Abstract: Electroplating plays a significant role in the automotive decorative field, but it is highly energy-consuming, heavily polluting, and poses serious hazards to human health. This study employs intermediate frequency magnetron sputtering technology to deposit Cr and chromium oxide films on ABS substrates, and utilizes SEM, XRD, and XPS to characterize the prepared samples. The research results indicate that as the sputtering time increases, the films are primarily composed of amorphous Cr 2 O 3 and CrO 3. By controlling the thickness of the top chromium oxide film, films displaying various colors such as red, orange, yellow, and green were successfully prepared. Tests on the film hardness and adhesion showed that the hardness can reach H level, and the adhesion is 0 level, both meeting industry standards. This study demonstrates the feasibility of achieving decorative coatings for automotive interior parts through green processes, while also providing significant reference value for the field of polymer metallization and decoration.
