摘要：

Nanocrystalline nickel was prepared by friction aided jet electrodeposition and traditional jet electrodeposition. The structure of two Nickel deposition layers was studied by TEM, and the corrosion behavior in 3.5wt%NaCl solution and 1 mol/LH2SO4 solution was studied by electrochemical polarization method. The results show that nano-crystalline nickel prepared by friction aided jet electrodeposition has a compact structure and an average grain size of 9.77 nm. In two corrosion solutions, the electrochemical corrosion resistance of nanocrystalline nickel prepared by friction aided jet electrodeposition can be both better than that prepared by traditional jet electrodeposition. Only nanocrystalline nickel prepared by friction aided jet electrodeposition generates passive film in the corrosion process. The grain size and micro-defects are two important factors that affect the corrosion resistance of nanocrystalline nickel
