    Abstract: A high-temperature-resistant, corrosion-resistant coating, in particular for components of gas turbines, which possesses good corrosion-resistant properties at temperatures between 600 and approximately 1150 DEG C, contains the following elements (in weight percent): 25-40 % nickel, 28-32 % chromium, 7-9 % aluminium, 1-2 % silicon, 0.3-1 % yttrium, the remainder cobalt, at least 5 %, and unavoidable impurities. Various optional constituents may also be present. The properties of the corrosion-resistant coating can be further enhanced by the addition of rhenium even in minute quantities. The preferred range is 4-10 % rhenium. The corrosion-resistant coating is particularly suitable for components in the inlet region of gas turbines with high inlet temperature, which must also operate occasionally at partial load.

    Abstract translation: 耐高温，耐腐蚀的涂层，特别是在600至1150℃之间具有良好耐腐蚀性能的燃气轮机组件中，含有以下元素（重量百分数）：25-40 ％镍，28-32％铬，7-9％铝，1-2％硅，0.3-1％钇，剩余钴，至少5％和不可避免的杂质。 也可以存在各种任选成分。 耐腐蚀涂层的性能可以通过甚至以微量添加铼来进一步提高。 优选的范围是4-10％的铼。 耐腐蚀涂层特别适用于具有高入口温度的燃气轮机入口区域中的组件，这也必须在部分负荷下偶尔运行。
