[従来技術]
従来、自動車、家庭電気用品等には種々の防錆鋼板が使
用されているが、そのうちZnの優れた犠牲防蝕作用に
よりZnめっき鋼板が尤も広く用いられている。[Prior Art] Conventionally, various rust-proof steel sheets have been used in automobiles, household electrical appliances, etc., but among them, Zn-plated steel sheets are particularly widely used due to the excellent sacrificial corrosion-preventing action of Zn.
しかし、荀酷な腐蝕環境下ではZnの溶出による消費が
早まり、めっきとしての寿命が短くなるため、他の金属
を合金化さ仕耐蝕性を向上させた7、n合金めっき鋼板
か開発されてきており、需要ら益々増加の傾向を示して
いる。However, in a severely corrosive environment, Zn is leached out and consumed quickly, shortening the life of the coating. Therefore, 7,N alloy plated steel sheets have been developed that are alloyed with other metals and have improved corrosion resistance. This trend shows an increasing trend due to demand.
そして、このZn合金めっき調板としては、Zn−Fe
5Zn−Ni、Zn−Co等の合金めっき鋼板があり、
主として電気めっきにより製造されている。As this Zn alloy plating plate, Zn-Fe
There are alloy plated steel sheets such as 5Zn-Ni and Zn-Co.
Mainly manufactured by electroplating.
しかしながら、近年耐蝕性向上の要求が強くなり、これ
らの合金めっき層の厚膜化が必要となっているが、電気
めっき法では厚目付けの操作が複雑となり、かつ、コス
トが大幅に上昇するという問題がある。However, in recent years there has been a strong demand for improved corrosion resistance, and it has become necessary to thicken these alloy plating layers, but with electroplating, the operation of applying thick coatings is complicated and the cost increases significantly. There's a problem.
そのため、この問題を解決した鋼板としては、従来より
次のような粉末めっき法を適用した鋼板がある。Therefore, as steel sheets that have solved this problem, there are conventional steel sheets to which the following powder plating method is applied.

A steel plate with U alloy plating (brass plating) is described (Conventional Example A).

毎でも大きくばらつく。However, both conventional examples A and B described above have a common problem with IrL in terms of workability, as will be explained below. That is,
In Conventional Example A, part of the powdered Zn easily diffuses into the base iron due to slight fluctuations in heating conditions during operation, and in Conventional Example A, part of the plated Zn diffuses into the base iron, causing the plating to deteriorate. Since a hard and brittle Zn--Fe alloy layer is formed at the interface of the base iron of the layer, the workability varies greatly even for the same sheet thickness or from one chance to another.

After adhering the Zn powder, the steel plate is heated and alloyed so that a part of the electroplated layer remains, and the workability of the steel plate having the Zn alloy plating layer is greatly improved. Surface gloss is also improved by providing a Zn plating layer formed by heating the powder.
先ず、本発明に係る耐蝕性、加工性のに優れた多層合金
めっき鋼板の第1層について説明する。First, the first layer of the multilayer alloy plated steel sheet having excellent corrosion resistance and workability according to the present invention will be explained.
好適なめっき法としては、1)めっき欠陥の少ないこと

Ni and Co do not form a brittle alloy layer and have significantly improved corrosion resistance compared to Zn when alloyed with Zn powder. , CrCu, or alloys of two or more of these metals, and the above pure metals, alloys, and Zn.
An alloy with is not suitable.

いため、そのアンカー効果により塗膜密着性が向上する
からである。Next, the second layer is a Zn alloy plating layer obtained by heating and alloying a part of the electroplating layer and Zn powder. This is because the surface roughness is larger than that of the alloy plating layer, so the anchor effect improves the adhesion of the coating.
さらに、第2層の上に第3層としてZn粉末を加熱して

表面光沢をさらに向上させるためには、加熱前或いは加
熱後に冷間圧延を行うと良い。Furthermore, as mentioned above, providing the Zn plating layer obtained by heating Zn powder as the third layer on the second layer is
The plated surface alloyed by heating has good coating film adhesion, but is poor in surface gloss. Therefore, when appearance characteristics are required, a Zn powder plating layer as a non-diffusion layer is provided. However, with alloy powders, composition differences tend to occur between the vicinity of the contact surface and inside the powder particles, which deteriorates corrosion resistance, whereas with single metal powders this can be prevented, so pure Zn powder is used as the powder. It is. Also,
In order to further improve the surface gloss, cold rolling may be performed before or after heating.
