摘要

NiW alloy coatings were obtained from the acid solution with different concentrations of tungstate.Influences of tungsten contents on mechanical and anticorrosion performance of NiW alloy coatingswere investigated. Tungsten cannot be directly deposited from aqueous solution. However, with theinteraction of nickel ions, tungsten and nickel could be codeposited together considered as inducedcodeposition. The microstructure of NiW alloys coating is Ni17W3 with face center cubic which is a kindof solid solution with nickel as solvent and tungsten as solute. Tungsten atoms occupy the lattice pointsof the nickel atoms and squeeze the nickel atoms to form lattice distortion resulting in the increase ofhardness. NiW alloy coatings with higher tungsten content possess denser and compact nodularstructures that contribute directly to the increase of anticorrosion performance.
