An investigation of the failure mechanisms of aluminum cathodes in zinc electrowinning cells
Aluminum cathodes have long been used for the electrowinning of zinc from zinc sulfatesulfuric acid electrolyte. Severe corrosion above the electrolyte/air interface limits the life of aluminum cathodes to ca. 18-24 months for a 6 mm thick plate. The failure characteristics of aluminum cathodes w...
