Hochtemperaturkorrosionsbeständige Legierung, thermische Schutzschicht mit metallischer Verbindungsschicht und Gasturbine mit Schutzschicht aus dieser Legierung

摘要

A high temperature corrosion resistant alloy composition comprising, in addition to Ni, 0.1 to 12% by weight of Co, 10 to 30% by weight of Cr, 4 to 15% by weight of Al, 0.1 to 5% by weight of Y, and 0.5 to 10% by weight of Re. The high temperature corrosion resistant alloy composition has an excellent oxidation resistance and ductility and is suitable for use in a bonding layer of a thermal barrier coating material.
