Definitions

  • the present invention relates to a method for diffusing and permeating a creep reinforcement material into a heat-resistant metal member, and to a heat-resistant metal member with creep strength enhanced by such a method.
  • US2013/0220523 discloses e.g. in example 4 a 430 steel foil was spray coated with a composition comprising e.g. Cr, Mo and B. Then the sprayed foil was put inside a steel pipe i.e. covered by the pipe. The steel foil was pressed against the pipe and the assembly was heat treated in vacuum under 1190-1225 C for 15 to 30 min.
  • An object of the present invention is to provide a method capable of efficiently diffusing and permeating a material that enhances creep strength (hereinafter referred to as a "creep reinforcement material") into a member manufactured using a heat-resistant metal material (hereinafter referred to as a "heat-resistant metal member”), and to provide a heat-resistant metal member with creep strength enhanced by such a method.
  • the present invention enables provision of a method capable of efficiently diffusing and permeating a creep reinforcement material into a heat-resistant metal member, and provision of a heat-resistant metal member with creep strength enhanced by such a method.
  • Fig. 1 is a schematic diagram illustrating a method for diffusing and permeating a creep reinforcement material into a heat-resistant metal member, to explain an embodiment of the present invention.
  • Fig. 2 is a schematic cross-section illustrating a cross-section of Fig. 1 , to explain an embodiment of the present invention.
  • explanation is of an example of a case in which an already installed (including repaired cases thereof) or unused, or a degraded, high temperature pipe manufactured using a heat-resistant metal material, is employed as a heat-resistant metal member 10, however, there is no limitation thereto.
  • the heat-resistant metal member 10 may be another high temperature member manufactured using a heat-resistant metal material, such as an already installed (including repaired cases thereof) or unused, or a degraded, turbine.

Then a section 25 onto which the creep reinforcement material has been coated or thermally sprayed is covered by a heat-resistant covering member 30, and the heat-resistant covering member 30 is secured so as to make contact with the section 25. Next, the heat-resistant metal member 10 covered by the heat-resistant covering member 30 is heated for a specific duration at a temperature of 1000°C or greater using a heater 40.
  • the heat-resistant metal member 10 coated or thermally sprayed with the creep reinforcement material is covered by the heat-resistant covering member 30 and is heated to a temperature of 1000°C or greater, and thus compressive force acts on the heat-resistant metal member as it thermally expands in a direction toward an outer periphery, restraining thermal expansion of the heat-resistant metal member in the direction toward the outer periphery, and enabling the creep reinforcement material on the surface of the heat-resistant metal member 10 to be efficiently diffused and permeated into the heat-resistant metal member 10.
  • the heat-resistant metal member 10 is a degraded member or an already installed member

  • etching treatment or shot peening and etching treatment, may be performed on the section 25 to be coated or thermally sprayed with the creep reinforcement material prior to coating or thermally spraying the creep reinforcement material on the surface of the heat-resistant metal member 10.
  • Such processing enables work hardening of the surface layer of the heat-resistant metal member 10 to be performed by plastic deformation, enables residual compressive stress to be imparted to the surface of the heat-resistant metal member 10, and enables any oxidized film on the surface of the heat-resistant metal member 10 to be removed.
  • processing to remove (reduce) residual stress may be performed after the heat-resistant metal member 10 covered by the heat-resistant covering member 30 has been heated to a temperature of 1000°C or greater using the heater 40.
  • the heat-resistant metal member 10 may be first cooled to room temperature, then reheated to a temperature of an A 1 transformation point or greater (preferably from 10°C to 100°C above 1000°C) for a specific duration (for example, from approximately several hours to approximately 24 hours).
  • the heat-resistant metal member 10 in order to restrict thermal expansion of the heat-resistant metal member 10 toward the outside in the length direction thereof (in directions toward the ends of the heat-resistant metal member 10) occurring when the heat-resistant metal member 10, which has been coated or thermally sprayed with the creep reinforcement material, is covered by the heat-resistant covering member 30 and heated by the heater 40, the heat-resistant metal member 10 may be secured in sections not being heated by the heater 40, by, for example, two clamps so as to sandwich the section being heated by the heater 40.

  • the creep reinforcement material needs to contain an element which has a melting point of 1000°C or greater and in which precipitation strengthening and solid solution strengthening occur upon heating to a temperature of 1000°C or greater so as to enable creep strength to be enhanced.
