Optimum FSP Parameters Determination to Fabricate Wear resistant AZ31-MWCNTs Surface Composite abstract
In the current study an AZ31/MWCNTs surface composite was fabricated through friction stir processing on a L36 Taguchi design to investigate the importance of the processing parametersand predict the optimum parameters. The response properties were coefficient of friction (COF) and specific wear rate as a representative for resistance to the wear. The COF in all FSPed composite samples decreased up to 0.2 from about 0.6 in as received sample. The FSPed noncompositesamples also showed lower COF than the as received sample (up to about 0.3). Resistance to wear in both FSPed and composite sample were higher than that of the as receivedsamples. The most important parameters influencing the COF and resistance to wear were theCNT amount and the pass number. The wear mechanism was changed from abrasive wear in as received sample to the delamination and adhesive wear in the FSPed and composite samples, respectively.
