Abstract

Si₃N₄ is a ceramic material attracting attention in many fields because of its excellent abrasion resistance. In addition, Ti and TiAl alloys are metals used in a variety of high temperature environments, and have attracted much attention because of their high strength and high melting points. Therefore, study of the interface reaction between Si₃N₄ / Ti and Si₃N₄ / TiAl can be a useful practice to identify phase selection and diffusion control. In this study, Si₃N₄ / Ti5Si₃ + TiN / TiN / Ti diffusing pairs were formed in the Si₃N₄ / Ti interfacial reaction and Si₃N₄ / TiN(Al) / Ti₃Al / TiAl diffusion pathway was identified in the Si₃N₄ / TiAl interfacial reaction. The diffusion layers of the interface reactions were identified and, to investigate the kinetics of the diffusion layer, the integrated diffusion coefficients were estimated.
