ABSTRACT:
A bucket for an adjustable turbine guide baffle system for gas turbines is formed of an alloy material comprised of a dispersion-strengthened Fe-Cr-Al alloy containing 64.5-75.5% by weight of Fe, 15-25% by weight of Cr, 3-8% by weight of Al, 0.1-1% by weight of Ti, 0-3% by weight of Co, 0.1% by weight of Y or Ce, and 0.1-1.5% by weight of yttrium oxide or aluminum oxide. The bucket has a shank which is under friction stress in the guide baffle system and which is coated with a layer of slip-providing material that contains 90-100% by weight of nickel oxide and 0-10% by weight of one or more oxides of chromium, aluminum, zirconium, titanium, iron, manganese, or magnesium.
