That is, according to the present embodiment, it is not necessary to use a chemical product that causes an environmental load such as a chromate treatment solution containing hexavalent chromium. For this reason, it can also contribute to environmental protection.
- a molten aluminum melt is filled into a mold, and the shape of the throttle body 10 is made into a forged caroe. To do.
- the molten metal is solidified in the mold to become a forged molded product. Then, after a predetermined time has elapsed, mold opening is performed, and the forged molded product is released. The forged molded product is then left for a predetermined time in an air atmosphere, where solidification proceeds to the inside.
- shot blasting is performed on the forged molded product. That is, a spherical blast material is projected toward a forged molded product, as is generally done in deburring and paint removal.
- a material having an aluminum strength with a purity of 98% or more is selected. If the purity is less than 98%, it is difficult to obtain good corrosion resistance even if the corrosion-resistant film 16 is formed. It is more preferable to select one having a purity of 99% or more.
- the particle size of the blast material is not particularly limited, but may be between 0.7 and 0.9 mm, for example, approximately 0.8 mm.
- the projection speed and projection time of the blast material are not particularly limited, but if the projection speed is set between 60 and 70 mZ seconds, for example, approximately 66 mZ seconds, the projection time can be set to approximately 1 minute. Good.
- the projected blast material collides with the passive film 14. With this collision, a recess 18 is formed in the passive film 14. In addition, the blast material peeled material remains and adheres to the recess 18, thereby forming a metal layer 20 having a shape substantially corresponding to the shape of the recess 18.
- this metal layer 20 is made of aluminum which is the material of the blast material.
- the formation of the metal layer 20 can be confirmed, for example, by X-ray photoelectron spectroscopy (XPS).

Specifically, hot water washing, degreasing, water washing, activation, water washing, hot water washing, etc. are sequentially performed.
- a corrosion resistant film 16 is provided on the passive film 14.
- trivalent The forged molded product is immersed in a chromate treatment solution containing chromium. By this immersion, a chromate film containing trivalent chromium grows, and as a result, a corrosion-resistant film 16 containing trivalent chromium is formed.
- chromate treatment solution is ALT610 (trade name of a treatment solution manufactured by Dipsol Corporation).
- the corrosion-resistant film 16 is not sufficiently formed, and it is difficult to obtain sufficient corrosion resistance. Therefore, the reason why the corrosion-resistant film 16 is sufficiently formed by shot blasting is that the chromate film can be easily formed due to the presence of the high-purity aluminum metal layer 20. Inferred.
