| 摘 要： | 利用粉末冶金技术制备新型Te-Ni-Cr合金材料,在人造海水中进行全浸腐蚀试验,通过金相组织观察、扫描电镜对表面腐蚀形貌的观察、表面EDS及XRD对腐蚀产物的分析,研究了Te-Ni-Cr合金的耐蚀性能。结果表明,碲元素的加入改变了试祥的显微结构,形成黑灰色突起的骨骼状组织,对整个合金的表面起支撑保护作用;经XRD分析确定腐蚀产物为Ni_2O_3和铁的氧化物,计算腐蚀速率得到,Te-Ni-Cr合金的耐蚀性较未加碲的有所提高。

| Abstract: | A new Te-Ni-Cr alloys were prepared by powder metallurgy technology and the corrosion resistance of Te-Ni-Cr alloys were studied by OM,SEM,EDS and XRD in the 3.5%sodium chlorine solution.The results show that the microstructure of the alloys are changed by Te.There are bone-like dark gray structure on the surface of the alloy,playing protective role.Ni_2O_3 and iron oxide were determined by the analysis of XRD.The calculated corrosion rate shows that Te-Ni-Cr alloy increases the corrosion resistance than te... |
