Abstract

The regularities of the effect of the duration of coatings' galvanostatic formation in Zr(SO₄)₂ electrolyte on their composition, structure, surface contact angle with water, and the time of emergence of electrostimulated pitting when samples are in contact with an aqueous NaCl solution have been studied. It has been shown that coatings formed on titanium in the range of transition from the sparkling stage to that of more powerful microarc electric discharges are relevant for anticorrosive properties. The interrelation between the anticorrosive properties of PEO coatings and the stages of their growth may be of general character in PEO treatment of valve metals and alloys of different nature in electrolytes with varying compositions.

含氯介质中等离子体电解氧化形成钛上ZrO 2 + TiO 2涂层的稳定性

摘要

Zr（SO ₄）₂电解质中涂层的恒电流形成持续时间对其组成，结构，与水的表面接触角以及当样品与NaCl水溶液接触时电刺激蚀斑出现时间的影响规律。解决方案已被研究。已经表明，在钛上形成的涂层在从起泡阶段到更强的微弧放电的过渡范围内与防腐性能有关。PEO涂层的防腐性能与其生长阶段之间的相互关系可能在具有不同成分的电解质中对阀门金属和不同性质的合金的PEO处理中具有普遍特征。
