    • A compressor for a gas turbine has, on the surfaces of its components, in particular of its blading, a coating for protecting the surfaces from erosion. The coating has at least two layers or a plurality of pairs of layers formed from amorphous carbon or a plasma polymer, the layers having an inherently high hardness, and the outermost layer of the coating having hydrophobic properties. Furthermore, the hardness of an inner layer of a pair of layers is higher than the hardness of an outer layer. The coating is particularly suitable for the avoidance of drop impingement erosion caused by liquid drops, erosion caused by solid particles, such as ice, and contamination caused by deposition of dust particles and constituents which are dissolved in liquids. The coating prolongs the service life of the components and increases the power of the turbine.
    • 用于燃气轮机的压缩机在其部件的表面上特别是其叶片具有用于保护表面免受侵蚀的涂层。 该涂层具有由无定形碳或等离子体聚合物形成的至少两层或多层,这些层具有固有的高硬度,并且涂层的最外层具有疏水性。 此外,一层的内层的硬度比外层的硬度高。 涂层特别适用于避免由液滴引起的液滴冲击侵蚀,固体颗粒如冰引起的侵蚀,以及溶解在液体中的灰尘颗粒和成分沉积引起的污染。 涂层延长了组件的使用寿命,并增加了涡轮机的功率。
