Different methodologies are used in practice
to control corrosion.Nano coatings are effectively used
to reduce the impact of corrosive environment due to their various preferences, such
as surface hardness, adhesive quality, long term, as well as high temperature
corrosion resistance, to improve their tribological properties, etc.Furthermore, Nano coatings can be used with thinner, smoother thicknesses, allowing for adaptability in 
equipment design and reduced maintenance and labor costs.Coatings are most commonly used to protect metals from
corrosion.
