Abstract
Abstract This paper summarizes the anti-corrosive and anti-erosive properties of water-ethylene glycol based commercial coolant dispersed with nanomaterials. Multiwalled carbon nanotubes (MWCNTs), silver nanoparticles (Ag) and nanosized alumina particles (Al2O3) are dispersed in 0.5% weight in automotive coolants and tested for anti-corrosive properties as per ASTM standards. Prior to dispersion, the nanomaterials are surface modified to get good stability in coolant solutions. The corrosion resistance is measured in terms of weight loss of materials that is commonly used in automotive systems. It is found that oxidized MWCNTs are suitable to automotive systems while silver and Al2O3 nanoparticles are found to be deleterious in nature.
