1表面施加含稀土氧化物薄膜对Fe25Cr高温氧化的“活性元素效应”显示文摘研究了表面施加含有不同量Y2O3的Cr2O3和Al2O3薄膜对Cr2O3形成合金Fe25Cr在1000℃、104PaO2环境中高温氧化的作用.结果发现含Y氧化物薄膜明显降低了Cr2O3层的生长速度,而且含Y复合氧化物薄膜的作用大于单一Y2O3薄膜.此时,Cr2O3层表面形貌发生了较大的变化.间接证据表明Cr2O3的生长机制由阳离子向外扩散为主转变为阴离子向内扩散为主.通过表面施加含Y的氧化物薄膜产生了全面的“活性元素效应”齐慧滨 D.G.Lees 何业东 1999腐蚀科学与防护技术1999,11,4:3
2Evidence for Vacancy Injection during the Oxidation of Iron显示文摘Iron discs have been oxidised at 890℃on one side only,with the other side protected by an inert gas.The scale-metal adhesion was very good.Initially,scale-metal adhesion was maintained by the scale relaxing towards the metal but after a time which depended upon the initial metal thickness,oxide relaxation ceased and the inert face moved towards the scale-metal interface.When the face which was normally inert was coveredwith a non-growing oxide layer,the scale-metal adhesion deteriorated.The results show that vacancies which were produced by oxidation were annihilated within the metal,that the inert face played a part and that the scale-metal interface is not a good sink for vacancies.D.G.LEES R.FRANCIS 2009中国腐蚀与防护学报2009,29,4:0
