Rotatable machine and parts thereof

The present invention provides parts of a rotary machine provided which, effectively avoids adhesion of particles, such as silica, iron oxide and other particles that are contained in a gas in the rotary machines, which operate with the gases containing the particles , A metal-clad intermediate film 11 and the plated film 12 containing the fluorocarbon polymer particles and which is provided on the metal intermediate plated film 11 are formed on the surfaces 1, 1a, 1b, 1c, of the blades 23 in a steam turbine be used deposited. The plated film 12 comprises fluorocarbon polymer particles 13P, which are made of any Ni-based metal, and a plated matrix 13M, and some of the fluorocarbon polymer particles 13P are exposed from the surfaces of the plated matrix 13M.
