The mechanism of impurity-induced discharges in plasma electrolysis (PE) was elucidated on the basis of a novel microstructural interpretation. We identified the presence of impurity compounds decorating the rim of the micro-pores, which were ‘fingerprint’ of plasma discharge activities. The formation mechanism of inorganic layer by PE was suggested based on the distribution of impurities and a transient diffusion pattern accompanying plasma discharges.

等离子体电解中杂质引起的放电

在新颖的微观结构解释的基础上阐明了等离子体电解（PE）中杂质引起的放电的机理。我们确定了装饰微孔边缘的杂质化合物的存在，这些杂质是等离子体放电活动的“指纹”。根据杂质的分布和伴随等离子体放电的瞬态扩散模式，提出了PE形成无机层的机理。
