- •
5000 mesh silty sand enhanced Cr enrichment in corrosion scale, leading to low corrosion rate and uniform corrosion.
- •
1000 mesh silty sand deteriorated Cr enrichment in corrosion scale, leading to high corrosion rate and localized corrosion.
- •
Anodic current of 3Cr steel reduced for 5000 mesh silty sand and increased for 1000 mesh silty sand.
- •
Cr enrichment in corrosion scale of 3Cr steel was affected by separation effect of silty sand.
