PROBLEM TO BE SOLVED: To provide an exhaust guide assembly for a new VGS turbocharger, having improved sliding performance of a constituent member, under a high temperature and exhaust gas atmosphere. SOLUTION: High temperature durability is improved, by constituting the 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 - chromium based heat resistant member and forming a coat of chromium carbide with a substantially single phase on the surface of the member. |
