Ti颗粒表面包覆处理对镁基复合材料界面及力学性能的影响
Effect of Ti Particle Surface Coating Treatment on the Interface and Mechanical Properties of Mg Matrix Composites
摘要
Abstract
In this study,based on AZ91D,Ti particles and Al-Ti particles coated with Al on the surface of Ti particles by the electroexplosive deposition method were used as reinforced particles.Tip/AZ91Dand(Al-Ti)p/AZ91D composites were produced by the stirring casting process,respectively.The uniformity of distribution of reinforced particles was observed by scanning electron microscopy(SEM),and the interface between the reinforced particles and the matrix were further analyzed.Besides,tensile tests were experimented on the composites,that the indexs of mechanical properties such as tensile strength,yield strength,and elongation of the composites were studied on and the fracture of the composites was analyzed.Since Al-Ti particles coated on the surface could significantly increase the thickness of the interfacial layer,and its special cloud-like interfacial layer made the pinning effect more obvious,compared with Tip/AZ91D composites,(Al-Ti)p/AZ91D composites had higher mechanical properties.关键词
