Abstract
A technique has been developed for producing coatings from sols of hydrous zirconium and germanium dioxides or hafnium and germanium dioxides on SiC microfibers. The technique allows one to produce homogeneous, dense nanocoatings of controlled phase composition. SiC fiber surface modification under optimal conditions has been shown to have no significant effect on the mechanical tensile strength of the fibers. Zirconium germanate and hafnium germanate coatings on SiC fibers favor fiber debonding and pullout from the SiC matrix.
