THE ELECTROSEDIMENTATION OF NICKEL FROM THE FORMIATE-CHLORIDE ELECTROLYTE

The process of the electrosedimentation of the nickel coatings has been studied. The work is aimed at studying the laws of the electric sedimentation of nickel from the formiate-chloride electrolytes and peculiarities of the mass-transfer to the cathode in them; at studying some physico-chemical properties of nickel coatings and interconnections between the properties of nickel and its structure. For the first time, the formiate-chloride electrolytes of nickel-plating have been studied. The influence of the complex-formation and educing of hydrogen to be combined with nickel on the mass-transfer in the solution of the nickel formiate has been considered. The compositions of the formiate-chloride electrolytes have been recommended for receiving the nickel coatings with higher microsolidness, with the reduced interbal stresses, with high protective ability. The electrolyte has been tested in the large laboratory unit.
