  • BIODEGRADABLE IMPLANTS WITH ANTICORROSIVE COATINGS
    Publication number: 20240075184
    Abstract: Provided are biodegradable orthopedic implants, corrosion-resistant coating for orthopedic implants, and methods of making. The biodegradable orthopedic implant can include a Mg alloy having a coating including a first layer, a second layer, and a third layer. The first layer can be an oxide layer coated on an external surface of a magnesium alloy implant. The second layer can include lawsone embedded in PCL, and the third layer can include PCL. To manufacture the coated orthopedic implant, the implant can be immersed in an alkaline solution to form an oxide-coated implant and implant can then be coated with a PCL lawsone solution. An additional polymer protective layer can be added.
