“…For the deposition quality, the RE compounds firstly reduced the concentration of free hydrogen in electroplating solution by lowering the hydrogen separation pressure, the diffusion coefficient, and the activity of hydrogen [12,31]. Besides, RE ions had a strong chemical affinity for hydrogen due to the unique electronic shell structure, which absorbed and dissolved a significant quantity of hydrogens to form hydride [12,20,34]. Due to the RE compounds' ability to prevent hydrogen penetration and precipitation on the Cu-cathode surface, the surface pits in figure 2(a) were relatively relieved.…”

For optimizing the microstructure and performance of Ni–electroplating film, the soluble rare–earth (RE) compounds CeCl3 or LaCl3 were introduced, which were electrodeposited on Cu substrate by direct current (DC) and pulse current (PC) methods, respectively. The surface characteristics of morphology, composition, and phase of obtained different deposits were investigated, and the relationship between the structure and the performance of internal stress, hardness, and electrochemical responses was discussed. The results show that both RE compounds were conducive to eliminating the surface pits by inhibiting the hydrogen evolution reaction, while did not co–deposit into the Ni film. Moreover, the preferred orientation of Ni (111) crystalline plane was altered into Ni (200) by LaCl3, and its combination with PC–electrodeposition further had a better grain refinement effect than CeCl3. Due to the formation of a relatively dense and fine deposit, the PC–electrodeposited Ni/LaCl3 film exhibited the highest hardness of 320 HV, lowest tensile stress of 55 MPa, and best electrochemical passivation protection, which effectively improved the comprehensive performance of Ni film and demonstrated a good prospect for industrial applications.
