Abstract
The low phosphorus coatings(LP) had superior corrosion resistence to that of high phosphorus(HP) in alkaline and neutral NaCl sulutions. The microhardness of the coatings increaed from 454 Hv to 890 Hv when they were heated at 350℃ for one hour. Two exothermic peaks were observed at 341. 6℃and 406. 2℃, which respectively corresponded to form the new phases Ni_5P_2 and Ni_3P in the differential thermal analysis. The atomic structure of as-deposited coatings in the terms of X-ray diffraction had confirmed that the coatings coasisted of extremely fine crystallites.
