The results of studies on the preparation of titanium carbosilicide with porosities of 20, 40, and 60% are presented. Experimental samples were obtained using a pore former in the form of NaCl crystals. Sintering of porous samples at temperatures up to 1300°C was characterized using thermomechanical analysis. The pore structure was studied at the macro- and micro-levels using the method of optical microscopy. The nature of the oxidation of the studied samples was revealed based on mass change with the duration of tests and intensity of corrosion in air at 1100°C. X-ray diffraction analysis and Raman spectroscopy results showed that during high-temperature oxidation, predominantly titanium oxide is formed in the form of rutile.

多孔碳硅化钛的制备及耐热性

给出了制备孔隙率为20%,40%和60%的碳硅化钛的研究结果。使用NaCl晶体形式的成孔剂获得实验样品。使用热力学分析表征了多孔样品在高达1300°C的温度下的烧结。使用光学显微镜方法在宏观和微观两个层面研究了孔结构。根据质量随测试时间的变化以及在1100°C下空气中的腐蚀强度,揭示了研究样品的氧化性质。X射线衍射分析和拉曼光谱结果表明,在高温氧化过程中,主要以金红石形式形成氧化钛。
