采用XPS、SEM等技术对耗散防热材料静态氧化试验中氧化膜的生成情况及氧化微观形貌进行了研究,并提出了不同温度及不同氧化时间下Al-Mg/C耗散防热材料静态氧化的吸附模型和扩散模型。氧化模型的建立,为研究该材料的耐烧蚀性能,设计冷却剂的成分提供了相应的理论依据。
The formation and oxidation microstructure of oxide film in the static oxidation test of dissipative heat-resistant materials were studied by XPS and SEM. The effects of Al-Mg / C heat-dissipating materials with different temperatures and oxidation times Static oxidation adsorption model and diffusion model. The establishment of the oxidation model provides a theoretical basis for studying the ablation resistance of the material and designing the composition of the coolant.
