Effect of SnO₂ Coating on the Low Temperature Extrusion of 6061Al Matrix Composite Reinforced with Aluminum Borate Whisker

Abstract:

The 6061Al matrix composites reinforced with SnO₂-coated aluminum borate whisker were fabricated using squeeze casting method. The composites with different SnO₂ coating contents were extruded successfully at 350°C with the extrusion rate of 18mm/s. The results show that the Sn particles at the interface as liquid state at extrusion temperature result in the reduction of the extrusion load and the decrease of the probability of whisker fracture during hot deformation process. Moreover, unlike many surface cracks can be seen in the extruded composite without whisker coating, the surface crack-free extruded rods can be obtained for composites with whisker coating. The ABOW/SnO/6061Al composites tensile properties increased obviously after extrusion.
