【摘要】 测定了Fe-W非晶镀层在酸溶液中的腐蚀速率,并与SUS304不锈钢进行比较。采用AES和XPS对Fe-W非晶镀层及其在1 mol/LHCl溶液中形成的钝化膜进行了分析。通过测定膜层成份和化学价态,并进行深度剖析,确定钝化膜厚度约700～900nm,钝化膜的化学结构式为WO₃·WO₂OH·nH₂O。更多还原

【Abstract】 The corrosion rate of the amorphous Fe-W deposit was determined in acid medium and was compared with that of SUS 304 stainless steel.The composition of the amorphous Fe-W deposit and the passive film formed on the deposit in 1 mol/L HC1 solution were analyzed by Auger Electron Spectroscopy （AES） and X-ray Photoelectron Spectroscopy （XPS）.The thickness,chemical composition,chemical valence and the element depth profiles of the passive film were obtained.The thickness of the passive film was about 700 to 900 nm.The chemical structural formula for the film was found to be WO₃·WO₂OH·nH₂O.更多还原
