ABSTRACT: A smart hybrid conversion coating has been developed. Modifications of coating solutions with
poly-hydroxyl organic materials to reduce the usual mud cracking pattern characteristics of
chromate conversion coatings (CCCs) and improve its ability to release inhibitors to corroding
sites have been achieved. The smart functionalised chromate conversion coating (SFCCC), developed
on aluminium substrate has undergone laboratory checks and commercial runs under factory
conditions confirmed its potency in improving corrosion resistance and paint adhesion to
metal surfaces. In-service performance of the coating in the past three years is excellent.
