摘要
Abstract
SiC ceramic was joined using 22Ti-78Si (wt%) brazing alloy which was prepared by the non-consumable arc-melting technology. The effects of brazing parameters on the microstructures and the fracture morphologies of the brazed joints were investigated by SEM. The mechanical properties of the brazed joints were measured by a universal mechanical testing machine. The results show that SiC ceramic is successfully joined in a proper condition, brazing temperature of 1380-1420°C, soaking time of 5-20min and the brazing alloy thickness of 50-200μm. The maximum shear strength of the brazed joint reaches 125 Mpa at brazing temperature of 1400°C, soaking time of 10min and the brazing alloy thickness of 100μm.关键词
