Abstract
Disclosed is a process of surface hardening of Ti-6A1-4V alloy that can be performed by electrolytic charging in an acid solution, subsequent solution treatment, followed by dehydrogenation to obtain an equiaxed alpha grain in transformed beta matrix. Surface hardnesses of the processed specimens are better than that of the mill-annealed specimen. The depth of hardened layer depends on the charging time.
