is strengthened. The coating adhesion and rigidity decrease, which affects electrochemical activity of the anode when the content of IrO2 is too high. The electrochemically active surface area is determined not only by the content of IrO2 but also the structure and morphology of the anode coatings. It is probably due to the existence of proper quantities of inert Ta2O5 which results in a typical morphology......
