Abstract A nickel-phosphor coating was prepared on the surface of 1Cr18Ni9Ti stainless steel by electroless plating. The coating was so uniform and dense that it had no surface defects. The structure of the coating was amorphous in nature checked by X-ray diffraction. By dynamic potential polarization test, it was shown that the free corrosion potential of the coating approached -0.1 V(vs. SCE) and it nearly 0.2V larger than that of stainless steel (-0.31 V), and it had much better anti-corrosion ability than stainless steel and can protect the substrate effectively.
