摘要 介绍了一种适用于化学镀镍工艺的渗氢测量方法 ,可用于监控渗氢速度 ,测定氢在金属中的扩散 ,研究氢脆 ,评估腐蚀阻化剂和酸洗中钢铁的吸氢等方面。化学镀应用中经常要使用加速剂 ,本研究的目标物质是化学镀镍的加速剂———硫脲及其衍生物。在这些物质存在下 ,化学镀镍过程中的渗氢行为不同。良好的加速剂可减少氢渗 ,加快金属的覆盖。 Hydrogen permeation measurements were carried out in electroless nickel plating bath. This technique can be used to monitor permeation rates, determine the diffusivity of hydrogen into metals, study hydrogen embrittlement and evaluate inhibitors, etc. The use of accelerators is meant for high-speed electroless plating prone to many engineering applications. Present investigation examined different thiourea and its derivatives used as accelerators in the EN bath. Their order of performance was justified.
