Zn合金めつき鋼板に関する。[Detailed Description of the Invention] [Industrial Field of Application] The present invention provides an Al-
Regarding Zn alloy plated steel sheets.
Alめつき鋼板は良好な美観を有し、かつ耐食
性も特殊の環境を除けば、Znめつき鋼板の３〜
４倍の性能を有すると言われている。しかしなが

Al-plated steel sheets have a good appearance, and their corrosion resistance is about 30% higher than that of Zn-plated steel sheets, except in special environments.
It is said to have four times the performance. However, in an environment where Cl - ions exist, such as a marine environment, pitting corrosion tends to occur in the plating film, which corrodes the plating substrate and eventually causes perforation.
Al−Zn合金めつき鋼板は、Alめつき鋼板より
更に高い耐食性を有し、特にCl-イオン環境下で
格段に優れた耐食性を有することが知られ、種々
の組成で実用化が進んでいる。しかしながら、こ
れら鋼板の殆どはAlめつき鋼板と同様の溶融め
つき法にて製造されているため、次の如き問題が
あつた。 Al-Zn alloy plated steel sheets are known to have higher corrosion resistance than Al-plated steel sheets, especially in Cl - ion environments, and are being put into practical use in various compositions. . However, since most of these steel plates are manufactured by the same hot-dip galvanizing method as Al-plated steel plates, they have the following problems.
溶融めつき法では、薄めつきが困難でありめつ
き皮膜が一般に20〜40μｍ（150〜300ｇ／m2）と
厚く加工性、溶接性が劣ると共に経済的に不利で
ある。
In the hot-dip plating method, thinning is difficult and the plating film is generally as thick as 20 to 40 μm (150 to 300 g/m 2 ), resulting in poor workability and weldability and is economically disadvantageous.
又めつき溶温度が高温（約700℃以上）のため
めつき層と母材間に金属間化合物の生成、母材へ
の悪影響、更には浴成分のAlの酸化によるAl2O3
ドロスの発生によりめつき皮膜中にこのAl2O3を
巻き込んだりし、耐食性の向上を阻害する問題点
を有していた。 Also, because the plating melting temperature is high (approximately 700°C or higher), intermetallic compounds are formed between the plating layer and the base material, which has an adverse effect on the base material, and furthermore, Al 2 O 3 due to the oxidation of the bath component Al.
There was a problem in that this Al 2 O 3 was involved in the plating film due to the generation of dross, which inhibited improvement in corrosion resistance.
本発明の目的は、薄目付でありながら耐食性に
優れ、しかもAl2O3の巻き込みや金属間化合物の
形成がないAl−Zn合金めつき鋼板を提供するこ
とにある。 An object of the present invention is to provide an Al--Zn alloy plated steel sheet that has a low basis weight but has excellent corrosion resistance and is free from entrainment of Al 2 O 3 and formation of intermetallic compounds.

果の得られることが知見された。
Plating methods are broadly divided into dry plating and wet plating, and dry plating is further divided into melt plating, gas phase plating, and solid phase plating depending on the condition of the coated metal. The above-mentioned melt plating method is classified as melt plating, but the present inventors focused on vapor phase plating, particularly vacuum vapor deposition plating, and found that
We planned to perform Al-Zn alloy plating. As a result of repeated various experimental studies, we found a specific
It has been found that a particularly remarkable effect of improving corrosion resistance can be obtained within the Zn content range.
本発明はこの知見に基づきなされたもので、
Znを５〜25wt％含有し残部が実質的にAlよりな
る付着量３〜20ｇ／m2の真空蒸着めつき層を有す
ることを特徴とするAl−Zn合金めつき鋼板を要
旨とする。 The present invention was made based on this knowledge,
The gist of the present invention is an Al-Zn alloy plated steel sheet characterized by having a vacuum-deposited plating layer containing 5 to 25 wt% of Zn and the remainder being substantially Al with a coating weight of 3 to 20 g/ m2 .
真空蒸着によるAl−Zn合金めつきがZnめつき、
純Alめつきと比較して耐食性に優れる理由は下
記のように考えられる。 Al-Zn alloy plating by vacuum evaporation is Zn plating,
The reason why it has superior corrosion resistance compared to pure Al plating is thought to be as follows.
第１図は真空蒸着法にてZnを15wt％含有する
Al−Zn合金をめつきした供試材をSST（塩水噴霧

This figure shows the results of a quantitative investigation of the behavior of a specimen plated with Al-Zn alloy using SST (salt spray test). ) was analyzed and displayed.

Two types of test materials (0wt%Zn and 15wt%
%Zn), the state of Al at 100 Å on the surface was analyzed and displayed using ESCA.
同図ａ，ｃに見るように、Al−Zn合金めつき
層中のZnはSSTの時間経過とともに酸化が進む。
また、同図ｂに示すように、Alは酸化が進む。
しかし、同図ｄに見るように、合金としてZnが
含有されることにより、Alの酸化速度は遅くな
る。このことは、合金としてZnが含有されるこ
とにより、Znの優先腐食が起つてAlの腐食が抑
制される。更にはAl−Znの混合腐食皮膜は非常
に緻密であり長時間の腐食に耐えられる。このよ
うな理由によりAl−Zn合金めつきはAlめつきよ
りも耐食性に優れるものと考えられる。 As seen in Figures a and c, Zn in the Al-Zn alloy plating layer progresses to oxidize as time passes during SST.
Furthermore, as shown in Figure b, oxidation of Al progresses.
However, as shown in Figure d, the oxidation rate of Al becomes slow due to the inclusion of Zn as an alloy. This means that by containing Zn as an alloy, preferential corrosion of Zn occurs and corrosion of Al is suppressed. Furthermore, the mixed corrosion film of Al-Zn is very dense and can withstand corrosion for a long time. For these reasons, Al-Zn alloy plating is considered to have better corrosion resistance than Al plating.
そして、真空蒸着法は、前記した溶融めつき法
に比べ薄めつきが可能であり、この薄めつきによ
つて加工性、溶接性が向上すると共に、薄めつき
でありながら従来の厚めつきと同等或いはより以
上の耐食性が得られ経済的に有利となる。 The vacuum evaporation method allows for thinner coating than the above-mentioned melt plating method, and this thinning improves workability and weldability, and although it is thinner, it is equivalent to or equivalent to conventional thick coating. This provides better corrosion resistance and is economically advantageous.
また、真空蒸着法では真空中でのAlの酸化が
殆ど皆無でありAl2O3の発生及び被覆中への巻き
込みが発生せず、又基板の温度が上昇しないこと
から金属間化合物の生成もなく、これらによる耐
食性低下の懸念もない。 In addition, with the vacuum evaporation method, there is almost no oxidation of Al in vacuum, so there is no generation of Al 2 O 3 or entrainment into the coating, and the temperature of the substrate does not rise, so there is no formation of intermetallic compounds. There is no concern that corrosion resistance will deteriorate due to these factors.
本発明のめつき鋼板において、めつき層中の
Zn含有量を５〜25wt％の範囲に限定したのは、
次の理由による。 In the plated steel sheet of the present invention, in the plated layer
The reason for limiting the Zn content to the range of 5 to 25 wt% is that
Due to the following reasons.
Zn含有率が5wt％未満では、Znの優先腐食が
少なくAlの腐食抑制効果が小さく十分な耐食性
が得られない。 When the Zn content is less than 5 wt%, preferential corrosion of Zn is small, and the effect of suppressing corrosion of Al is small, and sufficient corrosion resistance cannot be obtained.
一方Zn含有率が25wt％を超えるとZnの優先腐
食量が必要以上に増し、Zn主体の酸化皮膜が形
成されてくる。この皮膜はZnCl2・4Zn（OH）2及
びZnOの組成をもち特に後者は比較的ポーラスな
構造で、耐食性に寄与するところが少なく、これ
に占有されることによつて耐食性が低下する。 On the other hand, when the Zn content exceeds 25 wt%, the amount of preferential corrosion of Zn increases more than necessary, and an oxide film consisting mainly of Zn is formed. This film has a composition of ZnCl 2 .4Zn(OH) 2 and ZnO, and the latter in particular has a relatively porous structure, contributes little to corrosion resistance, and is occupied by this, thereby reducing corrosion resistance.
以上のことから、本発明では、その含有率を５
〜25wt％、より好ましくは10〜20wt％とするも
のである。 From the above, in the present invention, the content is reduced to 5.
~25wt%, more preferably 10~20wt%.
又本発明の鋼板におけるめつき付着量は、３〜
20ｇ／m2とする。 Furthermore, the amount of plating on the steel plate of the present invention is 3 to 3.
20g/ m2 .
３ｇ／m2未満では十分なる耐食性が得られず20
ｇ／m2超えでは、加工性、溶接性が悪化するのみ
ならず、より以上の耐食性向上が望めず経済的に
不利である。 If it is less than 3g/ m2 , sufficient corrosion resistance cannot be obtained20
If it exceeds g/m 2 , not only will workability and weldability deteriorate, but further improvement in corrosion resistance cannot be expected, which is economically disadvantageous.
本発明の鋼板におけるめつき付着量およびZn
の含有率は、例えば次のようにして求めることが
できる。 Plating amount and Zn in the steel sheet of the present invention
The content rate can be determined, for example, as follows.
鋼板から所定面積の試料を採取する。その試料
を所定濃度の酸溶液（例えば２％％Cl溶液）に浸
漬して、めつき皮膜を溶解する。次いで、その酸
溶液を付着量等に応じて希釈し、ICP発光分光分
析法等にて酸溶液のZn濃度およびAl濃度を求め
る。 A sample of a predetermined area is taken from the steel plate. The sample is immersed in an acid solution of a predetermined concentration (for example, a 2% Cl solution) to dissolve the plating film. Next, the acid solution is diluted according to the amount of adhesion, etc., and the Zn concentration and Al concentration of the acid solution are determined by ICP emission spectrometry or the like.
求めたZn濃度をａ（ｇ／）、Al濃度をｂ（ｇ／
）とし、溶解に使用した酸溶液の量をｍ（）
とする（ここでは簡単なため希釈せずに分析を行
つたとする）。そうすると、Znの溶解量はａ・ｍ
（ｇ）となり、Alの溶解量はｂ・ｍ（ｇ）となる。
ここで、試料の面積がＳ（m2）であつたとすれば、
めつき付着量は（ａ＋ｂ）・ｍ／ｓ（ｇ／m2）とな
り、Znの含有率はａ／ａ＋ｂ（wt％）となる。 The determined Zn concentration is a (g/), and the Al concentration is b (g/
), and the amount of acid solution used for dissolution is m()
(Here, it is assumed that the analysis is performed without dilution for simplicity). Then, the amount of Zn dissolved is a・m
(g), and the amount of dissolved Al is b·m (g).
Here, if the area of the sample is S (m 2 ), then
The plating amount is (a+b)·m/s (g/m 2 ), and the Zn content is a/a+b (wt%).
なお、めつき皮膜を溶解させる際に懸念される
母材の溶解については、充分に希釈された酸溶液
を使用すれば、めつき皮膜と母材の溶解速度が異
なるため、例えば処理時間を決めておくなどの比
較的容易な対策により、めつき皮膜のみを溶解さ
せることができる。また、母材に含まれるZnお
よびAlは微量であるので、仮に母材が溶解して
も分析への影響は無視できる程度である。 Regarding the dissolution of the base material, which is a concern when dissolving the plating film, if a sufficiently diluted acid solution is used, the dissolution rate of the plating film and the base material will be different, so for example, the treatment time may be determined. Only the plating film can be dissolved by relatively easy measures such as keeping it in place. Furthermore, since the base metal contains trace amounts of Zn and Al, even if the base metal were to dissolve, the effect on the analysis would be negligible.
次に実施例を述べる。なお、実施例の中の目付

In addition, despite its light weight, it has outstanding corrosion resistance. Furthermore, since there is no inclusion of Al 2 O 3 or intermetallic compounds, deterioration in corrosion resistance due to these is also prevented.
