“…According to previous studies, the mechanical properties of Ni-Mo coatings could be regulated by Mo [15], where the coating becomes soft with the decrease of Mo content. However, substantial stress is accompanied when the Mo content is high, and cracks initiate easily, compromising the coating's performance [16][17][18][19].…”

To improve the wear resistance of the metallic components, Ni–Mo-TiN composite coating was prepared via pulsed electrodeposition. The microstructure, mechanical, and tribological characteristics were compared to those of Ni–Mo coating. The results revealed that the addition of TiN reduced internal stress within the Ni-Mo-TiN composite coating and mitigated the propensity for crack formation during the coating preparation and friction testing. Grooves and pits are observed on Ni-Mo coating, indicating a typical feature of fatigue wear. Owing to the synergistic effect of the tough Ni-Mo matrix and hard TiN particles, the Ni-Mo-TiN coating is characterized by micro-cutting and a superior wear resistance was achieved. Based on the experimental results, the effect of TiN on the microstructure, mechanical properties, and wear resistance of the Ni-Mo coating was discussed.

Currently, sodium citrate is the most used complexing agent for electrodeposition of Ni-Mo coatings, especially for studying the effect of bath temperature and current density on the proprieties of Ni-Mo coatings. This study evaluates the influence of the concentrations of nickel sulphate and sodium molybdate on the electrodeposition of Ni-Mo alloys in baths using tartrate as a complexing agent. Electrodepositions were carried out in a two-electrode cell. A 3 2 complete factorial design of experiments along with response surface methodology (RSM) was used for the optimization of bath variables for electrodeposition of Ni-Mo alloys. The coatings obtained were characterized in terms of chemical composition and surface morphology. The chemical composition of the coatings was most influenced by the sodium molybdate concentration. Ni-Mo coatings of good quality were obtained in potassium-sodium tartrate baths with Mo content in the range 18-44 wt%; some results present even higher Mo content than coatings obtained from citrate baths. The coating with the highest Mo content was deposited from the bath with a concentration ratio of nickel sulphate to sodium molybdate of 1:1. Surface morphology varied according to chemical composition, and microcracks were observed for the coating with 41 wt% Mo, for which scanning electron microscopy (SEM) images also show the presence of nodules. The most homogeneous coating surface was obtained at a concentration ratio of nickel sulphate to sodium molybdate of 10:3. X-ray diffraction analyses have shown that all coatings obtained in this work are amorphous.
