In dry environments, such as dry gas or vacuum, regular DLC coatings such as Tribobond™ 41/42/43 exhibit high friction and wear rates. Responding to the need to provide protection in such conditions, Ionbond developed the Tribobond™ 55 coating, specifically designed to overcome this limitation. This was achieved by modifying the structure and composition of the functional DLC layer. This customized layer maintains an extremely low coefficient of friction in most dry and vacuum environments, thus helping to reduce wear and energy losses related to friction. The Tribobond™ 55 coating is typically used on wear components of high-vacuum systems, as well as tribological applications running in dry gas environments.
