Abstract : This invention relates to a method of making titanium alloy more resistant to sliding wear and fretting fatigue comprising the steps of: implanting carbon ions with at least one energy onto titantium alloy until at least 1 x 10 to the 17th power carbon ions/ sq. cm have fallen onto the titanium alloy, said energy level of carbon ions being implanted being greater than 10 KeV. A second method comprises an additional step of heating the implanted titanium alloy to between 300 C. and 500 c. for 0.5 hours to 2 hours. The second method has a lower number of carbon ions/sq. cm implanted onto the titanium.
