に耐える金めっき製品の製造は極めて困難である。2. Description of the Related Art Since ancient times, gold has been prized as a symbol of wealth due to its brilliant golden color and luster. Money, works of art, crafts,
It has been widely used in jewelry. Conventionally, daily necessities such as tableware such as spoons, forks, plates, etc. that are made of gold or plated with gold have been put into practical use, but due to the improvement of living standards these days, this tendency is becoming stronger and stronger.
For example, large-capacity items such as bathtubs, pots, and kettles, front doors,
There are great expectations for building materials such as elevator doors and interior and exterior materials for buildings and structures. However, in these bathtubs, pots, etc., after daily use, they are rubbed with scrubbing brushes, sponges, etc., exposed to chemicals such as detergents and bath additives, etc. ,
It is necessary to withstand extremely harsh conditions such as contact with other objects and exposure to wind, rain, salt, acid rain, etc., and it is extremely difficult to manufacture a gold-plated product that can withstand such conditions.

って腐食が起こるのである。First, on stainless steel that has not rusted in the past,
It is generally considered that if the gold plating that does not rust is applied, it will not rust forever, but in fact, the exact opposite is true. The reason is that stainless steel does not easily rust because there is a passivation film (oxide film) formed on its surface, but gold plating on stainless steel has an activity of removing this passivation film. Chemical treatment is essential. And since this passivation film is removed, pinholes are likely to occur especially when the plating thickness is thin,
A local battery is formed between the plating film and the stainless steel base, and even a stainless material that is resistant to rust causes corrosion due to the difference in ionization tendency.

ある。Second, it is very difficult to apply gold plating to a large size such as a bathtub or a building material with a uniform thickness.
There is also the problem that equipment costs are heavy. Since gold plating on these large-sized stainless steels has the above-mentioned troublesome problems, there is a large demand, and it is the actual situation that such demands cannot be met until today.

It has been found that the above problems can be solved all at once by carrying out the above, and the present invention has been completed.

成させたものである。The inventors of the present invention have found that the gold-plated stainless steel does not have the corrosion resistance because of the activation treatment for removing the passivation film, while the gold-plated stainless steel has the passivation treatment. The problem of the trade-off that the film must be removed is to use a stainless steel material on which a passivation film is grown and formed by a passivation treatment on the film without removing the passivation film. Further, they have found that it is possible to perform gold plating on the passivation film by using a hydrochloric acid acidic gold plating solution, and have completed the present invention.

い。The surface of the stainless steel is deactivated. For the deactivation treatment, for example, 15% nitric acid solution is mixed with about 40 g / L of ferrite (ferric tetroxide Fe 3 O 4 ) and stirred, and the resulting mixed solution is impregnated into a fiber mat-like material. Lapping by applying a certain pressure. In a preferred example, the above-mentioned mixed solution is impregnated into an acid-resistant synthetic fiber felt mat containing pure hair or a roll-shaped material made of the felt, and a pressure of about 1 kg / cm 2 is applied to the mixture to a rate of 200 to 40 min.
Rotate 0 and wrap. By this treatment, a new passivation film layer is formed on the surface of stainless steel by polishing the fine ferrite powder, and this layer has a temperature of about 1 due to heat of abrasion.
The temperature rises to 00 ° C. and the formation of the passivation film layer is accelerated. The concentration of nitric acid, the concentration of ferrite, the lapping pressure of the roll, the number of revolutions, etc. may be appropriately determined depending on the type of stainless steel used, the desired degree of formation of the passivation film, and the like. The passivation film layer of the present invention is preferably further grown and formed on the passivation film layer which is naturally formed on the surface of stainless steel. The passivation film layer may be provided.

できる。The feature of the present invention is that the conventional gold plating on stainless steel requires an activation treatment to remove the passivation film (passivation film), while the activation treatment must not be applied. For example, the problem of the trade-off that stainless steel corrodes and cannot be put to practical use lies in the fact that the passivation treatment is performed to actively grow and form the passivation film layer, and this is successfully used for gold plating. . By using a hydrochloric acid acidic gold plating solution, the stainless steel material of the present invention can be subjected to gold plating on the passivation film, which has been considered impossible.

た耐蝕性、耐摩耗性を有するのである。The reason why gold can be plated on the passivation film of the stainless steel material of the present invention is considered as follows. That is, when the stainless steel material of the present invention is immersed in the plating solution, the surface of the passivation film layer starts to dissolve immediately, but at the same time as this dissolution, electrodeposition starts. The passivation film layer dissolves to the extent that gold plating is applied, but since it is instantly gold-plated, the passivation film layer remains almost undissolved and remains on the passivation film layer. It is plated with gold. Thus, the obtained gold plating layer has excellent corrosion resistance and wear resistance.

は頗る大である。According to the present invention, large-capacity containers such as bathtubs, pots and kettles, as well as gold-plated products such as doors, interior materials, exterior materials, etc. can be provided, and the passivation film has been removed as in the prior art. Since gold plating is applied on the grown passivation film layer instead of gold plating on the surface, it is required for these functions such as corrosion resistance, abrasion resistance, chemical resistance, boiling water resistance, etc. It is possible to provide a gold-plated product that can sufficiently withstand the harsh conditions required. However, it goes without saying that the stainless steel material of the present invention has excellent corrosion resistance and wear resistance as compared with the conventional one because the passivation film layer is grown and formed even if it is used as it is. As described above, according to the present invention, an inexpensive and high-performance gold-plated product can be provided, and its usefulness is extremely large.
