Study Affection of Nano-Al₂O₃ Additive on the Corrosion Resistance of Micro-Arc Oxidation Film of Titanium Alloy TC4

Abstract:

Study the affect of nano-Al2O3 additive on the MAO film of titanium ally, the affect of nano-Al2O3 additive on the surface morphology and the thickness is not remarkable, but the nano-Al2O3 additive is good to improve corrosion resistant of the film. The mechanism of nano-Al2O3 additive improving corrosion resistant of the film is that: on the one hand is improving the content of α- Al2O3 in the film, on the other hand is decreasing the size of the pore area of the film and improving the dense of the loose and compact layer.
