Abstract

The goal of this project was to explore alternatives to the use of hydrofluoric acid in the removal of alpha case from the surface of forged titanium for the Wyman-Gordon Company. Both fluoroboric acid and a solution of sodium fluoride and ammonium persulfate were experimentally tested. Results showed that hydrofluoric acid had the highest etch rate over 6 minutes. Recommendations for future research were made to improve the current process.
