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.
