The steel plate referred to here is a plain steel plate, a high-strength steel plate, a Zn-based electroplated steel plate, or a Zn-based hot dip plated steel plate. Of these, surface-treated steel sheets such as Zn-plated steel sheets are excellent in corrosion resistance, and are therefore widely used in areas where corrosion is likely to occur, such as fenders and door panels. On the other hand, recently, there has been a demand for using an aluminum plate for a body of an automobile, mainly for the purpose of reducing the vehicle body weight for improving the fuel efficiency and power performance of the automobile. However, it is rare at present to manufacture an entire body of an automobile from an aluminum plate, and in general, a part of the body is replaced with a steel plate from an aluminum plate. Therefore, an automobile body is assembled by using a steel plate and an aluminum plate together.

ての燐酸亜鉛処理性に関していくつかなされている。In an automobile body assembly / manufacturing line, a body steel plate and an aluminum plate are formed into a predetermined shape by pressing or the like, and then these members are spot-welded by resistance welding to be assembled into a body. Most of the body assembly process by resistance welding is currently performed by an automatic assembly robot, and it is desired to assemble the above-mentioned member made of a steel plate and an aluminum plate under welding conditions of a member made of only a steel plate. . By doing so, it is not necessary to change the welding conditions each time depending on the welding site even when using a steel plate and an aluminum plate together,
Since the process continuity is maintained, it is advantageous in terms of manufacturing cost. Some attempts have been made to make the properties of an aluminum plate required for assembling an automobile body close to those of a steel plate with respect to zinc phosphate treatment as a pretreatment for coating.

Japanese Patent No. 7680 proposes a method of applying a Zn plating layer to an aluminum plate as a method of improving the zinc phosphate treatment property of the aluminum plate. On the other hand, there is little related to resistance weldability, and there is a method of improving continuous spotting property at the time of resistance welding by a plating treatment method comprising two layers of a Ni plating layer and a Zn-based alloy plating layer, which is found in JP-A-3-146693. Proposed. However, a surface treatment method that is simpler and has excellent resistance weldability is desired from the viewpoint of the complexity of the process by the two-layer plating treatment and the manufacturing cost. Therefore, as in the present invention, there is no one in which the resistance weldability of the Al alloy plate is remarkably improved by the Zn-Fe alloy plating layer in which the composition of the plating layer and the amount of the deposited coating are defined.

However, the aluminum plate has a drawback that the welding current value becomes too large as compared with the steel plate. The reason for this is currently unknown. Probably, it is speculated that aluminum has a lower melting point than steel and has a good thermal conductivity, so it easily melts, so the electrical conductivity becomes too high and the area of the fused part becomes too large at the same time. . Further, in the case of an aluminum plate, it has a drawback that the wear of the welding electrode is severe and the continuous dot-forming property is significantly inferior to that of the cold-rolled steel plate. Accordingly, the present invention provides an aluminum plate that solves the above problems, that is, an aluminum plate having excellent resistance weldability such that the welding current value and the continuous spotting property are equal to or close to those of the steel plate.

The Zn-Fe based alloy plating layer covers the surface of aluminum to suppress the formation of an insulative passive film of aluminum. Further, the welding current value is set to an appropriate value by suppressing an excessive increase in electric conductivity due to melting of aluminum during resistance welding. The reason for its action is unknown, but Zn-F
It is considered that the melting point, electrical conductivity, and thermal conductivity of the e-based alloy plating layer affect the temperature. That is, Z of the binary alloy
The n-Fe alloy becomes ζ, δ, and Γ phases in the order of increasing Fe content in the range of 5 to 60 wt% Fe content. All of these alloys have a higher melting point than pure zinc and have a melting point of Al or higher.
Moreover, since the electrical conductivity and the thermal conductivity are smaller than that of aluminum, the optimum welding current value during resistance welding becomes small due to the physical properties of these Zn-Fe alloy layers, which is close to that of cold-rolled steel sheet. It is considered that the current value was reached.

To 60% by weight, it was found to be good. Fe content less than 5% by weight or 60% by weight
If the value is larger, the welding current value is significantly different from the value of the cold-rolled steel sheet, which is not suitable. The coating weight is 6 g /
When the value is smaller than m 2, the thickness is too thin as compared with the thickness of an aluminum plate that is usually used as a vehicle body outer plate, and there is no effect.

The wear of the electrode during resistance welding was negligible, improving the so-called continuous spotting property.

However, it is possible to obtain a film equivalent to the chemical conversion film formed on a cold rolled steel plate, or to lubricate the plate. Fe-Zn containing 5 to 20% by weight of Fe plating layer or Zn for the purpose of improving the property
Even if the alloy plating layer is applied in an amount of about 1 to 5 g / m 2, it does not hinder the action of the Zn—Fe based alloy layer of the material of the present invention as the lower layer, and there is no problem.

的に説明する。The present invention may be produced by a known plating method, and can be produced, for example, by a method in which various vapor deposition methods are combined, but it is usually produced by an electrolytic method. However, since aluminum generally has a markedly poor adhesion to plating, it is common to perform a base plating treatment. As a known undercoating treatment, a zincate method, an anodizing method, and a hot dipping method are known. Here, the zincate method is a displacement plating method using an alkali zinc bath, the anodizing method is a method of forming an anodic oxide film of aluminum and then plating, and the hot dipping method is electrolytic plating treatment followed by heat treatment. A method of forming an alloy diffusion layer on the plating interface. The former two methods both form a very small amount of the underlayer at the plating interface and do not affect the action of the Zn—Fe alloy plating layer of the present invention. Further, even in the hot dipping method, there is no structural change that affects the operation of the present invention. As an electrolysis method, for example, after zincate treatment, zinc sulfate, iron sulfate and Ni,
Zn is obtained by cathodic electrolysis at a current density of 5 to 200 A / dm 2 using Pb as an anode and an aluminum plate as a cathode in an aqueous solution containing one or more sulfates of Co, Cr, Mn, Sn and Cu. -Fe-based alloy plating is obtained. Hereinafter, the effects of the present invention will be described more specifically with reference to Examples.
