Monoclinic ZrO 2 was deposited on several metallic and ceramic substrates by reacting ZrCl 4 , CO 2 , and H 2 at temperatures of 800° to 1050°C. Ni substrates reacted significantly in the ZrO 2 coating environment since the coating was porous and contained a considerable amount of Ni. In contrast, the coating deposited on SiC and aluminoborosilicate fibers was highly crystalline, faceted, and dense without any apparent interaction with the substrate materials.
