Effect of the microstructure on the anti-fouling property of the electroless Ni-P coating

The Ni-P coatings with different contents of nanocrystalline phase were prepared by electroless plating, Crystallization fouling adhering experiments indicated that these electroless Ni-P coatings have better antifouling property than that of un-coated sample. The effect of microstructure on anti-fouling property of Ni-P coatings is that the adhering amount of crystallization fouling increased with the increasing of nanocrystalline phase. It is considered that the degree of crystallization fouling adhesion is related to the corrosion resistance of the sample. The amorphous Ni-P coating with excellent corrosion resistance is not easy to form transitional interface connecting fouling and matrix. (C) 2008 Elsevier B.V. All rights reserved.
