“…These conditions make the requirements for the wear resistance of the gear more demanding. In addition to improving the wear resistance by solid-solution precipitation of second-phase particles on the substrate via microalloying [5], surface modification by deposition or diffusion coating, such as plasma spraying [6,7], physical or chemical vapor deposition (PVD or CVD) [8,9], pulsed laser or laser cladding treatment [10,11], and thermo-diffusion coating [12,13] are considered effective ways to improve the wear resistance and meet the growing demand of conventional gear steels.…”

Cr-coating was deposited on AISI 5140 steel by electro brush-plating, followed by annealing treatment at different temperatures, from 300 to 1100 • C. The microstructure evolution of the Cr-coating was characterized by backscattered electron imaging (BSEI) and energy dispersive spectrometry (EDS). The results show that the brush-plated sample has a nodular shaped microstructure, which is very stable at 300 • C of annealing. At 500 • C of annealing, the constitution of the microstructure changes from nodules to grains. As the annealing temperature further increases, the grains grow significantly. When the temperature reaches 1100 • C, a Cr-Fe solid-solution layer is formed within the original pure Cr-coatings. With increasing annealing temperature, the number of micro-cracks in the coating increases first and then decreases, reaching a maximum at 500 • C. The hardness and wear-resistance of the coating are improved when the annealing temperature increases to 1100 • C, owing to the decrease of micro-cracks that formed during brush-plating.
