A. Chen et al., A STUDY OF THE RELATIONSHIP BETWEEN WEAR RATE AND NITROGEN CONCENTRATION PROFILE AND APPLICATION TO PLASMA SOURCE ION-IMPLANTED TI-6AL-4V ALLOY, Wear, 165(1), 1993, pp. 97-101
Nitrogen implantation by plasma source ion implantation was conducted
on Ti-6Al-4V alloy. The wear performance was characterized using a pin
-on-disk wear tester and an alpha-step profilometer. Nitrogen concentr
ation depth profiles of implanted samples were studied using a scannin
g Auger microprobe. It is found that the lowest wear rate in the impla
nted zone corresponds to the nitrogen concentration peak. By varying t
he target temperature, the nitrogen concentration profile was engineer
ed to achieve a better wear behavior. The pin-on-disk wear data agree
with the expected result.
