SPS烧结诱发自蔓延反应制备Ti3SiC2-金刚石复合材料
Fabricating Ti3SiC2-diamond composites by spark plasma sintering induced self-propagation reaction
摘要
Abstract
Ti3SiC2-diamond composites were fabricated by spark plasma sintering induced selfpropagation reaction with 3Ti/Si/2C powders as bonder.The effect of holding time on the phase composition and microstructure of composites were studied.The result shows that Ti3 SiC2 phase is formed when heated at 1170 ℃,whose main phases are Ti3SiC2,Ti5Si3 and TiC.It is also found that Ti3SiC2 content in the sample obtained at 1500 ℃ is higher with fully reacted raw materials.The main phase of the sample containing 10wt%0 diamond is TiaSiC2 and TiC.Additionally,small amounts of Si,SiC and diamond are also obtained.Ti3 SiC2 content in the sample with holding time of 1 min is higher,whose grains is lathe-structured and bonds well with diamond.Ti3SiC2 content in the sample with holding time of 5 min is lower,mainly composed of many TiC particles.In addition,the diamond is seriously graphitized,forming thick transition layer.关键词
