2. Materials and Methods
2.1 Sample Preparation
CPTi, Ti6Al4V, and Ti6Al4V-ELI rods of medical grade
were cut with high-speed saw into circular disks samples
having thickness of 0.5089102 m and diameter of
1.5889102 m. Samples were grinded with standard metallographic
preparation procedures using Buehler abrasive belt
grinder. Tap water was used to clean the debris from samples
during abrasive polishing. Each sample was cleaned with
deionized water prior to polishing and then ultrasonically
cleaned with acetone for 15 min. EP and MEP treatments were
performed by Electrobright (Macungie, PA, USA).
