Preparation and Interfacial Stability of SiCf/Ti-6Al-4V Composites Fabricated Using Powder Coated Fiber Method

Abstract

Abstract: SiCf/Ti-6Al-4V composites were fabricated by the powder-coated fiber method. The precursor fiber was prepared under the optimized parameter, and the composites were made using the vacuum hot pressure method. The influence of heat exposure time on products of the interfacial reaction was investigated using scanning electron microscope (SEM) and analytical transmission electron microscope (TEM) with energy dispersive spectrometer (EDS). The main products are TiC and Ti5Si3 after vacuum exposing the samples at 700℃ for 50 h. The growth dynamics of interfacial reaction products was analyzed quantitatively, which fitted the parabola rule. The activity energy of the reaction was 252 kJ•mol-1.

Key words: Powder coated fiber, SiCf/Ti-6Al-4V composites, Interfacial reaction, Kinetic, Activity energy
