Abstract Scope |
Titanium implants have osseointegration limitations in orthopedic applications, so a coating process is necessary to improve their biological response. Titanium carbide (TiC) has been investigated as a biomaterial in the form of a thin film used in metallic scaffolds as a site for adhesion and cell proliferation, also for improving the osseointegration. However, it is possible the fabrication of three-dimensional porous TiC structures with mechanical properties suitable for applications in bone restoration. This investigation is focused on the fabrication of TiC foams by powder technology from mixtures of commercial titanium hydride powders, phenolic resin, and a foaming agent as precursors materials in various proportions. Microstructure, composition, and phases of TiC foams were characterized by scanning electron microscope (SEM) and X-ray diffraction. An overall porosity of the sintered samples ranges from 81 to 91 % with a pore size of 15-800 μm. The compressive strength and elastic modulus are also reported. |
