“…In this context, co-deposition of several elements such as copper, cobalt, tin and cerium has been carried out to modify the original properties of regular Ni-P coatings [7][8][9][10] . Properties such as thermal stability, corrosion resistance, electronic conductivity and wear resistance can be improved by properly controlling bath conditions and composition 11,12 .…”

Ternary Ni-W-P films were produced by electroless deposition using baths with different tungsten concentrations. After deposition, the coated surfaces were annealed at 400°C for 1h. Surface morphology and film composition in the as-plated condition were assessed by SEM and EDS analyses, respectively. The crystalline phases after annealing were investigated by X-ray diffraction (XRD). Nanoindentation tests were performed to assess the mechanical properties of the deposited films. Surface roughness was determined by confocal laser scanning microscopy (CLSM). Friction coefficient was evaluated by reciprocating were tests in a nanotribometer. The corrosion behavior was evaluated by potentiodynamic polarization curves. The results showed that the surface morphology, crystallization behavior and corrosion resistance were affected by the tungsten content in the film. The best corrosion performance was obtained for the ternary films after annealing. Hardness, surface roughness and friction coefficient were dependent of the tungsten concentration in the film.

It was reported that the ternary Ni-Sn-P coating exhibited better corrosion resistance than Ni-P coating when the electrochemical analysis was tested in 10% HCl solution, 44) in which the ternary Ni-Sn-P coating contained 2.48 mass% tin. From these literature, it can be seen that the reports about corrosion resistance of Ni-P-Sn coating is not consistent.…”

In this study, the ternary Ni-P-Sn alloy coatings were prepared using electroless plating, and the effect of tin element on amorphous formation and anticorrosive properties of deposits in different corrosion medium were investigated. The different tin contents in deposits could be obtained by adjusting the amount of NaSnO 3 Á3H 2 O in plating bath. The X-ray results indicate that the small amount of tin addition can improve the formability of the amorphous phase. At the same time, the hardness of deposit decreases and the crystalline temperature shifts to lower temperature with increasing amount of Sn. The electrochemical corrosive experiments of deposits resulted that the addition tin improves the anticorrosion property in 3.5 mass% NaCl solution, but reduces the anticorrosion ability in sulfuric acid solution.

“…The porosity test, acid immersion test and electrochemical measurements (Table 3) reveal that the presence of tungsten and the dense and pore-free microstructure make the coating suitable for corrosion resistance applications. The same researchers published a paper on electroless ternary Ni-Sn-P (Zhang et al, 2008).…”
