摘要

描述了一种程序，该程序允许通过基于电气测试结果的几个级别的组件评估和选择的系统进展来开发接触材料组合。测试和选择方法旨在开发最佳的接触材料成分，同时也评估成分的变化如何改变被评估材料族的接触性能。具体地说，描述了开发无镉接触材料的程序。与良好的高密度P/M银镉氧化物材料相比，所开发的无镉材料具有优越的耐焊性和更低的腐蚀失重。

The development of silver-based cadmium-free contact materials

A procedure is described that allows contact material compositions to be developed by a systematic progression through several levels of component evaluations and selections based on electrical test results. The testing and selection methodology is designed to develop the best contact material composition while also evaluating how changes in composition can be expected to alter the contact performance of the family of materials being evaluated. Specifically, the procedure is described for the development of cadmium-free contact materials. The cadmium-free material developed is shown to exhibit superior weld resistance and lower erosion weight loss relative to a good high-density P/M silver-cadmium oxide material.<>
