Optimization of Friction Stir Processing Parameters of Aluminum Alloy Reinforced with Hybrid Nanoparticles Using the Taguchi Method

Abstract This study deals with the selection of optimum parameters for friction stir processing Al alloy 6061-T6 reinforced a hybrid nanoparticle (B4C and SiO2) in terms their effect on mechanical properties (hardness, tensile strength, wear resistance) using Taguchi method. work was carried out under four each one running three levels; rotational speeds ( 800 , 1000 1200 ) rpm, travel 10 20 30 mm/min, holes depth 2 2.5 3 mm mixing ratio (SiO2/B4C) nanoparticles 1/1 1/2 1/3 ), L9 34 orthogonal array. Tensile strength microhardness tests were conducted to evaluate properties, addition resistance test which is pin-on-disk device. The microstructure examined by optical microscopy, field emission scanning electron x-ray diffraction analysis. It found that highest 223 MPa at rpm speed, mm/min traverse depth, ratio, hardness reached 155 HV, then decreases direction thermomechanically affected zone (TMAZ), heat (HAZ), base material linear hole (B4C/SiO2) nanoparticles. behavior mild type or an oxidative low loads 5 N became severe metallic higher fixed sliding time speed. (ANOVA) table has been used determine parameter most significant MINITAB software.
