摘要
纯铝不宜作为牺牲阳极材料,必须合金化。合金元素的加入,可使铝的钝化膜受到破坏而正常溶解,同时使阳极晶粒细化、电位变负。熔炼了五种不同的Al-Zn-In系合金牺牲阳极材料,采用恒电流法,测定了不同温度下的阳极电化学性能。结果表明:牺牲阳极的电化学性能随着温度的升高而降低;牺牲阳极的表面溶解状态随温度升高变得不均匀;研究了牺牲阳极的综合电化学性能和表面溶解状态,结果表明,研制的2号阳极是高温下较好的牺牲阳极材料。
The Authors studies five distinct Al-Zn-In family alloy anodic sacrifice materials,using constant current method determines the anodic electrochemic properties under different temperatures. Results show that Along with the temperature increases the electrochemic properties of anodic sacrifice decreases and along with the temperaure increases the surface dissolving status turn uneven. They show that the developing No2 Anode is a better anodic sacrifice material under high temperature.
