According to a study from Xian, People's Republic of China, "In order to protect carbon/carbon (C/C) composites against oxidation, a Si-Mo-W coating was prepared on the surface of SiC-coated C/C composites by a simple reaction method. The microstructures of the as-received coating were characterized by scanning electron microscopy, X-ray diffraction, and energy dispersive spectroscopy analyses."
"The results show that the SiC/Si-Mo-W coating can protect C/C composites from oxidation in air at 1673 K for 220 h with a mass loss of 0.003%, and at 1773 K for 252 h with a mass gain of 1.56%. The excellent oxidation-resistant property of the SiC/Si-Mo-W coating at ...
