Changing the future with TiSurf Titanium Technology.

TiSurf® - New Solution Titanium

TiSurf® is a process that converts the surface of the metallic titanium into a ceramic titanium nitride.

The TiSurf® diffusion method transforms the titanium from the surface down through the metal, providing a hardness gradient that increases from the interior of the metal (115 ‐ 460 HV) through to the surface (up to 3 100 HV). The thickness of the titanium nitride layer can also be controlled in the conversion process.

TiSurf® provides real hybrid material possibilities!

TiSurf® is approved for titanium (grades 1, 2, 3, 4, 5, 7, 9 and 23) and zirconium.
