Abstract To enhance the oxidation resistance of carbon/carbon composites, here we designed and fabricated a novel β-Y 2 Si 2 O 7 nanowire-toughened Y 2 SiO 5 /Y 2 O 3 -Al 2 O 3 -SiO 2 coating by pulse arc discharge deposition with a later hot dipping process onto SiC coated carbon/carbon composites. Triple protection of the nanowire toughening, inlaid phases and compound Y 2 O 3 -Al 2 O 3 -SiO 2 glass ceramic layer are contributed to the good oxidation resistance of this coating. After 50 thermal cycles between 1673 K and room temperature, the weight loss of coated samples was only 36.0 g·m −2 , and the weight loss of the coated samples was only 31.7 g·m −2 in air at 1673 K for 176 h.

用于碳化硅包覆碳/碳复合材料的抗氧化β-Y 2 Si 2 O 7 纳米线增韧Y 2 SiO 5 /Y 2 O 3 -Al 2 O 3 -SiO 2 玻璃陶瓷涂层的新设计

摘要 为了提高碳/碳复合材料的抗氧化性，我们设计并制备了一种新型的β-Y 2 Si 2 O 7 纳米线增韧Y 2 SiO 5 /Y 2 O 3 -Al 2 O 3 -SiO 2 涂层。电弧放电沉积与后来的热浸工艺到 SiC 涂层的碳/碳复合材料上。纳米线增韧、镶嵌相和复合Y 2 O 3 -Al 2 O 3 -SiO 2 玻璃陶瓷层的三重保护有助于该涂层具有良好的抗氧化性。在1673 K和室温之间进行50次热循环后，涂层样品的重量损失仅为36.0 g·m -2 ，涂层样品在1673 K空气中176小时的重量损失仅为31.7 g·m -2 .
