中文摘要	利用电化学极化曲线测量、氧化增重测量、往复式摩擦磨损实验,对分别通过阳极氧化和高压釜氧化生成的2种不同Zr-4合金表面氧化膜的耐腐蚀、耐高温氧化和抗摩擦性能进行测试和对比评价。实验表明,2种氧化膜都有效地改善了Zr-4合金的性能(耐腐蚀,耐高温氧化等),它们对Zr-4合金的改善程度相近。XRD,XPS,RBS,SEM等方法分析表明,阳极氧化膜厚度约1μm,分为疏松水合层和ZrO2致密层2部分,ZrO2由四方相和单斜相组成;高压釜预生膜厚度约0.9μm,分为最外H2O层、疏松水合层和ZrO2致密层3部分,ZrO2只以单斜相存在。研究结果为现行核工业中对Zr-4合金的预处理方法提供了一个新的思路。; The corrosion-resistances, anti-high-temperature air oxidation properties and wearabilities of two different oxide films on Zr-4 alloys were evaluated contrastively by polarization-curve measurement, oxidation mass gain and reciprocating wear test. The two different oxide films were produced by anodic oxidation and autoclaved oxidation methods, respectively. The research showed that the characters of two above-mentioned films were much better than those of the as-received Zr-4 alloy. The improvement levels were similar to each other for both. Furthermore, the anodic Zr-4 oxide film had a thickness about 1 μm, constituted of an external loose hydrate layer and an internal compact oxide layer with m-ZrO2 and t-ZrO2, and the autoclaved Zr-4 oxide film had a thickness about 0.9 μm, composed of a thin water layer, a loose hydrate layer and a compact oxide layer just with m-ZrO2 serially. Therefore, a new research idea can be brought forward by the results in this work on the surface pretreatment of Zr-4 alloys for the current nuclear industry.
