Investigational study of mwcnt’s/silicon oxide nanoparticles/epoxy resin nanocomposite coating on mild steel for anticorrosion and mechanical properties

Abstract

Weathering of mild steel known as corrosion, affects the life span of engineering structures adversely. An attempt to enhance the durability of structure using Nanotechnology carried out in the present experimental work. Multi- Walled Carbon Nano Tubes were prepared by CVD method. For better dispersion of Multi- Walled Carbon Nano Tubes (MWCNT’s) and Silicon Oxide Nano particles were simultaneously ultrasonicated. The MWCNT’s/ SO/ Epoxy Nano composite coating effect on mild steel for corrosion behavior and mechanical properties were investigated. The anticorrosion property of the Nano composite coating was determined by immersion as well as salt spray method. Mechanical properties like tensile strength and scratch hardness were evaluated to compare with the plain mild steel and neat epoxy coated mild steel. For surface characterization, FESEM was conducted. The addition of MWCNTs and Silicon Oxide Nano particles in Epoxy resin improves the anticorrosion and mechanical properties of mild steel. © IJSTR 2020.
