摘要： 低磷镀层（ＬＰ）在碱性和中性盐水条件下的耐蚀性较高磷镀层好。当ＬＰ镀层在３５０℃下热处理１ｈ后，镀层的显微硬度从４５４Ｈｖ增加到８９０Ｈｖ。差热分析研究发现，在３４１．６℃和４０６．２℃有两个放热峰，分别对应于新相Ｎｉ５Ｐ２和Ｎｉ３Ｐ的形成。利用Ｘ射线衍射对镀层的结构进行分析，发现该镀层由非常细的微晶构成。

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.
Key words: Electroless nickel, Low phosphorus, X-ray diffraction, Differential thermal analysis.
