过去,我厂根据外国资料生产的PdAg_(23)和PdAg_(25)Au_5两种牌号的钯合金,在广泛使用过程中发现一些不足之处,如机械性能较差等。我们知道,我国钯资源缺少。提高钯合金的透气率提高使用寿命的任务就自然而严肃的摆在我们面前。
In the past, based on foreign materials, our factory produced two kinds of palladium alloys, PdAg_ (23) and PdAg_ (25) Au_5, which found some shortcomings during the extensive use, such as poor mechanical properties. We know that there is a shortage of palladium resources in our country. Improve the permeability of palladium alloy to improve the life of the task on the natural and serious before us.
