Optimal alloying component can be determined by selecting an alloying constituent with high oxidation resistance performance, and casting method was utilized for optimizing performance of the rod alloy. 通过分析Cu-Ni基合金高温氧化腐蚀机理确定出抗氧化性能相对较好的合金成分,并采用熔铸方法进一步优化合金导杆的性能。
Du to the different activity of alloying constituent during oxidation process, different elements are beneficiating in particular sector, finally appear stratified phenomenon. 表面氧化层分层的原因是由于氧化过程中不同合金成分的之间作用的活性不同,以致形成不同元素在一定区域的富集,最终出现分层现象。
