首次从水溶液中通过电生酸法在阳极上沉积了附着力的BaSO4涂层。在低电流密度下，可获得由无取向微晶组成的厚的、几乎连续的涂层。在较高的电流密度下，涂层不是连续的，但结晶是定向的。在短沉积时间和高电流密度下，微晶沿a轴垂直于衬底取向。在长时间沉积时，取向转换为c轴。在类似条件下进行化学沉积可得到既无取向也无刻面的微晶。
Adherent BaSO4 coatings have been electrochemically deposited on anode substrates from aqueous solution for the first time by electrogeneration of acid. At low current densities, thick, nearly continuous coatings comprising unoriented crystallites are obtained. At higher current densities, the coatings are not as continuous but the crystallites are oriented. At short deposition times and under high current densities, the crystallites are oriented with the a axis perpendicular to the substrate. At long deposition times, the orientation switches to the c axis. Electroless deposition under similar conditions yields crystallites that are neither oriented nor facetted.
