Definitions
- the invention relates to a method for the surface treatment of steel, in particular stainless steel, and / or of a nickel alloy.
- the invention also relates to uses for such a method and a steel or nickel alloy produced by such a method.
- the steel or the nickel alloy are, for example, of the type Incoloy 800, Inconel 600 or the like.
- the method can be used in nuclear technology to reduce the later activity absorption (contamination) of components of the primary circuit of water-cooled nuclear power plants before new installation or after decontamination.
- oxide layers form on the wetted surfaces, which largely consist of zirconium alloys and austenitic chromium-nickel steels (so-called stainless steel), by reaction with the hot water and / or steam. Some of these oxide layers get into the water cycles through solution or erosion and can be activated in the neutron field. If the activated corrosion products are stored outside of the reactor core on surfaces of components in oxide layers present there or as particles on them, these components are radioactively contaminated.
- Components in the pressurized water reactor that are at risk of contamination are mainly main coolant pumps and steam generators, in older boiling water reactors with external circulation, they are Recirculation lines and the reactor water purification system.
- the object on which the invention is based is that of developing a method which has the following properties:
- the invention is also based on the object of specifying suitable uses of the method and a steel or a nickel alloy to be obtained with such a method.
- the surface of the steel be used with peroxide or with a water-peroxide mixture or with treated with a peroxide solution.
- peroxide also stands for a water-peroxide mixture or a peroxide solution.
- Peroxide can always take the place of “hydrogen peroxide” and vice versa.
- the treatment is carried out, for example, under water and, for example, by adding hydrogen peroxide to the water.
- the process for the surface treatment of stainless steel and / or nickel alloys, for example of the type Incoloy 800, Inconel 600, and the like, which are used particularly in steam generators of pressurized water reactors provides that the surface to be treated is initially treated using generally customary techniques, such as, for example through chemical treatment, is cleaned and degreased.
- the actual treatment can be carried out with a peroxide solution with a peroxide concentration of 0.1 to 200 mmol H 2 0 2 in, for example, pure or deionized water. This treatment can be done in an open or closed system.
- concentrations higher than 10 mmol H 2 0 2 are not used, but can nevertheless be used, but no longer bring any significant advantages in the sense of the invention, since excess hydrogen peroxide is rapidly decomposed thermally and catalytically, ie remains ineffective for the desired layer formation .
- the peroxide solution is e.g. a solution of peroxide in pure or deionized water.
- the object of specifying a suitable use for the method is achieved according to the invention by the combination of features of claims 13 or 14.
- the method is used to treat surfaces wetted in water-cooled nuclear power plants, which are largely made of stainless steels and / or nickel alloys, for example of the type Incoloy 800, Inconel 600, or the like exist, which are used particularly in steam generators of pressurized water reactors and which in the past have led to the problems mentioned at the outset due to contamination.
- FIG. 1 serves as an example of this behavior, where the deposition behavior of Co-58 is shown under primary water conditions of a boiling water reactor on steel material number 1.4571 (X10CrNiMoTil810).
- composition and structure of the layer produced by means of hydrogen peroxide differs fundamentally from that formed atmospherically or only with hot water. While mainly chromium-rich oxide layers are formed during atmospheric oxidation and mainly nickel spinels are formed in hot water without hydrogen peroxide, almost pure iron III oxides are formed with hydrogen peroxide. Oxide layers without hydrogen peroxide form little or no protection against further oxidation in hot water / steam (the spinel layers continue to form), while layers formed under hydrogen peroxide are very stable and in particular when used later under the conditions of the primary circuit Nuclear power plant do not allow spinel formation.
- Parts that have surfaces to be treated can either be removed or treated separately.
- Systems, such as tanks, pipes, pumps, can also be treated when installed by coating them on their water-exposed inside.
- Another advantage of the treatment of steels with hydrogen peroxide is that the surface treatment of the steel can be checked visually by changing the color.
- the drive according to the invention treated surface from deep gold to dark blue-violet. Basically, all spectral colors result, depending on the layer thickness and the type of light reflection.
- the method according to the invention is also generally suitable for coloring stainless steel or nickel alloys, in that the cleaned surface e.g. is treated with peroxide under water.
- the coloring is not only interesting in connection with the specified uses of the process in nuclear technology, but also in non-nuclear areas.
- Such a layer thickness is e.g. achieved with a treatment time between 10h and 300h.
- Example 1 Open container (unpressurized) Temperature: ⁇ 100 ° C Pressure: atmospheric
- the present invention proposes a method for the surface treatment of steel, such as in particular stainless steel, as well as nickel alloys, for example of the type Incoloy 800, Inconel 600, and the like, as are used particularly in steam generators of pressurized water reactors, the treatment with Peroxide or a water per oxide mixture or solution takes place. It is important that a protective layer of oxide is formed on the treated surface.
- the surface can be the surface of a container, pipeline, pump, etc.
- the feed water preheaters could also be treated using the method mentioned here in order to reduce the introduction of corrosion products into the reactor.
- the advantage is achieved in particular that surface contamination can occur later or only with difficulty when operating a system.
