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样的显微结构,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Ni2O3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。“,”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. Ni2O3 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 tellurium-free alloy.
