SOLUTION FOR CHEMICAL PRECIPITATION OF COMPOSITE NICKEL-PHOSPHORUS COATINGS Russian patent published in 2014 - IPC C23C18/36

Abstract RU 2531219 C1

FIELD: chemistry.

SUBSTANCE: invention relates to the field of application of composite nickel-phosphorus coatings on steel details by a method of chemical precipitation A solution contains, g/l: nickel dichloride 10-15, succinic acid 12-15, sodium fluoride 2-3, sodium hydroxide 4-6, sodium hypophosphite 17-20, copper-intercalated potassium polytitanate 6-10, remaining part - water.

EFFECT: invention makes it possible to obtain composite nickel-phosphorus coatings, which have an increased wear resistance and low friction coefficient, as well as makes it possible to increase the strength of adhesion of the coating with the base.
