Research Directions:
Research on Medical Biodegradable Metal Materials:
To address the issues of excessively rapid degradation of magnesium-based materials and excessively slow degradation of iron-based materials for biodegradable vascular stents, proposes a composite coating technology combining micro-arc oxidation and organic drug loading for magnesium alloys, as well as an electrodeposition additive manufacturing scheme for Fe-Zn alloy microtubes alloyed with Zn. Studies include finite element structural optimization design of different material vascular stents, laser cutting and electropolishing processing techniques, material modification and processing technologies, and evaluation of in vivo and in vitro biological properties of the materials.
Bioactivity Modification of Medical Metals such as Titanium and Tantalum via Micro-Arc Oxidation:
To address the poor bioactivity of metals such as titanium and tantalum for hard tissue replacement, proposes a surface modification technology combining micro-arc oxidation and active ion incorporation. Studies the effects of surface micro/nano hierarchical structures and active ion release on the osseointegration ability of implants, and evaluates the in vivo and in vitro biological properties of the materials.
Micro-Arc Oxidation Surface Modification of Valve Metals such as Aluminum, Magnesium, and Titanium:
To address the insufficient surface corrosion resistance and wear resistance of materials such as aluminum, magnesium, and titanium for automotive and aerospace industries, employs a bidirectional high-frequency pulse power supply to perform micro-arc oxidation surface modification on the materials, generating ceramic coatings with corrosion resistance, wear resistance, and high insulation properties on the metal surface. Studies the effects of process parameters such as electrical parameters and electrolyte composition on coating thickness, phase composition, corrosion resistance, and friction and wear resistance.
