Sustainable Nanocomposites for Corrosion Control

Corrosion is a natural process that causes the gradual corrosion of metals and alloys through reactions in the environment, giving rise to great problems in a wide variety of sectors. This process brings about great economic losses, reduces material life, and creates safety issues, especially in instances where the metals react with corrosive substances to give stable compounds such as oxides and sulfides. Since corrosion is basically electrochemical in nature, it occurs due to anodic oxidation and cathodic reduction; hence, this process is a serious menace to the integrity of the structure as well as the aesthetic excellence of the material elements. Economic losses attributed to corrosion are enormous, whereby more than $2.5 trillion is lost annually in infrastructure and utility sectors, transportation, besides in manufacturing segments, especially for the oil and gas sector, which costs approximately $1.372 billion per year due to corrosion in pipelines. This represents one of the important benefits: research even shows that with existing prevention methods, corrosion-related costs might be lowered between 15% and 35%. Sustainable nanocomposites, developed and eventually combining improved resistance with environmental sustainability, make it feasible to prevent corrosion. This study has discussed the influence of corrosion on a number of industries and illustrated the increasing importance of nanocomposite materials in increasing corrosion control while reducing the negative environmental effects of established treatments.
