Hybrid Ti_2AlC Bonded Diamond Composites Prepared by a Self-propagation Sintering Approach
|
摘要
Ti, Al, graphite and diamond powders were used as raw materials to prepare Ti_2AlC matrixbonded diamond composite using self-propagating high-temperature synthesis(SHS) method. The effect of diamond size and content on the fabrication of Ti_2AlC-bonded diamond material was investigated. Results showed that Ti_2AlC matrix-bonded diamond composites could be obtained by SHS. The phase composition and microstructure of the Ti_2AlC-bonded diamond material were influenced by the diamond content and size. When the diamond(93 μm) additive amounts were 10% and 20%, the product phases included Ti_2AlC, TiC and Al_3Ti. However, excess Ti and Al persisted in the sample that contained 30% diamond. Diamond bonded well with the matrix in the sample that contained 10% diamond. Moreover, addition of coarse diamond particles with sizes of 93 and 125 μm produced a mainly Ti_2AlC matrix. However, diamond adequately reacted with Ti to form TiC when finer diamond particles(5 and 10 μm) were used.
