Method of producing a lead dioxide coated cathode |
摘要 |
A long-lived electrode is produced, for use in the electrowinning of metals, by electrodepositing a coating onto the electrode substrate. The coating has a uniform grain size and structure which is controlled by superimposing alternating current onto direct current during electrodeposition.
