  • Protection of metallic surfaces against thermally-inducted wrinkling (rumpling)
    Publication number: 20070128458
    Abstract: Gas turbine blades in power units or for electric power generation are subject to high thermal stress which is cyclic in nature and leads to a roughening of the metallic surface. According to the invention, the metallic surface is provided with a thin ceramic coating having a thickness of less than 50 ?m. Roughening can be avoided thereby.
