が使用されている。[Conventional technology] Cold-rolled steel sheets have been widely used for exterior panels of automobiles and home appliances, but recently the requirements for rust prevention have become even higher, and in order to meet these demands, the rust prevention effect has been improved. Steel plates coated with various types of plating with higher levels of corrosion resistance, as well as steel plates coated with paint, are used.

る。By the way, Zn electroplated steel sheets have been most commonly used as plated steel sheets with excellent rust prevention effects, but this is still not sufficient. Therefore, increasing the amount of plating may be the easiest way to obtain higher corrosion resistance, but increasing the amount of plating may cause deterioration in powdering properties during press forming, spot weldability, etc., and increase the cost of plating. Problems such as the rise in Therefore, it is desirable that the amount of plating deposited is as small as possible.
Zn alloy plating is being considered as another means to improve corrosion resistance. For example, Zn-alloy electroplating

しかしながら前記した様なＺｎ合金電気めっきを施した

本発明者らは高耐食性を有するＺｎ系めっき材料を得る

検討したところＺｎ−Ｍｇ合金蒸着めっきをしたものは

Ｚｎ合金蒸着めっきを施したものは塗装後耐食性にも優
れているという知見を得た。[Function] In order to obtain a Zn-based plating material with high corrosion resistance, the present inventors conducted various studies on the coating composition and plating method, and found that the material coated with Zn-Mg alloy vapor deposition has excellent bare corrosion resistance. It has been found that those coated with Zn vapor deposition plating or Zn alloy vapor deposition plating have excellent post-painting corrosion resistance.
次に上記知見を得るに至フた経過について述べる。Next, I will describe the process that led to the above knowledge.
まずめっき方法としては後に詳述する様に蒸着めっきが
優れている。しかしＺｎ−Ｍｇ合金の単層蒸着めっきで
は、裸耐食性は良くなるにもかかわらずＭｇ添加量が増
えるにつれて塗装後塗膜に傷等ができたときに偏部周辺
から塗膜ふくれ等が生じ易くなり、塗装耐食性に難点が
あることがわかった。First, as a plating method, vapor deposition plating is superior as will be detailed later. However, with single-layer vapor deposition plating of Zn-Mg alloy, although the bare corrosion resistance is improved, as the amount of Mg added increases, when the paint film is scratched after painting, blistering of the paint film tends to occur from around uneven parts. It was found that there was a problem with paint corrosion resistance.
この理由は、たとえば塗膜にクロスカット等の傷付けを
おこなって腐食環境下に曝した場合、偏部がアノードと
なる一方、偏部周辺の塗膜下はカソードになり、カソー

カリ性に劣るめっき層では腐食が発生・進行することに
なる為であると考えられる。即ちＺｎ−Ｍｇ合金蒸着め
っきにおいてＭｇの添加量が増すにつれて塗装後耐食性
が劣ってくるのは、Ｍｇの増加によって耐アルカリ性が
劣ってくるためである。The reason for this is that, for example, if the paint film is damaged by cross-cutting or the like and exposed to a corrosive environment, the uneven part becomes an anode, while the area under the paint film around the uneven part becomes a cathode, and the cathode part becomes 02◆ This is thought to be because the reaction of H, O+2e-→20H- makes the coating highly alkaline with a pH of 10 to 12, which causes corrosion to occur and progress in a plating layer with poor alkali resistance. That is, in Zn--Mg alloy vapor deposition plating, as the amount of Mg added increases, the corrosion resistance after coating deteriorates because the alkali resistance deteriorates as the amount of Mg increases.
そこでめっき層を耐アルカリ性に優れたものにすればカ
ソード部における前述の反応が進行しても塗装後耐食性
・耐塗膜剥離性が悪化することはない。Therefore, if the plating layer is made to have excellent alkali resistance, the corrosion resistance and peeling resistance after coating will not deteriorate even if the above-mentioned reaction at the cathode progresses.
上記観点から塗装後耐食性の優れたＺｎ系めっき材料を
得る目的でさらに検討した結果、Ｚｎ−Ｍｇ合金蒸着め
っき層の上にＺｎ蒸着めっき層あるいはＮｉ、Ｃｏ、Ｍ
ｎ、Ｆｅ、Ｃｒ、Ｍｏ。As a result of further investigation with the aim of obtaining a Zn-based plating material with excellent corrosion resistance after painting from the above viewpoint, we found that a Zn vapor-deposited plating layer or Ni, Co, M
n, Fe, Cr, Mo.
Ｃｕよりなる群から選ばれた１ｆｆｆｉ以上を含むＺｎ
合金蒸着めっき層で被覆したものは、前述の意味におい
て耐アルカリ性を発揮するので塗装後耐食性にも優れて
いるという結論に達した。Zn containing 1fffi or more selected from the group consisting of Cu
It was concluded that those coated with a vapor-deposited alloy plating layer exhibit alkali resistance in the sense mentioned above, and therefore also have excellent corrosion resistance after painting.
この際下層Ｚｎ−Ｍｇ合金蒸着めっき層におけるＭｇ含
有量は０．５％以上になると裸耐食性および塗装後耐食
性が特に優れたものとなり、０．５％未溝および４０％
を超えたものは裸耐食性や塗装後耐食性が低下する。At this time, when the Mg content in the lower Zn-Mg alloy vapor-deposited plating layer is 0.5% or more, the bare corrosion resistance and post-painting corrosion resistance are particularly excellent.
If it exceeds this value, the bare corrosion resistance and the corrosion resistance after painting will decrease.
また上層の蒸着めりき層はＺｎ単独層でも塗装後耐食性
が改善されるが、Ｎｉ、Ｃｏ、Ｍｎ。In addition, even if the upper vapor-deposited plated layer is a single Zn layer, the corrosion resistance after coating is improved, but Ni, Co, and Mn.
Ｆｅ、Ｃｒ、Ｍｏ、Ｃｕの合金化元素を１種以上含有す

記合金化元素の添加量は少量でもその効果を発揮するの
で下限値は定めなかったが、特に０．５％以上の添加に
よって添加に見合った効果が出はじめ、２０％でその効
果が飽和に達する。The improvement effect is even higher in those coated with Zn alloy vapor deposition plating containing one or more alloying elements of Fe, Cr, Mo, and Cu. Furthermore, addition of these alloying elements not only improves alkali resistance but also improves phosphate treatment properties. We did not set a lower limit for the above-mentioned alloying elements because they exhibit their effects even in small amounts; however, when they are added at 0.5% or more, they begin to produce effects commensurate with the addition, and at 20%, the effects reach saturation. reach

ｎ蒸着めっき層あるいはＺｎ合金蒸着めっき層の厚さが
０．１μｍ未満では下層Ｚｎ−Ｍｇ蒸着めっき層に対す
る被覆が不完全でめっきピンホール等の為、さほどの効
果が得られない。The thickness of each vapor-deposited plating layer is not limited, but especially the upper layer Z
If the thickness of the n-evaporated plating layer or the Zn alloy vapor-deposited plating layer is less than 0.1 μm, the lower layer Zn--Mg vapor-deposited plating layer is incompletely covered, resulting in plating pinholes, etc., and no significant effect can be obtained.
これに対し０．１μｍ以上であれば防食能効果を十分発
揮し、２μｍを超えるとコストアップを招く割に耐食性
がそれ以上向上する訳ではないので０．１〜２μｍが好
ましい。On the other hand, if the thickness is 0.1 μm or more, the anticorrosion effect will be sufficiently exhibited, and if it exceeds 2 μm, the corrosion resistance will not be improved any further, although the cost will increase, so 0.1 to 2 μm is preferable.

コスト等からも工業的に適用するのは難しい。The plating method is to form a homogeneous fine plating structure, so Zn and Mg are evaporated from separate crucibles under reduced pressure to form a Zn-Mg alloy plating layer, and then Zn
Particularly preferred is vapor deposition plating in which the Zn layer or Zn alloy layer is formed by evaporating the alloying element alone or with Zn from a separate crucible. On the other hand, if the lower Zn-Mg alloy layer is formed by a method other than vapor deposition plating, such as hot-dip plating, the plating bath temperature must be raised above the melting point of each metal during hot-dip plating. In high-temperature plating, an intermetallic compound consisting of the base metal and the plating metal is formed, impairing workability, and in electroplating and chemical plating, Zn-Mg or Zn
Alternatively, precipitation of Zn alloys is not possible. In principle, non-aqueous solution plating is also possible, but it is difficult to apply it industrially due to the low current density and poor plating efficiency, the instability of the plating solution, and the manufacturing cost.
