Tribobond™ 55
Special coating for vacuum and dry environments
Tribobond™ 55 is a specialty coating, which was developed to address tribological applications in dry environments, such as dry gas or vacuum. Regular Diamond-Like-Carbon (DLC) coatings, like Tribobond™ 41/42/43 do not perform well in such conditions, since they need humidity to form a lubricating layer and reduce friction.
Tribobond™ 55 is specifically designed to overcome such limitation, which is achieved by modifying structure/composition of the functional DLC layer. This customized layer allows to maintain an extremely low coefficient of friction in most dry environments, thus helping to reduce wear.
