Effect of electrolyte concentration on anodised titanium in mixture of B-Glycerophosphate (B-Gp) and Calcium Acetate (Ca)
Anodic oxidation is a surface modification method which combines electric field driven metal and oxygen ion diffusion for formation of oxide layer on the anode surface.

| Summary: | Anodic oxidation is a surface modification method which combines electric field driven metal and oxygen ion diffusion for formation of oxide layer on the anode surface. This study aimed to investigate the effect of electrolyte concentration on titanium. Specifically, the titanium foil was anodised in mixture of P-glycerophosphate disodium salt pentahydrate (P-GP) and calcium acetate monohydrate (CA) with different concentration (0.02 M + 0.2 M and 0.04 M +
0.4 M), anodising time (1, 3, 5 and lO.,min), applied voltage (150, 200, 250, 300 and 350 V) and current density (10 and 20 m~.cm-~)
at room temperature. Surface oxide
properties of anodised titanium were
characterised by using glancing angle X-ray
difiaction (GAXRD), field emission
scanning electron microscope (FESEM),
focused ion beam (FIB) milling and digital
camera. This study indicated the porosity and
crystallinity of the oxide layer depended
strongly on the electrolyte concentration |
