| 摘 要： | 研究了掺杂(0.5%~2.5%) Cu元素对TA10合金的微观组织、力学性能及腐蚀性能的影响,采用扫描电子显微镜(SEM)、金相显微镜(OM)研究合金的微观组织,并用XRD进行物相分析;采用电化学腐蚀、静态浸泡腐蚀试验研究合金的腐蚀性能。选出最佳合金成分,并通过原子力显微镜(AFM)对其做进一步分析。结果表明,随着Cu元素含量的增加,TA10合金基体组织被不断细化,添加2.5% Cu时,该合金的硬度值达到最大。Cu含量在1.0%~2.0%之间,合金的耐腐蚀性能较好。含Cu为0.5%的合金耐腐蚀性能优异。

| Abstract: | The effects of (0.5%~2.5%, w) Cu addition on the microstructure, mechanical property and corrosion behavior of TA10-based alloys are studied. Scanning electron microscopy (SEM) and optical microscopy (OM) are used to study the microstructure of the alloys, and the X-ray diffraction (XRD) is adopted to identify the phase composition. The electrochemical measurements and the static immersion tests are employed to study the corrosion performances of the alloys. After obtaining the alloy with the optimal chemical compositions, its corroded surface morphology is observed by the atomic force microscope (AFM). Results signify that with the increase of Cu content, the matrix structure of TA10 alloy is continuously refined. When the Cu addition is 2.5%, the hardness of the alloy is the maximum. When the Cu addition is in the range of 1.5%~2.0%, the alloy has good corrosion resistance. The alloy with 0.5% Cu presents the best corrosion resistance. |
