电镀扩散热处理是七十年代发展起来的一种金属表面硬化新技术,已引起国内外有关技术工作者的重视。其中Delsun法,是在铜合金表面镀锡扩散的表面硬化工艺,为铜合金化学热处理开辟了新的途径,特别是在仪器仪表、电子工业中应用具有广阔的前景。本文讨论黄铜镀锡扩散处理工艺、扩散层组织和性能。一、材料和工艺方法基体材料用99.99％铜和99.95％锌,熔炼成含5％、10％、20％、30％、38％锌的黄铜,经热轧退火后供作试验材料。
Plating diffusion heat treatment is developed in the seventies a metal surface hardening of new technologies, has attracted domestic and foreign technical workers attention. The Delsun method, which is a surface hardening process of tin plating diffusion on the surface of copper alloy, opens up a new way for the chemical heat treatment of copper alloys, and has broad prospects especially for application in instrumentation and electronics industries. This article discusses the brass tin plating diffusion process, diffusion layer structure and properties. First, the material and process The matrix material with 99.99% copper and 99.95% zinc smelting 5%, 10%, 20%, 30%, 38% zinc brass, after hot-rolled annealed for the test material.
