Stress measurements in electrodeposited lead dioxide

Consumption of Cetyl Trimethyl Ammonium Bromide (CTAB) during Electrodeposition of Lead Dioxide

“…The mean stress remains tensile even with the electrolyte used for 6 h of electrolysis without replenishing CTAB. The compressive aftereffect is seen in all the solutions as observed earlier (1). The lead dioxide deposits obtained were shiny, smooth, adherent, and free from pinholes.…”

“…Experimental In the course of the study on the measurement of internal stress in electrodeposited lead dioxide from lead nitrate -copper nitrate bath, Gnanasekaran et al (1) found that the addition of CTAB not only lowered the stress but also helped in getting a deposit free from pinholes under stationary condition. The beneficial effect of addition of CTAB and other alkyl trimethyl ammonium bromide during electrodeposition of lead dioxide has been studied in detail and found to give a smooth and adherent deposit of lead dioxide on a stationary graphite anode (2,3).…”

Electrodeposited lead dioxide coatings

“…63 The literature on the electrochemical deposition of pure lead dioxide is very extensive. It is clear that the adhesion, surface morphology, ratio of a/b forms and catalytic activity can be influenced by many parameters including 8,24,46,60,74,[83][84][85][86][87][88][89][90][91] the substrate (Pt, Au, graphite, glassy carbon, Ti, Ti with undercoat, Ta).…”

Electrodeposition of Lead and Lead Alloys

“…In order to keep the metals in the solution and the pH constant, the addition of lead oxide, PbO, and copper metal is recommended [92]. Investigation into the formation of stresses in electrolytically deposited lead dioxide layers were reported by Gnanasekaram and co-workers [93]. The existence of internal stresses can lead to cracks in the anodes and thus can have an adverse effect on the stability and the shelf-life of the anodes.…”
