Abstract

The electrocrystallization of deposited on a Ti plate from a nitrate solution is strongly affected by the presence of additives in the solution, examples being sodium dodecylsulfonate, Triton‐X100, Tween‐80, dextrin, and gelatin. Results of SEM investigations show that these additives tend to diminish the crystalline morphology of the deposit. The XRD results further indicate that it is possible to codeposit by introducing the surfactant‐type additives sodium dodecylsulfonate, Triton‐X100, and Tween‐80. Stirring provided during electrodeposition tends to diminish the influence of sodium dodecysulfonate, but not that of Triton‐X100 and Tween 80. The nonsurfactant‐type additives, dextrin and gelatin, do not cause the codeposition of to any significant degree.
