本文论述了锆铝合金消气剂吸气性能测试的方法和装置,以及测试中的主要影响因素。利用恒定消气剂表面压强(Pg)的动态定压法,对我院研制、生产的锆铝合金消气剂对N_2、CO和H_2的吸气能力,以及激活特性作了初步研究。并同SAES公司的同类型产品作了比较测定。
This paper discusses the method and device for testing the gettering performance of zirconium-aluminum getters, as well as the main influencing factors in testing. The dynamic pressure-fixing method of constant getter surface pressure (Pg) was used to study the aspirating capacity of N_2, CO and H_2 and the activation characteristics of the zirconium-aluminum alloy getters developed and produced in our hospital. And SAES with the same type of product made a comparative test.
