    Abstract: A metal coated with ceramic and a method manufacturing the same. The metal contains chromium. A buffer layer is disposed on the metal, and a silicon carbide (SiC) coating layer is disposed on the buffer layer. The buffer layer has a thermal expansion coefficient between those of the metal and the SiC coating layer. The method includes annealing a metal containing chromium to form a chromium oxide layer on the metal, dissolving polycarbosilane (PCS) in a solvent to form a PCS coating solution, coating the chromium oxide layer with the PCS solution, and annealing the to form an SiC coating.
