As molybdenum-containing alloys show high hardness, excellent wear and corrosion resistance and catalytic hydrogen evolution performance, they have been extensively used as wear and corrosion resistant coatings and electrode materials in the fields of metal rotection, hydrogen production from electrolytic water. Due to its advantages such as fast speed, dense coating and abundant products, electrodeposition has become one of the dominant technologies for the preparation of molybdenum containing alloys. In the early years, electrodeposition was used to prepare merely binary molybdenum alloys, and its process and mechanism were deeply studied. However, the properties of binary molybdenum alloys were limited, which could not easily be improved by adjusting the process parameters. There's a tendency in recent years to improve the properties of binary molybdenum alloys by adding other elements to prepare multicomponent molybdenum alloys or / and adding particles to prepare particle doping molybdenum alloys. Elements of C, Fe, P, W and Cr have the positive effect on different properties of the molybdenum-containing alloys. C, Zn, Sn, S, Fe and P in the alloys appear to result in improving the catalytic hydrogen evolution performance with the mechanism of a synergistic effect among the metallic elements. W, Cr and P achieve an improvement on the microhardness, wear resistance and corrosion resistance of the alloys due to the change of structure and lattice distortion. For particle doping, ZrO2 , TiO2 , SiC, TiN in the alloys are appropriate to improve the microhardness, wear resistance and corrosion resistance, because they are dispersed in the alloy matrix, refining grains and hindering dislocation movement. Recently, magnetic field and ultrasonic technique are more and more introduced in the electrodeposition process of the particle doping molybdenum alloys to improve both the alloy performance and current efficiency. This review offers a retrospection of the research efforts with respect to electrodeposition of molybdenum containing alloys, provides elaborate descriptions of the electrodeposition technology,mechanism and alloy properties of binary molybdenum-containing alloys such as Ni-Mo and Co-Mo, multicomponent molybdenum-containing alloys such as Ni-Mo-Zn and Co-Mo-P, and particle doping molybdenum-containing alloys such as Ni-Mo-ZrO2 and Co-Mo-TiO2 , and sums up the similarities and differences of alloying elements and particle on improving properties. We then show solicitude for the problems of the molybdenum containing alloys. We are confident that the molybdenum-containing alloys have a bright future in the development and innovation of better properties and wider applications. © 2023 Cailiao Daobaoshe/ Materials Review.
