and sliding contact such as a hip prosthesis system.
• Diamolith™ is also suitable for the enhancement and preservation of cutting edges on medical instruments. The coating is also used in highly loaded automotive applications such as cam followers. piston pins and machine wear components across a wide cross section of industry
• Diamolith™ will reduce wear during the component break in period and will provide outstanding lubricity to minimize potential wear systems developing which, when coupled with pre-coat polishing, can result in the virtual elimination of the wear mechanism

General Overview of Diamolith Coating Properties

Diamolith™ is a hard, wear resistant, carbon based Coating. Diamolith™ provides excellent surface finish and smooth surface replication. Also provides very low coefficient of friction, which improves with use and lubrication. Diamolith™ has a dense and amorphous structure providing excellent corrosion resistance. The PECVD process allows three dimensional parts to be coated with thickness conformity around the geometry.
