Research Progress on Corrosion Resistance of Micro-arc Oxidation Coatings on Titanium Alloys
Titanium alloy has excellent comprehensive properties and is widely used in aerospace,automotive,medical and other fields.But its wear resistance is poor,corrosion resistance can not meet the needs of some special environments.Micro-arc Oxidation(MAO)technology can be used to prepare a composite ceramic coating on the titanium alloy surface to improve its performance.In this paper,the research status of the influence of electrolyte type on the corrosion resistance of titanium alloy MAO coating is reviewed.
