Investigation of the microstructure-hardness and wear performances of hybrid/composite materials Al2O3/SiC particle reinforced in AA 7075 matrix

As a result of advances in science and technology, the importance metal matrix composite materials is increasing gradually today. However, many studies, production carried out with monotype ceramic particle reinforcement. In this study, production, microstructure-hardness, wear performance composite-hybrid that had AA 7075 aluminum powder were reinforced by SiC Al2O3 particles at different ratios examined. The prepared Matrix reinforcement mixtures mixed for half an hour three-axis Turbula T2F type mixer then, pressed unidirectionally cylindrically under pressure 700 MPa. samples sintered 1 h temperature 600oC argon atmosphere. Microstructure examinations using SEM (Scanning Electron Microscope) optical microscope devices, while hardness measurements obtained as Brinell measurement. Wear test tested Pin-on-disk device 10 N load 500 rpm rotation speed depending on distances 1000, 1500 2000 m. It was observed increased amount increased. tests, hybrid composites, compared to single-phase weight losses increase amount.
