    摘要： A solid particle erosion resistant surface treated coat is provided by which a solid, particle erosion resistance is largely enhanced and a rotating member is given with an oxidation resistance without deteriorating a fatigue strength. Also, a rotating machine, such as a steam turbine, axial compressor or the like, applied with this coat is provided. The solid particle erosion resistant surface treated coat comprises a nitrided hard layer formed on a surface of base material and a PVD (physical vapor deposition) hard layer of at least one layer formed on the nitrided hard layer by a PVD method. The nitrided hard layer has a thickness of at least 30 μm. The PVD hard layer has a total thickness of at least 10 μm. Deformation of the base material by collisions by solid particles is prevented and crack of the coat comprising the nitrided hard layer formed on the base material and the PVD hard layer formed on the nitrided hard layer is prevented. Thereby, the solid particle erosion resistance is secured, life of the solid particle erosion resistant surface treated coat can be elongated and the oxidation resistance and fatigue strength are enhanced.

    摘要翻译： 提供固体颗粒侵蚀表面处理涂层，通过该涂层可大大提高固体，耐颗粒侵蚀性，并且在不降低疲劳强度的情况下赋予旋转构件耐氧化性。 此外，还提供了涂有该涂层的旋转机械，例如蒸汽轮机，轴向压缩机等。 固体颗粒侵蚀表面处理涂层包括在基材表面上形成的氮化硬质层和通过PVD方法形成在氮化硬质层上的至少一层的PVD（物理气相沉积）硬质层。 氮化硬质层的厚度至少为30μm。 PVD硬质层的总厚度至少为10um。 防止了通过固体颗粒的碰撞使基材变形，并且防止了形成在基材上的氮化硬质层和形成在氮化硬质层上的PVD硬质层的涂层的裂纹。 由此，确保了耐固体颗粒侵蚀性，可以延长固体颗粒耐腐蚀表面处理涂层的寿命，提高耐氧化性和疲劳强度。
