Composites are unique materials that can satisfy difficult design targets. Particulate composites can be fabricated with a range of microstructures tailored to fit a variety of engineering design criteria. For example, components can be designed to operate in marine environments or function in the human body by resisting corrosion and wear. In this project, zirconium carbide/zirconium boride ceramic composites with different residual zirconium contents in the matrix were fabricated and characterized. Corrosion test coupons were machined from as-fabricated composite billets. Microstructural and phase characterization of the as-synthesized and post-test composites were accomplished by optical microscopy and scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS) and X-ray diffraction (XRD). The aqueous corrosion susceptibility of these composites in marine environments was evaluated in accordance with the relevant ASTM standards.
