<p>PROBLEM TO BE SOLVED: To provide an exhaust guide assembly for a new VGS turbocharger, having improved high-temperature wear resistance, oxidation resistance, and hot hardness, or the like. SOLUTION: The high-temperature wear resistance, oxidation resistance, and hot hardness at elevated temperatures, or the like are improved by composing a constituent member of the exhaust guide assembly A, such as a variable blade 1, a turbine frame 2 or the varying mechanism 3 by a nickel-containing heat resisting member or an austenitic heat resisting member containing nickel and forming a coat of chromium carbide on the surface of the member.</p> |
