The City University of Hong Kong recently announced that its research team has successfully developed the world's first super-nano-magnesium alloy material, which is 10 times stronger than existing super-strong magnesium alloy crystal materials and has a deformation capacity twice that of magnesium-based metallic glass. Can be developed into biodegradable implant materials. According to reports, after more than five years of efforts, the research team developed an alloy film structure with a two-phase structural unit of less than 10 nanometers and named it "super nano-phase - glass nanocrystal". This is the world's first series of alloy structures with ultra-high strength, can withstand more than 300 kg per square millimeter, and has high wear resistance and deformability.
Lv Jian, vice president of the City University of Hong Kong and professor of mechanical engineering, who led the research project, said: "This material has great application potential and can be used for biodegradable implants. It has ultra-high wear resistance and patients can avoid it. The second surgery to remove the parts. At the same time, magnesium is a beneficial element for the body and helps to recover."
According to reports, this new material can be made into a coating on the artificial joints of the human knee and hip, improve the joint's anti-wear and anti-corrosion ability, and reduce the risk of the patient's sensitivity to the artificial joint metal. It can also be applied to MEMS to extend system life.
Lu Jian said that magnesium alloy has a low density and is an ideal lightweight structural material. It has broad application prospects in the consumer electronics industry, aviation and automotive fields.
