Changing the future with TiSurf Technology.

Titanium in new applications.

Tested and approved in extreme conditions

TiSurf® is a ceramic/metal hybrid material. A ceramic surface of titanium nitride 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.

New Solution Titanium - TiSurf®

TiSurf® components vs. steel components

TiSurf Shock absorber Piston rods

Shock absorber rods

  • 40% lower variable weight
  • No hard chrome
  • Surface evenness at nanoscale level
  • No corrosion
  • Better traction
  • Shorter braking distance
  • Lower fuel consumption

Finer surface provides less friction. Lower friction provides better handling. Better road handling provides shorter braking distances and lower fuel consumption, as well as greater comfort for passengers.

Engine Piston pins

Engine Piston wrist pins

  • 40% lower variable weight
  • Surface evenness at nanoscale level
  • Withstands higher temperatures*
  • Withstands higher loads
  • Lower emissions
  • Lower fuel consumption

Higher operating temperature of the engine produces less emissions and lower fuel consumption, but requires components that can withstand higher temperatures.

*Steel: 300-500o C, 800-1150 HV, hardness decreases with temperature.
TiSurf: 400-750 C, 2900-3100 HV, hardness highly temperature stable.

Storsatsning på världsunik titanteknik med säte i Mora och Sandviken

15 mars 2016

DalaDemoraten - Storsatsning på världsunik titanteknik med säte i Mora och Sandviken

– Framtidens konstruktioner måste vara lättare, hålla längre och ge längre friktion. Titan är 40 procent lättare än stål, säger Håkan Alfon, chef för Almi Invest som jobbar med riskkapitalinvesteringar.

10 mars 2016 - Almi Invest investerar i SentinaBays titanteknik

Globala krav på ekonomi och miljöprestanda ökar allt mer, vilket innebär att framtidens konstruktioner måste vara lättare, hålla längre och ge lägre friktion. Titan* är 40 procent lättare än stål och får med TiSurf® en härdning ner i metallen och en yta med låg friktion i keramik som är upp till 3 ggr hårdare än hårdkrom. TiSurf® bildar ett hybridmaterial (metall/keramik) med unik prestanda.

Sandbacka Park - SentinaBay utvecklar Tisurf

SentinaBay AB har sitt ursprung i Mora, men har nu sin bas på Sandbacka Park i Sandviken. Med ett nytillskott av 4,6 miljoner från Almi Invest och Sandvikeninvesterarna så ska det nya materialet ut på marknaden. Med det relativt höga priset på titan måste man hitta smarta och materialbesparande applikationer där materialet verkligen gör nytta.
