Advanced corrosion resistant coatings for steels

Corrosion as a foe is a menace for economic growth no matter whether it is developed nation or developing nation like India. Corrosion is a major problem plaguing various industries. In order to overcome this issue, the industries rely on metallic (Zn, Cr etc.) and polymeric (polyurethane, epoxy, etc.)

coatings.Currently, smart, self-healing coatings are the state-of-the-art option to inhibit cut-edge corrosion and to enhance the lifetime of coatings.

The

aim of the proposal is to develop smart composite coatings using mesoporous (container) materials followed by loading with inhibitor and incorporation in

polymer/metal coatings.

The objectives would involve the i) synthesis and characterization of various container materials, ii) studying the loading and sustained/slow release of the inhibitors as an effect of external stimulus (pH, temperature etc.), iii) investigation of multi-functional performance and the corrosion protection performance. The outcome of the research would render an alternative coating to toxic chromate- or conventional simple-functional polymer- coatings.

The fundamental understanding of the developed coatings can be easily scaled-up to industrial level and tested for its performance in

real-time applications.
