摘要
Electroless nickel (EN) coatings varying in occluded phosphorus were characterized using scanning tunneling (STM), electron microscopy (EM) and X-ray diffraction (XRD). Low-phosphorus (1 to 3 percent) EN coatings were crystalline and exhibited rounded mounds surrounded by fairly deep crevices. Medium- (4 to 7 percent) and high-(more than 9 percent) phosphorus deposits were generally amorphous and smooth. The effect of a small applied current on the structure was also determined.
