Influence of Na₂SiO₃ Concentration on the Corrosion Behavior of TC₄ Ceramic Coatings

Abstract:

The micro-arc oxidation technology were utilized to fabricated the ceramics coating in order to improve the corrosion resistance of Ti–6Al–4V alloy (TC₄). The sodium silicate solution was introduced into the electrolyte solution for increasing the coating properties. The effect of the sodium silicate content on the phase composition, surface morphology and potentiodynamic polarization behavior was investigated. The results showed that the increase of Na₂SiO₃ concertration was benefit to improve corrosion resistance of the MAO coating of TC₄ alloy. Key words: Micro-arc oxidation, Ceramic Coatings, Corrosion Resistance.
