Comparison of adhesion properties aluminium, stainless steel and mild steel substrate coated with metallic cerium

Organic coatings, while initially protective, degrade over time due to environmental exposure, needing periodic reapplication and possibly containing harmful substances. Cerium conversion coatings, on the other hand, provide a greener and safer option that adheres strongly to metals such as aluminium, magnesium, and zinc, improving corrosion resistance and durability. The purpose of this study is to evaluate the adhesion qualities of metallic cerium coatings on substrates such as aluminium, stainless steel, and mild steel. Surface preparation procedures specific to each substrate were used, and adhesion strength was measured using established methods. X-ray fluorescence (XRF) investigation aided in the identification of certain alloy types. The experimental design and data analysis used ANOVA to determine the significant effect of substrates on adhesion strength. The results show that cerium coatings have the potential to improve adhesion and performance in a wide range of industrial applications. This study provides important insights into optimising coating processes and increasing material durability.
