I would like to conduct electroplating at -1.8V in a pH=2 solution that contained FeCl3, InCl3, thioacetamide, and phosphate acid.
Before the electrolysis, I ultrasonicated Ni foams in 6M HCl, ethanol, and deionized water, each for 15min as pre-treatment.
However, no sooner had the electrolysis began in the solution above than the pre-treated Ni foams simply dissolved.
