SOLUTION FOR CHEMICAL PRECIPITATION OF COMPOSITE NICKEL COVERS Russian patent published in 2004 - IPC

Abstract RU 2235803 C1

FIELD: metallic covers.

SUBSTANCE: invention relates to applying metallic covers and can be used in electric, chemical industry and in machine engineering. Solution comprises the following components, g/l: nickel chloride, 10-20; sodium fluoride, 2-4; sodium hydroxide, 5-7; sodium hypophosphite, 15-22; succinic acid, 12-20; mercupral, 0.5-1.2, and polymer an aqueous solution, 2-6. As polymer an aqueous solution the invention uses 5% solution of polyvinyl alcohol or 50% suspension of fluoroplast 4MD. Invention provides enhancing wear resistance, corrosion stability in sea water by increasing cover thickness and reducing friction coefficient value.

EFFECT: improved and valuable properties of solution.
