Abstract

This paper aims to study the effect of adding different SiC content on the wear performance of Al₂O₃-TiB₂-SiC ternary composite coatings produced by the air plasma spraying process. The study used SHS powders as primary materials, consisting of H₃BO₃, Al, and TiO₂, and 5, 10, and 15 Vol.% SiC. The microstructure and wear specifications of the coatings were characterised using FESEM, microhardness, and pin-on-disk methods. The results showed that the addition of SiC led to higher hardness and lower wear track width and rate compared to Al₂O₃-TiB₂ composite coatings. The best wear behaviour was observed in Al₂O₃-TiB₂-10%SiC and 15 wt% SiC composite coatings. The main wear mechanisms were found to be brittle fracture, delamination and adhesive for all samples.
