A chromium cermet coating, about 150 {micro}m thick, was formed on carbon steel with the gas transport self-propagating high-temperature synthesis (SHS) coating process. The present paper is concerned with the preparation method, property evaluation, and abrasive wear behavior of the SHS coatings. The experiment reveals that there is excellent adhesion between the coating and the substrate, with less matrix damage and good abrasive wear resistance compared with chemical vapor deposition (CVD)-Cr{sub 7}C{sub 3} coatings. Investigations indicated that an intense metallurgical interaction, gradient composition distribution, and unique forming process are the major reasons for the superior performance of the SHS coatings. It is analytically shown that there is a relationship between the size of the abrasive, the coating thickness, and the abrasive wear resistance.
