电真空镍带我国早在六十年代初就开始试制,但由于一直存在烧氢时有变色和在高温真空条件下有严重的蒸发现象两大问题,至今仍需要从国外进口。为了解决国产镍材质量问题,上海有色金属研究所在南京七七四厂配合下,从理论和实验分析二个方面深入全面研究了导致器件脉冲中断的材料原因,认为镍材中镁量过高会引起蒸发,而烧氢变色是由于铝硅、镁、钛、钙等元素与氢气中的水蒸汽作用,生成了氧化物所致。该所采用真空熔炼和真空热处理,严格控制杂
Electro vacuum nickel belt started trial production as early as the early 1960s in our country. However, there are still two major problems of discoloration when burning hydrogen and serious evaporation phenomenon under high temperature and vacuum. So far, it still needs to be imported from abroad. In order to solve the problem of the quality of domestic nickel, Shanghai Institute of Nonferrous Metal, with the cooperation of Nanjing No.744 Factory, deeply and comprehensively studied the material causes of the device pulse interruption from two aspects of theoretical and experimental analysis. It is concluded that the content of magnesium in nickel is too high Will cause evaporation, while burning hydrogen discoloration is due to aluminum silicon, magnesium, titanium, calcium and other elements in the role of hydrogen and water vapor generated oxide. The use of vacuum melting and vacuum heat treatment, strict control Miscellaneous
