PURPOSE:To extend the life of machinery by improving corrosion resistance and durability, by constituting machinery for handling halogen compound by forming a coating layer on the inner surface metal of metal machinery by the thermal spraying of a substance such as a thermal spraying metal or oxide thereof. CONSTITUTION:A coating layer is formed on the inner surface metal of metal machinery handling a halogen compound by the thermal spraying of at least one or more of a substance selected from a thermal spraying metal, oxide thereof, carbide thereof and nitride thereof to form machinery for handling the halogen compound improved in corrosion resistance. As the thermal spraying metal, there are nickel, cobalt, chromium, molybdenum, tungsten or platinum and, as the thermal spraying coating method, a flame spraying method or an arc spraying method can be employed. The thickness of the flame spraying layer of the flame spraying metal is pref., 20-5,000mum. |
