Abstract The Ni-P electroless coatings with different P contents were prepared by varying the compositions of electroless plating bath,and the P contents were determined using X-ray energy disperse spectrum.The effect of Ni-P coating on SCC of 304L stel welding joint in boiling 42% MgCl2 solution and in 5% HCl solution at 25℃ was investigated by means of slow strain rate tensile test and constant load tensile test.Results showed that a perfect Ni-P electroless coating could effectively prevent substrate material from SCC at low stress.Under higher stress（σ＞σs） or in the presence of defects or cracks in the coating,SCC originated from defects or cracks in the base material under the coating.The coating did not provide electrochemical protection to the substrate bacause of the relative relationship of corrosion potentials for the coating and the substrate.

Key words: Ni-P electroless coating stress corrosion 304L steel welding joint
