sentinabay owns the technologies tisurf® and tribsurf. tisurf® gives titanium new features and with the new application areas. the tisurf® process deepens the titanium and gives a tisurf® surface that is 2-3 times harder than hard chrome, high abrasion resistance and low friction. tribsurf is a nano-level slip method that can be applied to hardsurfaces. tribsurf gives the surface of the material increased wear resistance and lower friction.
