PROTECTION OF METALLIC SURFACES AGAINST THERMALLY-INDUCED WRINKLING (RUMPLING) |
| 摘要 |
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 mum. Roughening can be avoided thereby. |
