When either uncoated or BN-coated Nicalon fibers are exposed to water saturated with NaCl before being annealed in air at 1,000 C, accelerated degradation of the structure of the fiber occurs. The fiber surface oxidizes to tridymite instead of vitreous silica, and the crystallites of SiC in Nicalon begin to grow. These findings suggest that prior exposure to salt water may cause appreciable debit in the mechanical strength of nicalon fibers with time at 1,000 C in air.
