用电沉积法获得的含9～12%磷的镍-磷合金层,为非晶态的均相结构,具有十分优越的耐蚀性能。在常温下耐盐酸腐蚀的性能优于哈氏合金;对非氧化性氯化物的耐蚀性可与金属钛相媲美;耐各种温度与浓度的热烧碱的腐蚀性能优于金属镍;对高温氟化物的耐蚀性能与蒙乃尔合金相当;对多种有机酸及大部分介质的耐蚀性远远超过常用的奥氏体不锈钢。
The nickel-phosphorus alloy layer containing 9-12% phosphorus obtained by electrodeposition is an amorphous homogeneous structure with a very good corrosion resistance. Corrosion resistance at room temperature is better than that of Hastelloy; Corrosion resistance of non-oxidizing chlorides is comparable to that of titanium; Resistance to hot caustic soda at various temperatures and concentrations is superior to that of metallic nickel; Fluoride corrosion resistance and Monel comparable; a variety of organic acids and most of the corrosion resistance of the medium far beyond the commonly used austenitic stainless steel.
