Study and Computational Modeling of Nano Coating to Protect Products from Atmospheric Corrosion

The atmospheric corrosion rate of materials changes based on different environmental conditions including time to be exposed to wet condition, relative humidity, surrounding temperature, and impurity of the air. The adhesive bond is relatively weak in conventional surface coating process which may lead the separation of these coatings and reduction of effective coating lifecycle. Some conventional surface coatings even could not well protect materials from flaking and peeling of coating material in moderate corrosion and mild abrasive conditions. The nanocoating technology has been developed in past years to improve coating’s anti-corrosion performance. So far there are few feasible computational modelling and simulation tools that can be effectively applied to study and validate the performance of nanocoated materials. To help understanding the nanocoating mechanism and anti-corrosion performance, this paper studies the nano coating process through fundamental analysis, computer-aided simulation, and prototyped sample testing. The analytic and prototype testing results in this research conclude that the nanocoated material surfaces have been more protected from atmospheric corrosion than other coatings and the effective lifecycle of nanocoating is significantly longer than current existing coatings. Also, compared with conventional coating methodologies, nano coating technology provides more environmental protections than others. All these important findings and results are studied, analysed, and discussed in this paper to provide better understanding of anti-corrosion mechanism and superior performance of nanocoatings.
