Analysis of Mechanical Properties and Morphological Study of Coated Ceramics Using Multiwall Carbon Nanotubes with Aluminium Alloy

Abstract

Aluminium alloy(A 356) has improved properties such as tension and elongation butit is decreased in hardness property compared to ceramics and therefore silicon carbideparticle (SiCp) is added with aluminium alloy to increase its hardness. Silicon Carbideparticle is abrasive and hence having poor interfacial bonding between ceramics andaluminium, so that the surface of the ceramics is coated with Multi Wall Carbon Nano Tubes(MWCNT). In this paper 10% of SiCp is taken for the experiment and coated with 1.5%, 2%,2.5% of MWCNT and this coated SiCp mixed with molten A 356 using stir casting method.The prepared castings were mechanically tested using Universal Testing Machine (UTM),Vickers hardness Testing Machine, Impact Testing Machine and Optical Microscope andtheir mechanical properties and morphological characteristics were studied
