Abstract
The present invention provides parts of a rotation machine which effectively prevent particulates, such as silica, iron oxide, and other particles, contained in a gas to adhere to the rotating machines which work with the gases containing the particulates. An intermediated metal-plated film and a plated film containing fluorocarbon polymer particles provided on the intermediate metal-plated film are deposited on the surfaces of moving blades used in a steam turbine. The plated film containing the fluorocarbon polymer particles includes fluorocarbon polymer particles made of any of Ni-based metals and a plated matrix, and some of the fluorocarbon polymer particles are exposed at the surfaces of the plated matrix.
