EFFECT OF RUST ON THE WETTABILITY OF STEEL BY WATER
Rust, as formed on steel by immersion of low-carbon steel in water, was found to improve the wettability of steel by water. The advancing contact angle decreased from 87° to 32°, and the receding contact angle decreased from 81° to 29°. Cleansing of steel by acetone also helped improve the wettability, but the advancing angle only decreased from 87° to 73°, and the receding angle only decreased from 81° to 41°.
