面から自動車用鋼板として好適な合金化亜鉛めっき鋼板
に係るものである。[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to an alloyed galvanized steel sheet with excellent workability, and is particularly suitable as a steel sheet for automobiles from the viewpoint of improving powdering resistance during processing. This relates to a suitable alloyed galvanized steel sheet.

錆鋼板化が急速に行われつつある。Generally, the performance required for automotive steel sheets includes corrosion resistance after painting, weldability, workability, etc., but in North America, Canada, and Northern Europe, large amounts of rock salt have traditionally been sprayed to prevent roads from freezing in winter. In such an environment, corrosion of automobile bodies is accelerated, and corrosion prevention measures workers have to study hard, but as a means of solving this problem, the use of rust-proof steel plates for automobiles is rapidly being carried out. It's coming.
このような目的に合致する防錆鋼板としては、たとえば

れている。As a rust-preventing steel sheet that meets this purpose, for example, an alloyed galvanized steel sheet as seen in Japanese Patent Publication No. 57-14752 is known, and such steel sheets have excellent corrosion resistance after painting, weldability, etc. Because it has excellent properties and can be made thicker, it is used in large quantities as a steel sheet for automobiles.

方法は特に限定されるものではない。In addition, the alloyed galvanized steel sheet referred to here refers to a copper plate or copper strip that is coated with zinc plating with a predetermined coating weight on one or both sides, and then subjected to post-mortem 1-alloying heat treatment to transform the plating layer into a Zn-Fe alloy. This is what I did. in this case,
The components of the base steel sheet, the method of galvanizing, the At degree in the bath in the case of hot-dip galvanizing, the amount of zinc coating, and the method of alloying treatment are not particularly limited.

がある。However, when the above-mentioned alloyed galvanized steel sheets are subjected to severe processing, the plating layer may collapse and flake off into powder, a product defect called powdering, which causes problems with corrosion resistance after processing. At the same time, fragments of the peeled-off plating layer may accumulate on the press mold, causing problems such as indentation scratches on the molded product.

に生ずると考えられる。The cause of such powdering in alloyed galvanized steel sheets has not been elucidated by optical spectroscopy, but
The brittle nature of the plating layer is thought to be due to the inability of the plating layer to follow the plastic deformation of the underlying steel sheet during processing.
従ってこれまでにめっき層の加工性を改善するために種
々の検討がなされてきた。Therefore, various studies have been made to improve the workability of the plating layer.
例えば特公昭４９−４１３４号公報にみられるように、
亜鉛めっき層を合金化する際の加熱条件を適当に選択す

する手段などがある。For example, as seen in Japanese Patent Publication No. 49-4134,
By appropriately selecting the heating conditions when alloying the galvanized layer, the outermost surface of the alloyed galvanized layer becomes (η+
ζ) There are means to improve the workability of the plating layer by creating a mixed phase.
これらの対策によって合金化亜鉛めっき銅板の耐パウダ

ダリングが発生することがあり、改善の余地が残されて
いる。Although these countermeasures have gradually improved the powder-linder resistance of alloyed galvanized copper sheets, powdering still occurs in some cases, and there is still room for improvement.

塗装後耐食性、溶接性等を劣化させることなく・ぐラダ
リングの発生を抑制できることを見出した。In view of the above-mentioned situation, the inventors of the present invention have carried out numerous experiments and have found that the upper layer of the plating layer of the 1-alloyed galvanized steel sheet is an electrolytic galvanized layer or an electrolytic Zn-N layer having an appropriate basis weight.
By forming any of the I alloy plating layers,
It has been found that the occurrence of sloppy ring can be suppressed without deteriorating corrosion resistance, weldability, etc. after painting.
この理由は明らかではないが、恐らく合金化亜鉛めっき
鋼板のめっき層上層に形成された電気亜鉛めっき層、も
しくは電気Ｚｎ−Ｎｉ合金めっき層が。The reason for this is not clear, but it is probably due to the electrolytic galvanizing layer or electrolytic Zn-Ni alloy plating layer formed on the plating layer of the alloyed galvanized steel sheet.

抑制するものと考えられる。This is probably because it has good adhesion with the lower layer and has moderate ductility. In other words, even if the lower Zn-Fe alloy plating layer is processed under processing conditions that cause powdering, the upper zinc plating layer or Zn-N'i plating layer can closely follow the plastic deformation of the underlying steel sheet, so the lower layer It is thought that this suppresses the peeling and falling off.

。The present invention has been made based on the above findings, and the gist thereof is to provide an upper layer of a plating layer of a single-sided or double-sided alloyed galvanized steel sheet with an area weight of 3 to 25 per side.
Electrogalvanized layer of fg/m2 or area weight 3
The present invention provides an alloyed galvanized steel sheet with excellent workability, characterized by having an electrolytic Zn-Ni alloy plated layer with a Ni content of 30 wtl or less and a Ni content of 30 wtl or less.
以下本発明の詳細な説明する。 。The present invention will be explained in detail below. .

かも適度な延性を有するととか。First, the reason why the upper layer plating is limited to zinc or Zn-N1 alloy will be described. That is, in order to improve the powder-linder resistance of the above-mentioned through-alloyed galvanized steel sheet, the upper layer of the plating layer must have good adhesion to the lower layer and have appropriate ductility.

'+ We investigated button powdering properties during processing of steel plates, and investigated the corrosion resistance and weldability after painting for those for which an improvement effect was observed. The results are shown in Table 1.

It was confirmed that the i-series can improve the powdering resistance without deteriorating the above-mentioned good performance of the alloyed galvanized steel sheet.

再び耐・母つダリング性が悪くなるためである。These plating layers have good adhesion with the plating layer of the alloyed galvanized steel sheet, and in the case of electrogalvanizing, they are composed of η-phase monotony, and in the case of electrolytic Zn-Ni alloy plating, they are composed of η-phase ( Zinc solid solution containing Nl) single phase or η
It is composed of two phases: phase and γ phase (Zn2.Ni5), and also has appropriate ductility. In this case, the basis weight for electrogalvanizing was limited to 3 to 251/m2 because
The powdering suppression effect of the electrogalvanized layer has a basis weight of 3.
Recognized at fg/m2 or higher, 25? This is because if it exceeds /m2, the resistance to mating will deteriorate again.

効果が認められなくなるためである。In addition, the basis weight of electric Zn-Ni alloy plating is 3 to 151.
The reason why it is limited to 7 m'' is because, as in the case of zinc plating, the powdering suppressing effect is observed at a basis weight it 3 ii'/m'' or more, and if it exceeds 15917 m'', the powdering resistance deteriorates again. Furthermore, the Ni content of electrolytic Zn-Ni alloy plating was limited to 30 wtl or less because if the Ni content exceeds 307 t%, the alloy plating layer becomes brittle due to being dominated by the γ phase, and the powdering suppressing effect is no longer observed. It's for a reason.
