This project focuses on developing and evaluating a novel orthopedic implantprototype, which combines magnesium-calcium and nitinol through a micro laser welding process. The primary objective is to create a biocompatible, biodegradable scaffold for orthopedic applications, offering an alternative to traditional implants. A series of welding experiments were conducted using a PRECO laser welding machine, where different welding parameters, including laser power and exposure time, were tested to optimize the microhardness and mechanical properties of the welds. The simulation and experimental results were compared to validate the design choices and ensure the scaffold's structural integrity. The microhardness tests indicated that the best results were achieved with 200 watts of power and 18 ms exposure time, creating a prototype scaffold for further testing. Future work includes optimizing scaffold designs and conducting compression and degradation tests to evaluate the implant's mechanical performance and corrosion resistance in physiological conditions. This project aims to contribute to developing advanced, sustainable orthopedic implants with improved performance and biocompatibility.
