摘要: In this study, the internal stress of Ni coating electroplated in supercritical-CO2 (Sc-CO2) mixed Watts bath was investigated with a focus on effects plating parameters and additives. Both stresses coatings their corresponding microstructures were examined. A relationship is found that inversely proportional to its grain size Ni{200}/Ni{111} peak fraction measured X-ray diffraction pattern. The smaller size, accompanied higher Ni{111} intensity, resulted coating, vice versa. proposed theoretical model, which took both preferred crystalline orientation into account, correlated closely experimental results stress. As result, presence surfactant Sc-CO2 electrolyte increased coating. However, reduction made possible by varying four factors: raising current density, increasing temperature, lowering pressure, addition saccharin electrolyte. comparison plated conventional method also discussed study.
