Abstract

In this work, the surface of Q235 steels was treated by air plasma to improve the adhesion between epoxy coatings and Q235 steels. The epoxy coatings were prepared through the electrostatic spraying. The disbonding test was used to characterized the adhesion strength of epoxy coatings. Meanwhile, the chemical and physical properties of Q235 steels matrix surface before and after treatment were investigated using XPS, AFM and FTIR. The results showed that both the surface roughness and surface free energy of Q235 steels have an obvious increase after the air plasma treatment. In addition, some polar groups were introduced on the surface of matrix. The adhesion strength of epoxy coatings was enhanced from 1.67ñ0.48MPa to 4.25ñ0.58MPa.
