通过对不同条件下原位复合制备的各种TIN／O′Sialon材料在空气中的氧化行为研究，考查了氧化温度、气孔率和TiW含量对材料抗氧化性能的影响。结果表明：当氧化温度升高到一定值时，通常材料表层会形成致密的“保护膜”，阻碍材料的进一步氧化；材料的气孔率和TIN含量越低，越易形成“保护膜”，反之，越不易形成“保护膜”。当材料的气孔率为30％以上，TiO2添加量为30wt％以上时，即使在更高的氧化温度下也不能形成“保护膜”。
The oxidation behavior of various TIN / O’Sialon materials prepared by in situ composites under different conditions was investigated in air. The effects of oxidation temperature, porosity and TiW content on the oxidation resistance of the materials were investigated. The results show that when the oxidation temperature is increased to a certain value, the surface of the material usually forms a dense “protective film”, which hinders the further oxidation of the material. The lower the porosity and the TIN content of the material, the easier it is to form a “protective film” and vice versa , The more difficult to form a “protective film.” When the material has a porosity of 30% or more and the amount of TiO2 added is 30% by weight or more, a “protective film” can not be formed even at a higher oxidation temperature.
