摘要

用光学显微镜、电子显微镜和x射线衍射研究了β′有序黄铜在去氧2.0 M H2SO4中溶解的固体产物。结果表明:锌浸出层厚度随时间的变化满足Erofeev方程,相间区存在一层锌含量变化的层,β′有序黄铜表面出现一层贝氏体结构的黄铜。在假设氢离子还原是电化学过程的速率决定步骤的基础上,证实了黄铜溶解速率控制金属铜相形成和生长的假设。

Kinetics of the spontaneous dissolution of copper-47.3 atom-% zinc brass with hydrogen depolarization

The solid products of the dissolution of β'-ordered brass in deaerated 2.0 M H2SO4 have been studied by optical and electron microscopy and X-ray diffraction. It has been found that the thickness of the zinc-leached layer as time function satisfies the Erofeev equation, a layer of variable zinc contents exists in the interphase zone: brass-pure copper and a brass of bainite structure appears at the surface of the β'-ordered brass. On the assumption that the reduction of H+ ions is the rate-determining step of the electrochemical process the hypothesis that the rate of dissolution of brass controls the formation and growth of metallic copper phase has been corroborated.
