文摘
- •
Anodization of aluminum in mixed sulfuric-chromic acid electrolytes was performed.
- •
Increase of chromic acid molar fraction decreases the current density and oxide growth rate.
- •
Interpore distance increases with the molar fraction of chromic acid.
- •
Pores density decreases with the increase of the molar fraction of chromic acid.
- •
Logarithm of current density and oxide growth rate was a quadratic function of voltage.
