摘要

有一些案例研究表明，涂层(热浸镀锌和粉末涂料双相涂层)的缺陷是由氢气充入基体钢。钢暴露在盐酸中，然后在更高的温度下形成锌涂层。在截面上显示了氢复合及其分子从涂层扩散的证据。氢的释放也导致了后续粉末镀锌板的缺陷。

The effect of hydrogen charging on the quality of zinc and powder paint coatings

There are shown some case studies when the defects in coatings (hot dip galvanised and duplex coatings with powder paints) were caused by hydrogen charging into matrix of substrate steel. Steel was exposed into hydrochloric acid and then the zinc coatings had been formed at higher temperature. The evidence of hydrogen recombination and its molecules ́ diffusion from coating layers is shown on cross-sections. The hydrogen release caused the defects on subsequently powder coated galvanized plates, too.
