摘要
为了了解WC-Co合金废料在盐酸溶液中使钴选择性溶解的阳极行为,采用了动电位扫描法研究不同的工艺条件对阳极溶解的影响,测定了阳极中钴溶解的控制步骤,并对阳极钝化的原因作了初步探讨。
In order to learn the selective dissolving behaviors of Co contained in WC-Co scraps in hydrochloric acid solution,a dynamic potentiometric scanning method is adopted to study the effect of different working conditions on the selective dissolving behaviors.The procedures for controlling the dissolving rate of Co contained in the anode are determined and the cause of anode passivation is investigated.
