The effect of Sol-Gel technique on the aluminium-SiCp composite
Due to the low reactivity between the silicon carbide particulate (SiCp) and Aluminium (Al) interface bonding strength, SiCp is treated by applying a coating on its surface. The objective of this paper is to study the effect applying ceramic sol coating, which is silica sol via sol gel technique o...
