In-situ preparation of TiB₂-TiB-Ti functionally graded materials by improved sintering process

Abstract

An improved multi-step sintering process was used to in-situ prepare TiB₂-TiB-Ti FGMs. According to the sintering temperatures, the functionally graded materials (FGMs) were divided into three sections. After sintering at a proper temperature, the three sections were sintered together in turn. The experimental results showed that there were no obvious pores and cracks in the whole TiB₂-TiB-Ti FGMs, and no delamination was found in the impacting test with good performance features, which indicated that there were no interface effects in FGMs during penetration, so that the TiB₂-TiB-Ti FGMs were an ideal FGM.
