Methods and systems utilizing a boron-containing corrosion inhibitor for protection of titanium surfaces

Abstract

Some sensitive metal surfaces are often unable to be contacted effectively with hydrofluoric acid or acidic fluoride ions due to significant corrosion issues that may occur. Metal surfaces comprising titanium or a titanium alloy represent but one example of sensitive metal surfaces having this issue. Corrosion inhibitor compositions comprising boric acid and other boron-containing compounds may at least partially suppress corrosion of titanium and titanium alloy surfaces. Methods for suppressing corrosion may comprise: contacting a metal surface comprising titanium or a titanium alloy with a corrosion inhibitor composition comprising a boron-containing compound; and interacting the metal surface with a fluid phase comprising hydrofluoric acid or acidic fluoride ions.
