The influence of the glycerin concentration on the porous structure of ferritic stainless steel obtained by anodization

Anodizing of ferritic stainless steel has been used for decoration purposes to obtain a barrier effect. The most commonly used electrolyte for this process is INCO (5M H2SO4 + 2,5M CrO3). INCO electrolyte with glycerin addition induces the formation of ordered porous structures, because glycerin red...
