This review is done essentially to study results in the field of synthesis and characterization of SiC reinforced Al-SiC composite coatings using thermal spray process. SiC reinforced composite coatings produced by thermal spray process are being developed for a wide variety of applications, e.g. aerospace, automotive, structural and industrial. It is anticipated that, if properly deposited, Al-ceramic coatings could also provide improved properties like wear resistance and thermal barrier coatings. These results clearly demonstrate that the significant improvement in coating performance can be achieved by utilizing proper thermal spray conditions and SiC % in composite coatings. This paper presents a critical review on SiC reinforced Al-SiC composite coatings using thermal spray by various researchers in past years. The researcher’s findings with necessary parameters for achieve good Al-SiC composite coatings are given.
