title = "Oxidation behavior of glass/yttrium silicates/SiC multi-layer coating coated carbon/carbon composites in air and combustion gas environment at high temperature",
abstract = "Glass/yttrium silicates/SiC multi-layer coating for carbon/carbon (C/C) composite was prepared and the flexural strength and weight changes of the coated samples after oxidation in air and combustion atmosphere at 1500°C were investigated. Results show that when oxidation in air and combustion atmosphere, the C/C composites lost weight by a linear and a parabolic law respectively. The weight loss reaches its maximum value at about 800°C in air but the strength of the specimen arrives at the lowest value at about 850°C. There are three oxidation zones along the specimens. A non-oxidation zone is below 400°C. Close to it is the cracking-oxidation zone (400-1100°C). At the temperature range from 1100°C to 1500°C is the coating-oxidation zone. Fracture of the coated sample at the temperature spot of 850°C is observed after oxidation in combustion atmosphere at 1500°C for 70 hours, which are considered to be responsible for the cracking and decreasing in strength during the test in combustion atmosphere.",
