Surface molybdenizing on titanium by halide-activated pack cementation

Microstructural Evolution in Chroming Coatings Friction Pairs under Dry Sliding Test Conditions

“…The chroming and nonchroming T10 steel discs have hardness of about 590 HB and 180 HB ( , 0.05 m to 0.33 m), respectively. The conventional powder pack cementation method [9,10] was applied to produce the chroming coating on T10 steel discs. The operation of the powder filling process is 1273 K and lasts 24 hours.…”

Effect of Cr alloying on friction and wear of sputter-deposited nanocrystalline (MoxCr1−x)5Si3 films

“…1(a)) shows that the diffusion layer is a composite of b-Ti, a 00 and a 0 phases. Because the dominant diffusion element in Mo 5 Si 3 phase is Mo [28], Mo element diffuses inwards into interface between the deposited layer and substrate, leading to the phase transformation of b/a 00 /a 0 , which occurs from outside to inside for the different Mo contents in the diffusion layer [29]. Combining the XRD results and EDS analysis, conclusions can be made that according to the different Mo content, Mo diffusion layer may be subdivided into b phase layer with high Mo content (>10 wt.%) and a 00 /a 0 layer with low Mo content (<10 wt.%), as shown in Fig.…”

High temperature friction and wear behaviour of sputter-deposited nanocrystalline (MoxCr1−x)5Si3 films by a double cathode glow discharge technique

“…1) shows that the diffusion layer is a composite of ␤-Ti, ␣ and ␣ phases. Because the dominant diffusion element in Mo 5 Si 3 phase is Mo [25], Mo element diffuses inwards into interface between the deposited layer and substrate, leading to the phase transformation of ␤ → ␣ → ␣ , which occurs from outside to inside for the different Mo contents in the diffusion layer [26]. Combining the XRD results and EDS anal- ysis, conclusions can be made that according to the different Mo contents, Mo diffusion layer may be subdivided into ␤ phase layer with high Mo content (>10 wt.%) and ␣ /␣ layer with low Mo content (<10 wt.%), as shown in Fig.…”
