Precision Manufacturing of Advanced Ceramic Materials

Ceramics are good materials for bearing surfaces, including orthopedic implants, because of their high hardness and electrochemical inertness. These properties also make them extremely difficult to machine. We are studying advanced precision manufacturing methods such as laser machining and electric discharge machining (EDM) for these ceramic materials. We quantify the material removal, accuracy, and effect on microstructures and material properties to optimize the manufacturing processes.
