耐侵蚀和耐腐蚀的涡轮压缩机翼型件及其制造方法
摘要：
本发明涉及耐侵蚀和耐腐蚀的涡轮压缩机翼型件及其制造方法。该翼型件包括具有修改的翼型件表面的涡轮压缩机翼型件。该翼型件表面具有包括牺牲性涂层的翼型件涂层，牺牲性涂层包括Al、Cr、Zn、Ni-Al合金、Al-Si合金、Al基合金、Cr基合金或Zn基合金、Al聚合物复合材料或其组合的层，或者传导性底涂层和布置于该底涂层上的无机基质粘结剂的顶涂层，该无机基质粘结剂具有嵌入在其中的多个陶瓷粒子和传导性粒子。该翼型件涂层还包括牺牲性涂层，其中牺牲性涂层或耐侵蚀性涂层中的一个布置于翼型件表面上，耐腐蚀性涂层或耐侵蚀性涂层中的另一个布置于相应涂层上，其中牺牲性涂层的阳极性比翼型件表面或耐侵蚀性涂层更强。
摘要（英）：

The invention relates to an erosion and corrosion resistant turbine compressor airfoil and a method of making the same. A sacrificial and erosion-resistant turbine compressor airfoil includes a turbine compressor airfoil having a modified airfoil surface. The airfoil surface has an airfoil coating that includes a sacrificial coating comprising a layer of Al, Cr, Zn, an Ni-Al alloy, an Al-Si alloy, an Al-based alloy, a Cr-based alloy or a Zn-based alloy, an Al polymer composite, or a combination thereof, or a layer of a conductive undercoat and an overcoat of an inorganic matrix binder having a plurality of ceramic particles and conductive particles embedded therein disposed on the undercoat. The airfoil coating also includes an sacrificial coating, wherein one of the sacrificial coating or the erosion-resistant coating is disposed on the airfoil surface and the other of the corrosion-resistant coating or the erosion-resistant coating is disposed on the respective one, and wherein the sacrificial coating is more anodic than the airfoil surface or the erosion-resistant coating.
