Methods of protecting metal surface during exposure to fluoride ion-containing acidic fluids |
| abstract |
A method of reducing corrosion of a metal surface comprises contacting a fluoride ion-containing acidic fluid with a corrosion inhibitor composition before the fluoride ion-containing acidic fluid contacts the metal surface, the corrosion inhibitor composition comprising a zirconium compound, an antimony compound, or a combination comprising at least one of the foregoing; and exposing the metal surface to the fluoride ion-containing acidic fluid. |
