| 摘要 |
The invention relates to the widest variety of workpieces for high-temperature use. The workpieces are given a coating layer system making it possible to combine certain desired surface properties with certain desired bulk properties of the basic material in a favourable manner. The invention also relates to a process consisting of a combination of individual steps making it possible to produce the workpiece of the invention in the best possible way. The workpiece of the invention may be used to form a dipolar separator and an electrolyte substrate in high-temperature solid-electrolyte fuel cells, a gas turbine blade, a steam turbine blade, a combustion chamber wall, a heating boiler wall, an injection nozzle, a measuring probe casing or an optical component. |
