Abstract:
1. A method of fabricating a porous metal-based biomaterial for dental and orthopedic implants, the method comprising: dispersing carbon-based microwave susceptors into a first organic solvent to form a homogeneous suspension, the carbon-based microwave susceptors are in micrometer or nanometer scale; dispersing bioactive fillers into a second organic solvent to form a homogeneous solution; mixing titanium or titanium alloy powder with the homogeneous solution and the homogeneous suspension to form a metal-based mixture; cold-pressing the metal-based mixture into a metal-based compact; and placing the metal-based compact in a sintering container and emitting microwave to sinter the metal-based compact, and remove the first and/or second organic solvent resided in the metal-based compact at the same time, wherein the carbon-based microwave susceptors are burned off by heat generated during the microwave sintering to form porosity.
