Lubricating-reinforcing composite coatings were successfully prepared on Ti6Al4V using laser-clad Ti6Al4V/Ni60/Ni-MoS2 mixed powders with different Ni-MoS2 contents (25, 35, and 45 wt.%), and their microstructure and tribological properties were studied. The reinforcing phase TiC, Ti2Ni, and the lubricating phase Ti2SC were in situ precipitated while Ti2SC and Ti2Ni formed a mosaic coherent structure within the above three coatings. In the 25 and 45 wt.% Ni-MoS2 coatings, the microstructure distribution uniformity of the coatings was not effectively improved by the Ti2SC-Ti2Ni mosaic structure phase due to the lower or higher content of Ti2SC. In the 35 wt.% Ni-MoS2 coating, the forming quality of the coating was the best due to an appropriate amount of the uniformly distributed Ti2SC-Ti2Ni mosaic structure phase. Furthermore, the microhardness of the coatings gradually decreased as the amount of Ni-MoS2 increased. In the 35 wt.% Ni-MoS2 coating, due to the uniformly and diffusely distributed Ti2SC-Ti2Ni mosaic structure phase, the stable lubricating-reinforcing mosaic structure transfer composite films were formed during the progress of the friction and wear tests, which led to the optimal worn surface evenness and quality, the anti-friction and the wear resistance properties compared with the Ti6Al4V, 25 and 45 wt.% Ni-MoS2 coating.

.A composite process of laser cladding and laser shocking is proposed to prepare the Ti-6Al-4V alloy coating. The structure before laser shocking is flake β phase and acicular martensite α ′ phase precipitated at the grain boundary of the flake β phase. The staggered distribution of acicular martensite α ′ forms a basket structure. After laser shocking, the flake β phase is refined, and the basket structure orientation becomes more complex. In addition, the structure is more uniform and denser. The laser shocking influence depth is about 1.7 mm, the microhardness is increased to 470 to 530 HV0.2, the friction coefficient is decreased to 0.35, the wear amount is decreased by 26%, and the wear form changes from the comprehensive role of abrasive and adhesive wear to abrasive wear.

“…Rare earth is widely used to improve the tribological performances of metals. 13,14 Wan 15 reported that the wear resistance of the ZL107 alloy was markedly improved by adding La 2 O 3 because it can refine silicon phase and help in the uniform silicon distribution, and the morphology of the silicon phase was seen to change from coarse flake to broken rod-like one. Miroslav et al 16 revealed that the tribological behavior of the ZA27 alloy was improved by heat treatment, which resulted in refined microstructure and uniform distribution.…”

Babbitt alloy is a widely used bearing material. In order to improve its thermal and anti-fatigue performance, the combined effect of additive La and heat treatment of tin-Babbitt were studied. The microhardness, wettability, and tribological performances of the Babbitt were first considered. The Babbitt alloy modified with La element (0.1 wt%) was prepared and then heat treatment was carried out (marked by the modified Babbitt). The friction and wear performances of the bare Babbitt, heated Babbitt, and modified Babbitt were conducted by a ball-on-disc tester under oil lubricated condition. The results showed that the microstructure of the modified Babbitt alloy was homogeneous. The cubic phase of SnSb intermetallic was refined and the SnSb cubes were also passivated. The microhardness of the modified Babbitt increased from 24.67 Hv to 37.84 Hv and wettability was improved with the addition La and heat treatment. Therefore, the anti-wear performance of the Babbitt was improved. The modified Babbitt alloy is observed to resist the instant scratching from the journal.
