Description
Summary:The influence of characteristics of ligands and nickel complex compounds on the rate of the autocatalytic (chemical) deposition of nickel–phosphorus coating and the phosphorus content is considered. It has been established that the charge and complex of the ligand have the highest effect on the rate of process, and charge number and stability of the complex ion have the highest effect on the content of phosphorus in the coating. Mathematical models describing the relationship between the deposition rate, the composition of coatings, and the corresponding ligand parameters are obtained. Recommendations for the selection of the ligand composition of solutions for the chemical deposition of nickel–phosphorus alloy are proposed.
