SiCP表面镀Ti改性对SiCP/Al2014复合材料组织及力学性能的影响
|
Abstract:
采用盐浴镀的方法对SiCP进行表面镀Ti处理，并通过搅拌铸造的方法制备了表面镀Ti改性SiCP/Al2014复合材料。研究了镀Ti SiCP的尺寸和体积分数对SiCP/Al2014复合材料微观组织和力学性能的影响规律。结果表明：表面镀Ti处理能有效改善SiCP在Al基体中的分散均匀性；但随着SiCP体积分数提高，相同尺寸的镀Ti SiCP在Al基体分散均匀性逐渐变差，当SiCP体积分数相同时，其在Al基体中的分散均匀性随着SiCP尺寸的增加逐渐变好。SiCP尺寸相同时，SiCP/Al2014复合材料的常温拉伸强度随颗粒体积分数的增加先增大后减小，SiCP尺寸为5 μm和10 μm的SiCP/Al2014复合材料抗拉强度在颗粒的体积分数为4%时达到最高，分别为524 MPa和536 MPa；SiCP/Al2014复合材料的高温（493 K）抗拉强度随着SiCp体积分数增加而增大，SiCP尺寸为5 μm和10 μm的SiCP/Al2014复合材料抗拉强度在颗粒体积分数为6%时达到最高，分别为308 MPa和320 MPa。 The surface of SiCP was Ti-coated via melt salt, and the Ti-coated SiCP/Al2014 composites were fabricated by stir casting method. The effect law of size and volume fraction of Ti-coated SiCP on the microstructure and mechanical properties of SiCP/Al2014 composites were investigated. The results show that the Ti-coated processing could effectively improve the distribution uniformity of Ti-coated SiCP in Al matrix. When the size of Ti-coated SiCP keeps constant, the distribution uniformity of Ti-coated SiCP in Al matrix decreases with increasing volume fraction of SiCP. When volume fraction of SiCP keeps constant, the distribution uniformity of Ti-coated SiCP in Al matrix increases with increasing size of SiCP. When size of SiCP keeps constant, the tensile strength of SiCP/Al2014 composites at room temperature increases first then decreases with increasing volume fraction of particles. The SiCP/Al2014 composites with 4% volume fraction of particles possess the highest tensile strength, i.e., composites containing SiCP with sizes of 5 μm and 10 μm correspond to tensile strength of 524 MPa and 536 MPa, respectively. The tensile strength of SiCP/Al2014 composites at high temperature (493 K) increases with increasing volume fraction of SiCP. SiCP/Al composites with 6% volume fraction of particles possess the highest tensile strength. The composite with 5 μm-SiCP exhibits tensile strength of 308 MPa while that with 10 μm-SiCP exhibits tensile strength of 320 MPa when the volume fraction of particles is 6%. 国家“973”计划（2012CB619602）；吉林大学大学生创新训练计划（2015430469）
