SONOCHEMICAL MODIFICATION OF THE NICKEL SURFACE BY THE MOLYBDIC ACID AND PRODUCTS OF ITS POLYCONDENSATION
Abstract
The possibility of sonochemical immobilization of polymolybdic acid on the surface of electrochemically deposited nickel is shown. It is revealed that the thus obtained oxide-hydroxide surface layer is inhomogeneous and involves the products of interaction of molybdic acid oligomers with nickel and MoO3 particles which impart antifriction properties to the modified nickel surface. The possibility of doping the sonochemically obtained molybdenum oxide-hydroxide layer with a corrosion inhibitor (benzotriazole) is demonstrated; such treatment results in a radical (ca. 4-fold) enhancement of corrosion resistance of the galvanic nickel coating.
