摘要

This research studies the effect of implanted tungsten ion on the wear mechanism after ionized tungsten was implanted into material surface as tungsten could improve surface hardening ability and increase wear-resistant property. washer-on-disk wear tests were used to study the change of average friction coefficient and total wear rate. Auger electron spectra (AES) analysis, surface profiler and Vickers hardness tester were utilized to realize the relation among hardness distribution, tungsten ion distribution, and hardened surface. From AES, it indicates that the tungsten had high density distribution when tungsten content is at the depth of 0.25 μm and 0.92 μm, among which the depth of 0.25 μm has the highest density distribution. Vickers hardness test shows that 10 gw load can obtain the highest Hv. The decrease and increase of Vickers hardness value is because tungsten is unevenly distributed. The friction coefficient decreases along with the increase of load under constant rotating speed. The friction coefficient of high rotating speed is smaller than that of low rotating speed. The total wear rate is in proportional to the load under the same turning speed.
