机理和氧化层剥落机理进行研究表明：合金氧化增重随温度升高明显增加，至1050℃反而降低；600℃的氧化膜主要为TiO2和V2O5，高于700℃氧化，因V2O5的挥发，氧化膜主要为TiO2，随温度升高，氧化物晶粒粗化，氧化膜疏松多孔，与基体黏附性降低，不低于900℃时开裂和剥落，不低于800℃氧化，氧化层疏松处还存在SiO化合物，温度升高，SiO数量增多，由圆球形变为星形，至1050℃随氧化层剥落而消失；剥落后的基体氧化层仍为疏松状，有不连续分布的Cr2O3膜存在。同时还分析了Ti40合金不抗氧化的原因及氧化机理，提出了氧化机理模型。在分析氧化膜内应力产生及内应力释放机制基础上，提出了Ti40合金氧化层开裂、剥落机理。","authors":[{"authorName":"赵永庆","id":"fd493a98-c55b-4131-83e5-9bfeb0023b09","originalAuthorName":"赵永庆"},{"authorName":"曲恒磊","id":"80fb9ea5-d2c3-4f5e-afb8-b16b4d4d0276","originalAuthorName":"曲恒磊"},{"authorName":"朱康英","id":"aac71b77-5840-4373-8a3f-c5c99389a489","originalAuthorName":"朱康英"},{"authorName":"吴欢","id":"6f64690e-e1bb-459b-997c-1fe62d53a2e7","originalAuthorName":"吴欢"},{"authorName":"周廉","id":"13035b67-02c3-4733-a6de-d308d6fdfc93","originalAuthorName":"周廉"}],"doi":"","fpage":"35","id":"332f00b1-a8ee-40c3-bd9c-fc27abf252f2","issue":"1","journal":{"abbrevTitle":"XYJSCLYGC","coverImgSrc":"journal/img/cover/XYJSCLYGC.jpg","id":"69","issnPpub":"1002-185X","publisherId":"XYJSCLYGC","title":"稀有金属材料与工程"},"keywords":[{"id":"2a17df71-a5eb-4c59-9e70-26921515cade","keyword":"Ti40合金","originalKeyword":"Ti40合金"},{"id":"6343a60c-79c8-44d0-8545-c9d229bd4b31","keyword":"阻燃钛合金","originalKeyword":"阻燃钛合金"},{"id":"9ae47407-99af-4b1d-8b84-a0852d85cd2e","keyword":"氧化机理","originalKeyword":"氧化机理"},{"id":"aa56f875-e49c-49ad-8d57-29f150a0147e","keyword":"剥落机理","originalKeyword":"剥落机理"}],"language":"zh","publisherId":"xyjsclygc200101010","title":"高度稳定化β型阻燃钛合金Ti40的氧化和氧化层剥落机理","volume":"30","year":"2001"},{"abstractinfo":"高锰钢铁路辙叉在使用过程中因心轨表面龟裂剥落而提前失效,对其进行了扫描电镜观察和能谱仪测试分析.结果表明:断口中的夹杂物为Al2O3或[Al2O3]·(CaO)x等;在表面裂纹的断口微观组织中有大量的致密疲劳辉纹和泥状腐蚀形貌,次表面裂纹断口也有疲劳辉纹,表明辙叉表面的剥落掉块为表面的腐蚀疲劳和次表面的接触疲劳所致.疲劳裂纹往往从氧化铝、氧化钙等颗粒状夹杂物或组织不均匀处萌生,表面裂纹与切应力成锐角向表层下扩展,次表面裂纹斜向表面扩展,当表面裂纹与次表面裂纹相互连接时,被裂纹包围的金属块即产生剥落,形成剥落坑.","authors":[{"authorName":"张敏","id":"ccf2502d-0e5c-4761-bc63-bdde654bedb1","originalAuthorName":"张敏"},{"authorName":"王为波","id":"2df2a717-f736-4bfa-b5a8-0ee3846caba8","originalAuthorName":"王为波"},{"authorName":"安强","id":"9bd1b0da-4381-4f9a-9652-9ab055b3951b","originalAuthorName":"安强"},{"authorName":"周永欣","id":"6ea58ab5-fd80-4199-9d9f-22c6cf1246bf","originalAuthorName":"周永欣"},{"authorName":"吕振林","id":"a7e094ff-e51f-42c7-8f68-412c1ec35497","originalAuthorName":"吕振林"}],"doi":"10.3969/j.issn.1000-3738.2005.09.020","fpage":"64","id":"3e76311f-4051-48ad-b70e-072227a76672","issue":"9","journal":{"abbrevTitle":"JXGCCL","coverImgSrc":"journal/img/cover/JXGCCL.jpg","id":"45","issnPpub":"1000-3738","publisherId":"JXGCCL","title":"机械工程材料"},"keywords":[{"id":"be6ddb3c-dab2-4475-b67f-f61d0afe1dda","keyword":"铁路辙叉","originalKeyword":"铁路辙叉"},{"id":"4718fe75-87a4-44dd-a55d-f8261ad6580d","keyword":"龟裂剥落","originalKeyword":"龟裂剥落"},{"id":"2822647a-67bf-4101-87f8-fb1fd5928f12","keyword":"腐蚀疲劳","originalKeyword":"腐蚀疲劳"},{"id":"fac2edd3-1377-4d13-a486-c21c6dc7b2ee","keyword":"接触疲劳","originalKeyword":"接触疲劳"}],"language":"zh","publisherId":"jxgccl200509020","title":"高锰钢铁路辙叉表面龟裂剥落机理分析","volume":"29","year":"2005"},{"abstractinfo":"采用原位腐蚀试验、静态失重试验、浸泡试验研究了2219铝合金搅拌摩擦焊接接头的剥落腐蚀行为与机理.结果表明:2219铝合金搅拌摩擦焊焊缝腐蚀速率比母材小,焊缝的抗腐蚀性提高;腐蚀从局部点蚀开始,起源于第二相粒子与其边缘的铝基体,第二相粒子作阴极;原位腐蚀2h后焊核与热机影响区发生晶间腐蚀,母材发生严重的点蚀;均匀分布的第二相粒子与细小的等轴晶组织是焊核区剥落腐蚀敏感性降低的主要原因.","authors":[{"authorName":"张华","id":"a2101d83-53ec-4568-aab5-9d4acde99fcf","originalAuthorName":"张华"},{"authorName":"孙大同","id":"23e1afca-7d3a-4f9c-8697-7f048e5a8b99","originalAuthorName":"孙大同"},{"authorName":"张贺","id":"26b21217-3afe-490b-a225-c478db8471b8","originalAuthorName":"张贺"},{"authorName":"马芳芳","id":"82f2a3c3-8ad8-41df-9392-e389ed462168","originalAuthorName":"马芳芳"},{"authorName":"黄继华","id":"e2a59060-10f7-4cec-b5d6-c237096b09fe","originalAuthorName":"黄继华"}],"doi":"","fpage":"103","id":"a84e5cb8-6421-44f7-a60f-c38c147b2a4b","issue":"1","journal":{"abbrevTitle":"XYJSCLYGC","coverImgSrc":"journal/img/cover/XYJSCLYGC.jpg","id":"69","issnPpub":"1002-185X","publisherId":"XYJSCLYGC","title":"稀有金属材料与工程"},"keywords":[{"id":"1329dc53-d087-4691-a356-ce8d8e5459af","keyword":"2219铝合金","originalKeyword":"2219铝合金"},{"id":"b5c6cffc-21b5-449c-92db-b4d3bf898003","keyword":"搅拌摩擦焊","originalKeyword":"搅拌摩擦焊"},{"id":"afad188c-ba4d-4995-8ee5-b29357fa5611","keyword":"剥落腐蚀","originalKeyword":"剥落腐蚀"},{"id":"90ad1313-9c1c-4a8f-a26b-851adb364c72","keyword":"晶间腐蚀","originalKeyword":"晶间腐蚀"},{"id":"4158c9c8-77a3-42ae-a5db-da7ac2d8722b","keyword":"原位腐蚀","originalKeyword":"原位腐蚀"}],"language":"zh","publisherId":"xyjsclygc201501020","title":"2219铝合金搅拌摩擦焊接接头剥落腐蚀机理","volume":"44","year":"2015"},{"abstractinfo":"热轧态奥氏体钢4Cr14Ni14W2Mo氮化层的剥落倾向与接受氮化的表面在原棒材的取向有关。发现本试验钢料的晶粒中存在大体上呈平行排列的位错墙,而且不同晶粒的位错墙也大体上呈同向顺列的排布。当接受氮化的表面与这种位错墙近于平行时,在该表面上将形成易于剥落的厚的白亮氮化层。","authors":[{"authorName":"孙旭东","id":"74b147f6-a91c-4d77-8e81-10b76bccb512","originalAuthorName":"孙旭东"},{"authorName":"李见","id":"adfc018b-8f87-4ae2-9cdc-c550a243fca8","originalAuthorName":"李见"}],"categoryName":"|","doi":"","fpage":"71","id":"36f953d5-d1f2-4634-a385-f1c37b4ad48b","issue":"2","journal":{"abbrevTitle":"JSXB","coverImgSrc":"journal/img/co
