- Abstract
Friction stir processing (FSP) has been used to fabricate surface metal matrix composites utilizing the newly commercialized ZE41-rare earth magnesium alloy (in cast form) using nano-Al 2 O 3 , nano-CeO 2 and nano-Multi-walled carbon nanotubes as reinforcement particles. The results of microstructural examination revealed the refinement of grains from 113 μ m to 1.41 μ m. The microhardness was observed to increase significantly, the range of increase being from 71 HV to 134 HV. The tensile strength of the surface composite was found to vary from 154 MPa to 201.5 MPa. All the fabricated composites show better wear resistance as compared to the base material. The wear performance of the ZE41-CeO 2 composite was seen to be the highest compared to other fabricated composites because of the solid lubrication effect provided by the CeO 2 particles. Delamination and abrasive wear were identified as the predominant wear mechanisms in all the fabricated composites due to presence of hard reinforcement particles.
