A material made of a highly corrosion-resistant material such as 385 was used. However, rivets made of these materials have low strength (proof strength) and can only be driven into thin plates. To drive into thick plates, rivets with large diameters that are unbalanced with the plate thickness are required. In this case, there is a problem that the driven plate is greatly distorted. Therefore, in order to improve the strength of the rivet, a material such as SUS410 or SUS420 may be subjected to heat treatment before use, but in this case, there is a problem that the rivet is easily rusted. Of course, it is possible to perform plating to improve the corrosion resistance,
At the time of the driving, the plating is easily peeled, and there is a possibility that the plating may be peeled off during use. In this case, there is a problem that rust is generated from the portion where the plating has been peeled.

As a method of the passivation treatment, a method of dipping the rivet after barrel polishing in a concentrated nitric acid solution for about several minutes can be exemplified, but it is not particularly limited to this method. Since the driving rivet according to the present invention forms an oxide film on the surface by performing the passivation treatment as described above, it has extremely excellent corrosion resistance without performing plating treatment as in a conventional rivet. Become. Therefore, there is no danger of hydrogen embrittlement, and the plating cost can be reduced.
