Abstract

The corrosion and abrasion performance of flue gas heat exchangers is a prominent research focus in the field of industrial flue gas waste heat recovery. In this study, we have developed a multi-layered composite coating containing fluorographene and carborundum fillers, which exhibits excellent anti-corrosion and wear-resistant properties. Electrochemical and abrasion experiments demonstrate that the multi-layered composite coating effectively improves both the corrosion resistance and the mechanical properties of the material. The structure and preparation of this multi-layered composite coating provide a novel approach for design and application of advanced coatings for highly corrosive and dusty flue gas waste heat recovery.
