Changing the future with TiSurf® Technology.

Tested and approved in extreme conditions

TiSurf® is a ceramic/metal hybrid material. A ceramic surface of titanium nitride (TiN) makes titanium parts 10 times harder and more wear resistant, with the added qualities of extremely low friction and exceptional corrosion resistance. TiSurf® has been successfully applied in several prestigious and demanding applications in the aerospace, offshore and racing industries. To date, TiSurf® has been involved in seven different NASA/ESA missions including Rosetta and Cassini, piston rods for Statoil’s oil platforms in the North Sea, racing projects in F1, LeMans and MX, and medical applications such as heart valves and catheters for hemodialysis.

TiSurf® is a hardening of the surface, not a coating. The titanium nitride that is formed through the diffusion of nitrogen into the titanium substrate becomes fully integrated into the original material, creating a ceramic-metal hybrid, where neither material can be separated from the other; they become “one”.

Cassini – The beginning of the end

On the 26th of April, 2017, Cassini will make its first daring dive between Saturn and its innermost rings. After completing the 22 orbits of “The Grand Finale”, it will ultimately plunge down into Saturn’s atmosphere, where it will be vaporized within minutes and forever become a part of Saturn.
