AI Technical Summary
Existing complexing agents have poor adaptability in platinum group metal electroplating solutions with different compositions, resulting in unstable coating quality, and the corrosion of artificial sweat affects the appearance and performance of the equipment.
By using complexing agent compositions with specific molar ratios, such as diethylenetriamine, aminosulfonic acid, aminoacetic acid, N-n-propylpyridine chloride, and 1-methyl-3-butylimidazole chloride, combined with appropriate inorganic acids and platinum group metal salt concentrates, and controlling electroplating parameters such as temperature and current density, stable metal complex ions are formed, thereby improving the deposition rate and coating quality.
It expands the application range of complexing agents, improves the stability and wear resistance of coatings, reduces the internal stress of platinum group metal coatings, significantly improves application value, and results in smooth and bright coatings with significantly enhanced corrosion resistance.
