抑制活性元素过度掺杂的MCrAlRe/RexOy涂层材料、涂层及制备方法
摘要：
抑制活性元素过度掺杂的MCrAlRe/RexOy涂层材料、涂层及制备方法，属于表面工程技术领域。抑制活性元素过度掺杂的MCrAlRe/RexOy涂层材料，M是Ni、Co、Fe中的一种或几种，Re是活性稀土元素Y、Zr、Ti、Ru、Hf中的一种或几种，所述MCrAlRe/RexOy涂层材料含有MCrAlRe和稀土氧化物RexOy，重量百分比为：RexOy粉末，0.01-6％；MCrAlRe粉末，余量。Re向氧化铝层中的扩散速率显著降低，有效避免活性元素过度掺杂，极大提高了涂层使用寿命，在航空发动机或燃气轮机的风扇、压气机叶片、涡轮叶片以及轧辊部件的高温氧化及热腐蚀防护领域具有良好应用前景。
摘要（英）：

The invention provides a MCrAlRe/RexOy coating material capable of inhibiting over-doping of active elements, a coating and a preparation method thereof, and belongs to the technical field of surfaceengineering. According to the MCrAlRe/RexOy coating material capable of inhibiting over-doping of the active elements, M is one or more of Ni, Co and Fe, Re is one or more of active rare earth elements Y, Zr, Ti, Ru and Hf, and the MCrAlRe/RexOy coating material contains MCrAlRe and rare earth oxide RexOy, and comprises 0.01%-6% of RexOY powder and the balance MCrAlRe powder. The diffusion rate ofthe Re to an aluminum oxide layer is remarkably reduced, the excessive doping of the active elements is effectively avoided, and the service life of the coating is greatly prolonged, and the coatingmaterial has a good application prospect in the fields of high-temperature oxidation and thermal corrosion protection of a fan, a gas compressor blade, a turbine blade and a roller component of an aero-engine or a gas turbine
