Description of the Related Art In recent years, from the viewpoint of preventing air pollution, there has been a call for improvement in fuel efficiency of automobiles, and as part of this, weight reduction of vehicle bodies has been promoted. In order to reduce the weight of a vehicle body, the thickness of a steel material to be used has been reduced by increasing the tensile strength of a steel material, but recently, the use of an aluminum alloy plate has been drawing attention. As this alloy plate, JIS 5000 series (Al-
Mg-Cu system) and JIS6000 system (Al-Mg-Si)
Primarily used for wrought materials such as lacquer, but the used parts are limited to parts such as hood, trunk lid, front and rear fenders.

アルミニウム合金板にもリン酸塩処理性が要求される。The production of automobiles using steel materials is normally carried out in the order of degreasing, phosphate treatment, cationic electrodeposition undercoating, intermediate coating and topcoating after assembling the parts into a vehicle body. However, even when a part of the aluminum alloy plate is used, it is manufactured in this process. Therefore,
The aluminum alloy plate is also required to have phosphatability.

In combination with the composition of the aluminum alloy plate, significant blistering corrosion or filiform corrosion may occur under the coating film after painting.

ことのできるものではなかった。Therefore, in order to prevent the occurrence of such corrosion,
Only aluminum alloy plate parts may be pre-treated with a chromate-based paint prior to being incorporated into the vehicle body.If phosphate treatment is used, a large amount of etching agent such as fluoride should be added to the phosphate treatment solution. Therefore, some methods have been attempted to increase the reactivity with the aluminum alloy plate.
However, the former method has a problem that the work is complicated and harmful chromium is mixed in the treatment liquid during the phosphate treatment of the vehicle body. Even in the latter method, all of them cannot be satisfied because steel parts also use materials having different phosphating properties such as cold-rolled steel sheets and zinc-based surface-treated steel sheets.

That is, the present invention improves the phosphating property and the corrosion resistance after coating by applying Al-Zn alloy plating to an aluminum alloy plate, and the Zn content is 3.0 to 50 m on at least one side of the aluminum alloy plate.
It is characterized in that the Al-Zn alloy plating of ass% is applied to 0.2 to 10 g / m 2 .

発明では、上記のように、Ａｌ−Ｚｎ合金をめっきした
のである。In order to improve the etching property of the aluminum alloy plate, there are a method of incorporating zinc having high reactivity with a phosphate treatment solution into the aluminum alloy plate, a method of coating the surface of the aluminum alloy plate with zinc, and the like. In the case of the former method, it was found that zinc tends to segregate at the α-Al crystal grain boundaries, so that fine and dense phosphate crystals do not precipitate. On the other hand, according to the latter method, uniform and dense crystals are deposited, but since a zinc coating layer having poorer corrosion resistance than Al exists between the phosphate layer and the base aluminum alloy plate, it is applied after electrodeposition coating. Sub-film corrosion is likely to occur,
It turned out to be very unstable in practice. Therefore, in the present invention, the Al—Zn alloy is plated as described above.

5052, O material, plate thickness 1.0 mm) is a graph showing the phosphate treatment property and the corrosion resistance after electrodeposition coating (the size of the coating film bulge width from the cross-cut portion). It can be seen that the phosphate treatability becomes good when the Zn content is 3 mass% or more. If the Zn content is less than 3 mass%,
The fact that uniform phosphate crystals do not precipitate is due to the small amount of Zn that has good reactivity with the phosphate treatment liquid.

で、好ましくは５.０〜３０mass％であるといえる。On the other hand, if the Zn content exceeds 50 mass%,
Corrosion resistance after electrodeposition coating is drastically reduced.
This is because the Al-Zn alloy plating layer having a high Zn content is present below the phosphate layer, and this layer is selectively corroded. Therefore, it can be said that the Al-Zn alloy plating needs to have a Zn content of 3.0 to 50 mass%, and preferably 5.0 to 30 mass%.

ある。In order to improve the phosphating property of the aluminum alloy plate by Al-Zn alloy plating, it is necessary to set the coating weight to 0.2 g / m 2 or more. If the amount is less than 0.2 g / m 2 , the surface cannot be completely covered, resulting in non-uniform phosphate crystals. On the other hand, although the phosphate treatment property does not change even if the coating amount is increased, it is economically disadvantageous to increase the amount too much, so 10 g / m 2 at most is sufficient.

It is preferable that Zn is microscopically uniformly dispersed in Al. Such Al-Zn alloy plating can be performed by an electroplating method using a room temperature molten salt bath, for example, a molten salt bath composed of aluminum chloride and organic nitrogen-containing onium chloride or a bath containing zinc chloride added thereto. Is. Further, vacuum plating such as electron beam heating type vapor deposition plating using a pure Al bath and a pure Zn bath juxtaposition method, ion plating, or ion sputtering may be performed. According to these plating methods, Al-Zn alloy plating in which Zn is uniformly dispersed in the plating layer can be applied as compared with the case of hot-dip plating.
