Surface-reformed exhaust gas guide assembly of vgs type turbo charger, and method surface-reforming component member thereof

摘要

A novel exhaust gas guide assembly with an improved high-temperature sliding wear resistance, oxidation resistance, high-temperature strength or the like for a VGS turbocharger is provided. The invention is characterized in that a surface modification is applied to a component member of the exhaust gas guide assembly (A), such as adjustable blades (1), a turbine frame (2), a blade adjusting mechanism (3), or the like.
