In this research, surface composite layers containing nano sized TiB2, Al2O3-TiB2, ZrO2 and CNT particles have been fabricated on Aluminum alloy substrates by friction stir processing. The effects of different processing variables such as number of passes and strengthening particle distribution, hardness, and wear properties of surface nano...

We investigated film thickness effects of sulfuric acid anodized aluminum when galvanically coupled with carbon fiber reinforced plastic（CFRP）. The CFRP was electrically to alloys 1050, 5052, 6061, and 7075 in 3.5 wt.% NaCl solution at 35 ℃. Galvanic current passing from the 1050 6061 decreased as anodic oxide thickened. For galvanic between 5052 CFRP, elapsed time until corrosion density value...

Aluminum-magnesium-silicon alloys are widely used in wide rage of engineering applications because they have moderate corrosion resistance, excellent formability, and high specific strength. The combined effect quenching media aging time on behavior, mechanical properties, microstructure 6061 Al alloy was investigated. Potentiodynamic polarization technique employed to study the behavior 3.5 %N...

Hot deformation behavior of a medium Cr/Mn Al6061 aluminum alloy was studied by isothermal compression test at temperatures range of 320 to 480 °C and strain rates range of 0.001 to 0.1 s −1. The true stresstrue strain curves were analyzed to characterize the flow stress of Al6061. Plastic behavior, as a function of both temperature and strain rate for Al6061, was also modeled using a hyperboli...

Semisolid processing is one of the modern routes in sound and near net shape parts production.  Preparation of semisolid slurry using a cooling slope is increasingly becoming popular, primarily because of its simplicity in design and ease of control of the process. In this research, the microstructures of Al6061 semisolid alloy cast via a miniature cooling slope were investigated. The propertie...

Burr formation is a common and undesirable phenomenon in metal cutting operations, reducing the quality, accuracy, functionality of component. In micromachining, burrs are smaller but comparable to feature size difficult remove. Most traditional deburring operations cannot be applied micromachined components without proper scaling, as on part very small prone damage. Ultrasonic energy widely us...
