The wear of titanium, titanium alloy, and UHMW polyethylene caused by LTI carbon and Stellite 21.
The comparative wear resistance of a commercially pure titanium (A-70), a titanium alloy (Beta III), and a UHMW polyethylene (Lennite) has been evaluated by employing a test procedure described previously. Either an LTI carbon or a Stellite 21 was the disk material. All material combinations exhibited a low volume wear rate ranging from about 1.2 x 10(-6) to 1.6 x 10(-6) mm3/km. The wear behavior of pure titanium seems to be related not only to its mechanical properties but also to its chemical reactivity with the test environment. A comparison of the current results with earlier data for LTI carbons suggests that LTI carbons may be used as a component material for many artificial joints.
