中文摘要：

酸硫酸盐洗澡的亚锡的减小上的添加剂的效果被调查用周期、线性打扫 voltammetry，电气化学的阻抗光谱学(EIS ) ，和微观结构分析。当添加剂不在时，听涂层是不平的，并且听 electrodepositing 是氢气体进化伴随的一个单个步的减小过程。酒石的酸的增加在亚锡的减小的山峰水流生产细微减小并且在酸的锡洗澡的稳定性上有有点积极的效果。benzylidene 丙酮和 polyoxyethylene octylphenol 醚妨碍亚锡的减小并且极大地压制氢气体进化。甲醛稍微减少亚锡的减小的山峰水流密度并且在酸硫酸盐洗澡用作辅助 brightener。混合添加剂的存在极大地压制亚锡的减小和氢气体进化并且因而生产显著地更光滑、更稠密的听涂层。(112 ) 水晶脸被发现是听存款的主导、比较喜欢的取向。

英文摘要：

The effects of additives on the stannous reduction of an acid sulfate bath were investigated using cyclic and linear sweep voltammetry, electrochemical impedance spectroscopy （EIS）, and microstructure analysis. In the absence of additives, tin coatings are rough, and the tin electrodepositing is a single-step reduction process accompanied by hydrogen gas evolution. The addition of tartaric acid produces a slight reduction in the peak current of stannous reduction and has an appreciably positive effect on the stability of the acidic tin bath. Both benzylidene acetone and polyoxyethylene octylphenol ether hinder the stannous reduction and greatly suppress the hydrogen gas evolution. Formaldehyde slightly decreases the peak current density of stannous reduction and serves as an auxiliary brightener in the acid sulfate bath. The presence of mixed additives greatly suppresses the stannous reduction and hydrogen gas evolution and consequently produces a significantly smoother and denser tin coating. The （112） crystal face is found to be the dominant and preferred orientation of tin deposits.
