As a promising, environmentally friendly alternative for the toxic and carcinogenic chromate conversion surface finishing, zeolite coatings on various metal alloys have shown excellent corrosion resistance, strong adhesion to substrates, and extraordinary thermal and mechanical properties. This review summarizes recent technological advances of zeolite corrosion-resistant coatings from the conventional hydrothermal in situ synthesis method to the newly developed ambient pressure deposition process. The topic of zeolites as smart inhibitor pigments is also discussed. Future perspectives of zeolite corrosion-resistant coatings are envisaged at the end of this review.
