Preparation and Performance of Micro-Arc Oxidation Ceramic Coating of Titanium Alloy in Low Current Density
In this paper, Three types of electrolyte (phosphate, silicate, aluminum) are considered to make preparation for micro-arc oxidation coatings on titanium alloy by bipolar pulse MAO oxidation power with low power consumption (density of current less than 1A/dm2). Treated by micro-arc oxidation, dense micro-arc oxidation ceramic coating is formed on titanium alloy. Surface morphology and friction coefficient of MAO coating is analyzed. The research on the effect of NaF on ablation of MAO coating is prepared, which guides the configuration of the electrolyte later.
