pitting gears can more readily undergo micropitting wear resulting in greater gear tooth profile geometry modification and providing some stress relief As Figures 1–4 indicate the micropitting wear band in the pitting gears is narrow and a shoulder is quickly built toward the edge of the micropitting wear band With such a shoulder

The micro-hardness of the cladding coatings increased by 2–4 times than that of the Ti-6Al-4V substrate and the maximum hardness reached 1349 HV Under the same dry sliding wear condition the wear resistance of the WC-25Co coatings was significantly improved and increased by 15 7–34 1 times compared with the substrate
