The Ni substrate significantly reacts with the deposition vapor resulting in porous coatings with considerable amounts of Ni. In contrast, coatings on SiC and aluminoborosilicate fibers are highly crystalline, faceted, dense and show no interactions with the substrate material. -(BORST, M. A.; LEE, W.
