摘要： Anti-corrosion ceramics comprising a substrate of at least one kind of silicon-containing ceramics selected from a silicon nitride, a silicon carbide and Sialon, and a surface protection layer formed on the surface of the substrate, wherein the surface protection layer comprises a zirconium oxide stabilized with an element of the Group IIIa of periodic table, and the total amount of Al and Si in the surface protection layer is suppressed to be not larger than 1% by mass. Particularly, the surface layer has a thickness of from 5 to 200 &mgr;m and a porosity of 5 to 30%. The anti-corrosion ceramics exhibits a high resistance against the corrosion due to the water vapor of high temperatures in a region of not lower than 1000° C., and can be preferably used as parts of internal combustion engines such as parts of gas turbine engines, like a turbine rotor, nozzles, a combustor liner and a transition duct.
