Performance is being improved through surface treatments such as n-based alloy plating. Many types of Zn-based alloy plating have been proposed, such as Zn-Fe-based plating, Zn-Ni-based plating, and Zn-Mn-based plating. However, in order to meet all of the various performance requirements for automobile exterior panel materials as described below,
It is difficult to satisfy this problem with a single plating layer hot plate, and the current situation is to adopt a complicated structure such as two-layer plating. That is, Zn-Fe.

めっき構造が採用されている。Although Zn-based plating layers such as Zn-Ni can provide excellent corrosion resistance, they are actually worse than base steel sheets in terms of electrodeposition coating properties, spot weldability, etc. required for automobile exterior panel materials. To cope with this, a two-layer plating structure is adopted in which an Fe-based plating layer is further applied on the surface of the Zn alloy plating layer.

ング等が発生するという問題もありた。[Problems to be solved by the invention] However, in such a two-layer plating, since two layers with different potentials are laminated, a contact cell is formed between the two layers, resulting in poor corrosion resistance. There was a problem that it caused deterioration. Moreover, if the hardness of the two layers is significantly different, there is a problem that so-called bactering, flaking, etc., in which the plating layers peel off during processing such as press molding, occurs.

なった。[Function] The present inventors considered that the reason why the conventional two-layer plating causes the above-mentioned problems is due to the discontinuous layer structure. That is, 2
In the layered plating structure, as shown in Figure 2, the concentrations of each component of Fe and Zn in the plating layer are clearly reversed between the two layers.
It was thought that this would cause deterioration in corrosion resistance and poor workability. Therefore, the present inventors first attempted to create a plated layer whose composition changes continuously in the thickness direction of the plated layer.

ことが判明した。However, even if it were attempted to realize this using the wipe method, which has been widely used in the past, there were problems as shown below. For example, in the electroplating method, it is necessary to strictly control the plating bath composition and plating conditions, and it is extremely difficult to perform a process in which the concentration of each component in the plating layer is continuously changed. In addition, in a method using heat diffusion treatment after plating, as seen in alloyed hot-dip galvanized steel sheets, Fe and Z
A phase, which is an intermetallic compound, is formed by the diffusion of n.
It was found that the r-phase was brittle, which actually resulted in poor workability.

である。Therefore, as a result of further intensive research, the present inventors adopted a vacuum evaporation method and controlled the amount of evaporation of each by adjusting the heating temperature of Fe and Zn. It was revealed that Zn-Fe alloy plating can be formed. And Zn on the surface of the plating layer
If the Zn content is adjusted within a specific range and the Zn content in the plating layer is adjusted so that it gradually increases in the depth direction of the plating layer (see Figure 1), corrosion resistance and coating properties can be improved. The present invention was completed based on the discovery that a surface-treated steel sheet for automobiles can be obtained that exhibits excellent performance not only in terms of properties but also in workability. Furthermore, the surface-treated steel sheet obtained in this manner does not contain the r-phase in its plating layer.

おけるＺｎ含有量の好ましい範囲は１０〜３０重量％程
度である。As mentioned above, the plating layer in the surface-treated steel sheet according to the present invention has a structure in which the Zn content gradually increases from the surface of the plating layer to the depth direction of the plating layer, as shown in FIG. The Zn content at least on the surface of the plating layer needs to be 5 to 40% by weight. If the Zn content exceeds 40% by weight, paintability and weldability will deteriorate, and if it is less than 5% by weight, corrosion resistance will deteriorate. The preferred range of Zn content on the surface of the plating layer is about 10 to 30% by weight.
一方めっき層内部におけるＺｎ含有量は特に限定するも

都合は生じない。On the other hand, the Zn content inside the plating layer is not particularly limited, but considering corrosion resistance, it is 60 to 90! i amount%
The amount is preferably about 75 to 90% by weight. However, even if the Zn content of the plating layer at the interface with the surface steel sheet becomes 100% by weight, no problem occurs because the adhesion between the vapor-deposited plating layer and the base steel sheet is very good.

装入する。In manufacturing the surface-treated steel sheet according to the present invention, for example, the process is carried out as shown in Figure 'rJ3 (schematic explanatory diagram). 2 crucibles 2a along the running direction of 1
, 2b are arranged, and Z is arranged in the crucible 2a on the upstream side in the traveling direction.
At the same time, Fe is charged into the crucible 2b on the downstream side.

れる。Zn and Fe are then heated and evaporated, respectively, and vapor deposition is performed while wrapping each vapor atmosphere in the longitudinal direction of the steel plate 1 as shown in the figure. Then, a mixed vapor with a high Zn vapor ratio is first vapor deposited on the steel plate 1, A mixed vapor having a gradually decreasing Zn vapor ratio is sequentially deposited thereon, and a mixed vapor having the highest Fe vapor ratio is deposited on the most downstream side in the running direction.

とができる。As a result, a plating layer with the lowest Zn content is formed at the outermost layer, and a Zn--Fe alloy plating layer 3 whose Zn content gradually increases toward the lower layer is formed. Then, by adjusting the heating conditions of each crucible 2a, 2b and the degree of vacuum in the vacuum device, the Z constituting the plating layer 3 can be adjusted.
The Zn content of the n-Fe alloy can be freely controlled, and the plating thickness can be arbitrarily adjusted by changing the running speed of the steel plate 1 and the amount of evaporation of Zn and Fe.

It is not limited to this range. Therefore, in the outermost layer of the plating layer (i.e., the most downstream side of the steel plate 1), Fe is 1
00% by weight of Fe, and as described above, a plating layer with the smallest Zn content within the range of 5 to 40% by weight will be formed. The method of heating the crucibles 2a and 2b is not limited in any way, and resistance heating, high frequency heating, high energy beam heating using an electron beam, laser, etc. can also be employed.
