Investigation of Water-in-Biodiesel Emulsion Characteristics Produced by Ultrasonic Homogenizer

INVESTIGATION OF TRIBOLOGICAL CHARACTERISTICS OF AL/NANO SiO2NANOCOMPOSITES PRODUCED BY ACCUMULATIVE ROLL BONDING (ARB) PROCESS

Accumulative roll-bonding process (ARB) is an important severe plastic deformation technique for production of the ultrafine grained, nanostructured and nanocomposite materials in the form of plates and sheets. In the present work, this process used for manufacturing Al/SiO 2 nanocomposites by using Aluminum 1050 alloy sheets and nano sized SiO 2 particles, at ambient temperature. After 8 cycle...
