Abstract:
The effects of the concentration of NiSO4·6H2O, NaH2PO2·H2O, compound ligands and rare elements ( RE) on the bath solution were researched respectively. The results show that the optimal formulae are NiSO4·6H2O- 35 g / L, NaH2PO2· H2O- 30 g/ L and La( NO3) 31. 7-mg/ L. The coating obtained via optimal bath solution and conditions secure an relatively better stability and a higher increase of coat weight, with its surface having a metallic luster and higher density and excellent corrosion resistance.
