【摘要】 采用周期伏安技术、恒电位阶跃法和可见光光谱技术研究了自然陈化和电化学陈化对Ni/Cr合金自NiCl₂-CrCl₃体系中电沉积的电化学行为和沉积层质量的影响。研究表明,自然陈化和电化学陈化对于保持一定组成和高质量的Ni/Cr合金共沉积是需要的;电化学陈化所产生的少量Cr²⁺离子对Ni/Cr合金的质量和组成是一个重要的控制因素。更多还原

【Abstract】 The effects of natural ageing and electrochemical ageing on the electrochemical behaviour of Ni-Cr alloys plating and quality of the alloys deposits have been investigated. It was shown that natural ageing and adequate electrochemical ageing were important to sustain high quality Ni—Cr alloy deposits of constant composition in the electrodeposition of Ni—Cr alloys from NiCl₂—CrCl₃ electrolytic system; a little electrolytically generated Cr²⁺ could play an active controlling role upon the composition and the quality of Ni—Cr alloy deposits.更多还原
