Anodic oxidation is used to improve the wear resistance and surface properties of aluminum alloys. In this study, effect two different anodic (hard anodizing phosphoric coating) on 2017A alloy as a model aircraft engine piston was investigated. order determine oxidation, microhardness, friction coefficient, resistance, vibration, worn images samples were evaluated. It concluded that significant...

A borocarburized layer was successfully fabricated on the surface of Q235 low-carbon steel via double glow treatment to improve wear resistance at elevated temperature. The phase composition and microstructure were investigated by XRD SEM. microhardness from substrate detected. And tribological behaviors under dry-sliding against ZrO2 ball three temperatures. results indicate that consists an o...

In this study, an AA7075 composite material with a varying weight percentage of silver and zirconium oxide reinforcement is examined in terms its properties. Reinforcement quantities ranging from 0, 4, 8, 12, 16 wt % were combined the matrix using in-situ technique stir casting field. Tensile, mechanical hardness, compressive strength assessed accordance standard. The X-ray diffraction EDS util...
