Abstract:To improve the deposition rate and quality of nanocrystalline nickel coatings, a method involving movable, flexible friction, jet electrodeposition (MFFJE) was proposed in this paper. The effects of cathode scanning speed and current density on electrodeposited nickel coatings prepared by MFFJE were investigated. Compared with traditional jet electrodeposition, the results showed that MFFJE exerted remarkable effects, improving the deposition rate and quality of nickel coatings, and, when the cathode scanning speed was 1000mm min(-1), the coating surface morphology was best. The maximum processing current density of nickel plating was more than 250 Adm(-2). The grain size was decreased to 11.7 nm, hardness increased to 546 HV, and coating corrosion resistance significantly improved.
