An Assessment to Replace Conventional Mild Steel with Hybrid Nanocomposite Steel to Improve Mechanical and Anticorrosive Properties

Abstract

Multi Walled Carbon nanotube’s (MWCNT’s) are tiny tube’s made of carbon atoms with a few nanometers in diameters and several microns in length. After Iijima's discovery in 1991, regarding the form of carbon atoms, a great deal of interest was drawn to utilize of MWCNTs outstanding chemical and physical properties such as high Young’s tube, tensile strength, excellent thermal and electrical conductiveness. Recently, MWCNT’s have been used in various fields, due to high chemical, thermal and mechanical properties. In the field of composite structures in which MWCNT’s are not only included in a matrix as an insulation but also to obtain other chemical and physical properties like corrosion resistance, mechanical properties and electrical conductivity. Multi walled carbon nanotube’s along with other nanoparticle’s such as grapheme oxide, zinc oxide, silicon oxide and cerium oxide nano particles which have been proven to have better mechanical and anticorrosion properties incorporated independently with MWCNT’s to develop hybrid nanocomposite’s offering a new composite material generation. Nanostructured composites enhance their sensitivity and efficiency when used in corrosive environment. In this research study an attempt is made to introduce new hybrid nanocomposite steels which can have higher mechanical and anticorrosive properties.
