In order to improve the oxidation resistance of C_f/Cs produced by chemical vapour infiltration, a multilayer coating based on silicon carbide and molybdenum disilicide was produced by two-step pack cementation technique. The inner SiC layer with a thickness up to 25 μm was obtained without promoted reaction additives by varying the composition, and thermal treatment conditions. The SiC/SiC-MoSi₂ coating was produced with a thickness up to 80 μm by two step pack cementation, considering the effect of the inner layer characteristic. The enhancement of the oxidation resistance, observed in SiC/SiC-MoSi₂ coated C_f/Cs by means of thermal analysis in flowing air up to 1500 °C, was due to the formation of SiO₂ promoted by the passive oxidation of silicon carbide and molybdenum disilicide.

为了提高化学气相渗透法产生的C _f / Cs的抗氧化性，通过两步填充胶结技术制备了基于碳化硅和二硅化钼的多层涂层。通过改变组成和热处理条件，可以获得厚度不超过25μm的内部SiC层，而没有促进反应的添加剂。考虑到内层特性的影响，通过两步填充胶结生产了厚度最大为80μm的SiC / SiC-MoSi ₂涂层。在高达1500°C的流动空气中，通过热分析在SiC / SiC-MoSi ₂涂层的C _f / Cs中观察到的抗氧化性增强是由于SiO ₂的形成 由碳化硅和二硅化钼的被动氧化促进。
