に少ない。 (Industrial Field of Application) The present invention relates to a toughened steel sheet that provides an excellent paint finish when used for coating components, such as cationic electrodeposition coating, such as automobile bodies. (Prior Art) Rock salt is sprayed on roads in North America, Canada, and Northern Europe in winter to prevent freezing, so steel plates used in automobile body parts are required to have excellent anticorrosion performance. For this reason, Zn-based alloy plated steel sheets, which are coated with a single layer of Zn-based alloys such as Zn-Fe-based alloys and Zn-Ni-based alloys, which have excellent corrosion resistance, have recently come to be used in such applications. . However, if these Zn-based alloy plated steel sheets are single-layer plated, when cationic electrodeposition coating is applied after phosphate treatment, craters will occur in the coating film, resulting in poor coating finish. It was hot. Therefore, in order to improve the problem of paint finish, we developed a plated steel sheet that has an Fe content of 60 to 60, which has good electrodeposition paintability, in addition to the alloy plating mentioned above.
A multilayer plated steel sheet with a high Fe-Zn alloy plating of less than 100wt% has been proposed. It is true that if the steel plate is multi-layered, the occurrence of craters in the coating film due to cationic electrodeposition coating will be reduced compared to single-layer plating, and the finish quality of the coating will be improved. However, conventional multilayer plated steel sheets have high Fe-
In order to reduce the occurrence of coating film craters by Zn alloy plating, the amount of plating applied must be 5 g/m 2 or more per side, resulting in a problem of high manufacturing costs. (Problems to be Solved by the Invention) The present invention provides high Fe-
In multi-layer plated steel sheets with Zn alloy plating,
The present invention provides a plated steel plate for painting that is inexpensive to manufacture. (Means for Solving the Problems) The present inventors have developed Zn-based alloy plating and high Fe-Zn
In order to develop an inexpensive multi-layer plated steel sheet with alloy plating as the lower and upper layers, we conducted various studies and found that if the upper layer contains B (boron), the plating thickness of the upper layer can be reduced. We have found that it is possible to reduce the Fe content in the upper layer. In other words, the present invention adds B to the conventional high Fe-Zn alloy plating of the upper layer, thereby thinning the upper layer.
This is intended to improve paintability and reduce the difference in corrosion potential between the upper and lower layers by reducing the Fe content.The lower layer is plated with a Zn-based alloy, and the upper layer is coated with 0.001wt of B.
% or more, and is characterized by high Fe-Zn alloy plating with an Fe content of 50 to less than 100 wt%. The plated steel sheet of the present invention cannot reduce the occurrence of paint film craters unless the coating weight of the upper layer of high Fe-Zn alloy is 5 g/m 2 or more in conventional multi-layer plated steel sheets. Therefore, even if the amount is as low as 0.2 g/m 2 , the occurrence of coating film craters can be reduced compared to conventional multi-layer plated steel sheets. The reason for this is not clear, but when B is added to the plating bath when electroplating the upper layer, the uniform electrodeposition of plating is improved, and when B is contained in the upper layer, the electrodeposition is improved. As a result of B improving the phosphate treatment properties in the phosphate treatment, which is a pre-painting treatment, a dense phosphate film is formed, and the electrical conductivity of the entire steel plate surface becomes uniform, making it easier for the paint to pass during electrodeposition coating. It is presumed that this is because the electrodeposition is uniform and the generation of craters is suppressed. In addition, the Fe content of the upper layer high Fe-Zn alloy plating had to be reduced to less than 60 to 100 wt% to reduce cratering, but even if it was reduced to less than 50 to 100 wt% by adding B. , can reduce cratering. The reason for this is presumed to be the above-mentioned effect of B on improving phosphating properties, but if the Fe content can be reduced in this way, the difference in corrosion potential between the upper layer and the lower layer becomes smaller, which improves plating. The long-term corrosion resistance of the entire layer can be improved. Incidentally, the amount of B contained in the high Fe-Zn plating of the upper layer is preferably 0.001 to 3 wt%. This is because when the B amount is less than 0.001 wt%, crater generation during electrodeposition coating is the same as when high Fe-Zn plating does not contain B, and even when the B amount exceeds 3 wt%, the effect is saturated. This is because there is no point in increasing the content more than 3wt%. 0.001~3wt% of B during high Fe-Zn plating of the upper layer
To contain boric acid, metaboric acid, soluble metaboric acid, soluble 4 in a normal Fe-Zn alloy plating bath.
Plating may be carried out by adding one or more boron compounds such as borates and tetrafluoroborates to adjust the pH of the bath to 1.5 to 3.0. The amount of plating on the upper layer is preferably 0.2 to 8 g/m 2 . If it is less than 0.2 g/m 2 , it will not be possible to completely cover the underlying Zn-based alloy plating, and craters will appear due to the exposure of the lower layer; if it exceeds 8 g/m 2 , craters will appear. This is because the suppressing effect has been saturated and there is no need to increase the amount more than 8 g/m 2 . In addition, the saturation of this crater suppression effect is 10g/1 in the case of conventional high Fe-Zn alloy plating.
m 2 , and in this respect as well, the effect of reducing the amount of plating due to the addition of B is recognized. The present invention improves the manufacturing cost and quality of plated steel sheets whose lower layer is Zn-based alloy plating.
For Zn-Fe alloys, Ni (for Zn-Fe alloys), Fe (for Zn-Ni alloys), Co,
It can be improved even if it contains trace amounts of one or more of elements such as Cr, Mn, Mo, and Ti. In addition, improvements can be made to Zn-based alloys even if they are plated directly onto steel sheets by electroplating, vapor deposition, or hot-dip plating, or if they are alloyed by thermal diffusion after plating. be. Next, the present invention will be explained with reference to Examples. (Example) After a cold-rolled steel plate with a thickness of 0.8 mm was subjected to normal degreasing and pickling treatment to clean the surface, the lower layer of Zn-Ni or Zn-Fe alloy was first coated under the conditions shown in Table 1. Then, a top layer of B-containing high Fe--Zn alloy was applied thereon. Thereafter, the plated steel sheet and the conventional multi-layer plated steel sheet with upper layer Fe-Zn alloy plating were treated with a commercially available phosphating solution (Bt3030, manufactured by Nippon Parker), and then cationic electrodeposition was performed. The number of craters generated on the paint film after baking and drying was investigated. For electrodeposition, Elekron #9000 (manufactured by Kansai Paint Co., Ltd.) was used as the paint, and the coating was electrodeposited to a thickness of 23 μm at 300 V using the flash method, and baked and dried at 180° C. for 20 minutes. Table 2 shows the results of visual observation of the number of craters generated per unit area of the electrodeposition coating film. As is clear from Table 2, the upper layer contains B and high Fe.
- The galvanized steel sheet of the present invention, which has been subjected to Zn alloy plating, has a significantly lower number of craters even if the coating weight and Fe content of the upper layer are lower than those of conventional multilayer galvanized steel sheets.
