Vibration under high flow conditions is a significant issue and can lead to cracking and damage of the structural material. Also, recently, due to the thinning phenomenon in the carbon steel pipe, the pipe thickness has been reduced, which may cause problems.

- a method for producing a corrosion-resistant member characterized in that it includes a step of pre-adhering titanium oxide to the surface of the constituent material, and then performing a high-temperature treatment in the presence of ions of the transition metal M thereafter or simultaneously. Is achieved.

- the thickness of the titanium composite oxide film is 0.1 to 50 ⁇ m.
- the titanium composite oxide coating because it binds chemically plant structural material surface complexed, even compared to TiO 2 which is physically attached to the film It is possible to suppress fluid accelerated corrosion that is unlikely to occur and may occur in the part where the high-temperature fluid flows, and therefore, it is possible to suppress fluid accelerated corrosion such as corrosion elution without injecting chemicals.

- FIG. 2 shows the result of a corrosion test using the test piece made of the corrosion-resistant member 3 shown in FIG. 1 under the conditions of dissolved oxygen of less than 5 ppb and a flow rate of 15 m / sec.
- the titanium composite oxide film is combined and chemically bonded to the surface of the plant structural material. Even if compared with TiO 2 that has been processed, peeling of the film is less likely to occur, and it is expected to exhibit a corrosion-inhibiting effect, in particular, a thinning-inhibiting effect due to flow accelerated corrosion that may occur in a portion where a high-temperature fluid flows. it can. Thereby, it becomes possible to aim at reduction of the trouble accompanying the thinning of piping and periodic inspection.
- the titanium composite oxide is shown as an example of FeTiO 3 , but it may be expressed by the molecular formula MTiO 3 and M may be a transition metal such as NiTiO 3 , and may be divalent as a transition element in addition to Fe and Ni.
- M may be a transition metal such as NiTiO 3 , and may be divalent as a transition element in addition to Fe and Ni.
- V, Cr, Mn, Co, Cu, Zn, Mo, Ru, Pd, and Rh are also possible.

- FIG. 3 shows a block diagram (flow diagram) of a process for forming a titanium composite oxide on the surface of carbon steel.
- the carbon steel surface is first polished or chemically cleaned to expose the new surface (the material surface is renewed (step S1)).
- the attachment method may be either spray application or a method of introducing titanium oxide under high temperature conditions and bringing it into contact with the surface of the structural material.
- the dissolved oxygen concentration is set to less than 10 ppb, for example, 2 ppb
- the temperature of the aqueous solution is set to 80 ° C. or more and 500 ° C. or less, for example, 150 ° C.
