Abstract

The manuscript presented the application of in-situ TAG (high-temperature oxidation analyzer) and TG-MS-FTIR (Thermogravimetry, Mass spectrometer and Fourier transform infrared spectrometer) techniques for further characterization of TiBw oxidation products in TA15 matrix composite. The volatile ingredient and chemical bonding measurement results revealed the existence of B2O3 and H3BO3, which generated during the oxidation process of TiBw/TA15 composite. Compared with TiCp/TA15 composite, the cyclic oxidation kinetic and microstructure observation results indicated that TiBw/TA15 composite had superior oxidation resistance, which resulting from well-designed network structure.
