本文概述辽宁电偶会战组开展高温代铂电偶材料的研制情况。重点是以含钇的镍铬_(10)—镍硅_(2.5)新型电偶为主要研究对象,并详细地考核加入微量元素钇(0.05—0.15％)对电势稳定性和抗氧化性能的影响。对高温抗氧化机理只作初步的讨论。通过对所研制的新型电偶在工业生产中使用性能的试验,认为该电偶材料可以代替铂铑—铂电偶在1300℃温度以下应用。
This article summarizes the development of the generation of high-temperature platinum electrocatalytic materials in the Liaoning Electro-Aeon Combat Team. The emphasis is on the new yttrium-containing nickel-chromium _ (10) - nickel-silicon _ (2.5) new galvanic couple as the main research object, and a detailed examination of the addition of trace elements yttrium (0.05-0.15%) on the potential stability and antioxidant properties influences. Only a preliminary discussion of the mechanism of high temperature oxidation resistance. Through the test of the performance of the new type of galvanic couple in industrial production, it can be considered that the galvanic couple can be used instead of the platinum rhodium - platinum galvanic couple below 1300 ℃.
