金银镍复合管的研究

Study of Gold-Silver-Nickel Tube

本文介绍了一种生产双金属管的新方法,即将贵金属管与一般金属管进行组合、冷拉后在高温下经过较长时间 扩散的方法。这种复合工艺可以在常规的管材生产线上进行。新工艺可以节省贵金属60％以上。采用化学处理的 方法基本上解决了返回料的回收问题。

This paper introduces a new method to produce a duplex matal tube, which is a precious metal tube composed with a common metal tube after cold drawing and diffused at high temperature for a certain period of time. The composite processing can be carried out on the conventional tube production line. The new method can save more than 60% noble metal, and it has solved the problem of the retrieval rejects by chemical treatment basically.
