摘要： A composite coating for use on semi-conductor processing components, comprising a refractory metal carbide coating with its surface modified by at least one of: a) a carbon donor source for a stabilized stoichiometry, and b) a layer of nitride, carbonitride or oxynitride of elements selected from a group B, Al, Si, refractory metals, transition metals, rare earth metals which may or may not contain electrically conducting pattern, and wherein the metal carbide is selected from the group consisting of silicon carbide, tantalum carbide, titanium carbide, tungsten carbide, silicon oxycarbide, zirconium carbide, hafnium carbide, lanthanum carbide, vanadium carbide, niobium carbide, magnesium carbide, chromium carbide, molybdenum carbide, beryllium carbide and mixtures thereof. The composite coating is characterized as having an improved corrosion resistance property and little emissivity sensitivity to wavelengths used in optical pyrometry under the normal semi-conductor processing environments.
