Summary

The evaluation of the surface roughness and texture of the three different Al203 fibers was performed by using the Atomic Force Microscope. They are: as-received fibers, refractory metal coated fibers and Y203/refractory metal duplex layer coated fibers. The refractory metal coating and the Y203 coating on the Al203 fibers were found to increase the surface roughness from 13.3 nm to 17.1 nm and 18.8 nm, respectively. The topographic image of the fibers evaluated by the Atomic Force Microscopy was compared to that obtained by the Scanning Electron Microscopy. The tailoring the mechanical properties at metal/ceramic interfaces by the surface modification of Al203 fibers to improve the overall performance of these advanced materials was also proposed.
