| Research Abstract |
Plasma electrolytic oxidation (PEO) is an attractive process to form ceramics coatings on light metals, including magnesium, aluminum and titanium, in aqueous electrolytes at ambient temperature. The present study discloses the excellent healing properties of discharge channels in alkaline silicate electrolyte. Further, novel two-step PEO process is developed to form wear-resistant and highly adherent ceramics coating on β-Ti alloy with high mechanical strength and cold workability.
