| Abstract: |
| Micro-arc oxidation (MAO) technology is often used in the surface treatment of medical titanium alloys, giving them abrasion-resistant, corrosion-resistant, or osteogenic properties. The performance of the MAO coating is determined by a combination of factors, such as power supply mode, voltage/current size, electrolyte type, oxidation time, additives, etc. The composition of the electrolyte is one of the key factors affecting the structure and performance of the MAO coating. Sodium tetraborate is used as a single electrolyte for micro-arc oxidation, and due to its special discharge method, the coating often results in high corrosion resistance. However, when sodium tetraborate is used as an additive, it not only plays a discharge role, but also may react with the coating, and the effect of adding sodium tetraborate to different electrolytes is worth exploring. The work aims to improve the wear resistance and corrosion resistance of micro-arc oxidation coatings on titanium alloy and develop better composite electrolytes. |
