|1. (WO2018038151) MULTILAYER STRUCTURE AND MACHINE COMPONENT HAVING MULTILAYER STRUCTURE|
|Applicants:||MITSUBISHI HEAVY INDUSTRIES COMPRESSOR CORPORATION
|Title:||MULTILAYER STRUCTURE AND MACHINE COMPONENT HAVING MULTILAYER STRUCTURE|
Provided are: a multilayer structure which has achieved a good balance between erosion resistance and fouling resistance; and a component for rotary machines, which has this multilayer structure. A multilayer structure 1 according to the present invention is characterized by having: a nitride layer 5 which is formed on the surface of a base material 3 by subjecting the base material 3 to a nitriding treatment; an intermediate layer 6 which is formed on the surface of the nitride layer 5; and a DLC layer (diamond like carbon layer) 7 which is formed on the surface of the intermediate layer 6. This multilayer structure 1 is applicable to a component that is used in a rotary machine such as a steam turbine.
