Summary
A process for coating silicon carbide fibers with alumina particulates for control of interface characteristics in the sintering of fiber-reinforced composites is described. The process is based on colloidal slurry processing techniques, in which the fibers are allowed to take up a positive surface charge, while the alumina particles are imparted a negative surface charge. When the oppositely charged fibers and particles are brought together, the particles deposit on the surface of the fibers. Some unique features of the process, as well as characteristics of the resultant coating are described. Process variables of the coating technique that control the coating morphology, thickness, and adherence to the fiber are examined.
