g-based plating is applied.

べき効果がある。Mg content in the plating layer: 1 to 4% by weight Mg contained in the plating layer causes a Zn-based corrosion product containing Mg to be formed on the outermost layer of the plating layer, and together with Al in the plating layer, the general atmosphere. This has the effect of reducing the corrosion rate of the plating layer under the environment. This effect is due to the fact that Zn-based corrosion products containing Mg are stably present on the plating layer for a long period of time, and the formation of zinc oxide that deteriorates corrosion resistance is suppressed. In addition, some of the Zn-based corrosion products containing Mg flow into the cut end face generated by cutting or the like and the non-plated portion generated by spot welding, etc., and have a remarkable effect of suppressing corrosion of iron on the end face. is there.

制する。[0011] When a plurality of metals such as stainless steel and aluminum alloy are used as a vehicle member, it is conceivable that different metals corro- late with the metals.
The plating layer is initially corroded by the corrosion of the dissimilar metal, and a Zn-based corrosion product containing Mg is generated there, and further corrosion is suppressed by covering the interface between the dissimilar metal and the plating layer.

成分である。Further, the addition of Mg makes the plating layer hard, which suppresses the occurrence of scratches which are less likely to be scratched and which can be the starting point of rust, and are particularly suitable for parts around the vehicle, under floors and the like. . This is because the intermetallic compound Z in the plating layer
This is because n 2 Mg is uniformly and finely dispersed.
n 2 Mg is a component of the ternary eutectic solidification structure of Zn / Al / Zn 2 Mg.

製造性が悪くなる。Al content in the plating layer: 4 to 22% by weight Zn and Mg in the plating layer form Zn-based corrosion products containing Mg, whereas Al in the plating layer has extremely strong adhesion. It forms Zn-Al-based corrosion products and contributes to improvement of corrosion resistance. Further, when Al is contained in the plating layer, Zn / Al / Zn 2 Mg ternary eutectic appears in the solidification structure of the plating layer. Since the ternary eutectic structure is finer than the Zn / Zn 2 Mg binary eutectic structure, the ternary eutectic structure is more preferable from the viewpoint of corrosion resistance and plating layer hardness. However, even if Al is added in excess of 22% by weight, the above effect is saturated, and the melting point of the plating metal increases with an increase in the Al content, so that it is necessary to maintain the plating bath at a high temperature. become worse.

いためにめっき層の腐食が急速に進行する。It is assumed that Zn- in which the plating layer contains no Al
In the case of the Mg-based alloy, when the Mg-containing Zn-based corrosion product flows out, the corrosion of the plating layer rapidly progresses because there is no Zn-Al-based corrosion product having strong adhesion to the base.

A Ti—Al-based precipitate grows on the surface of the plating layer, and irregularities are formed on the plating layer, thereby impairing the appearance. Also,

The 1-Mg-based plated steel sheet (member) has an effect of suppressing the phenomenon of “deterioration of the surface gloss of the plating layer” which is unique to the present steel sheet. "Degradation of surface gloss of plating layer" is a phenomenon in which a plated surface having a beautiful metallic luster changes to a gray color as time passes immediately after production, and is not preferable in terms of surface appearance. Such a discoloration phenomenon is caused by adding at least one of rare earth elements, Y, Zr, and Si to 0.005.
It can be suppressed by adding more than weight%. However, the effect is saturated even if it is added in excess of 2.0% by weight, so it is preferable to add 0.005 to 2.0% by weight.

が、めっき層中にＳｉを微量含有させることでこの問題
は回避される。Further, as the Al content of the plating layer becomes higher, an Fe-Al intermetallic compound is locally generated at the interface between the plating layer and the steel base, so that the plating is partially performed when forming the plated steel sheet. Although there is a concern that the layer may be peeled off, this problem can be avoided by including a small amount of Si in the plating layer.

な外観を得ることができる。The plated steel sheet (member) can be subjected to a chromate or non-chromium (environment-friendly) chemical conversion treatment to improve corrosion resistance and coating adhesion. Further, if an organic resin coating of about several μm is applied after the chemical conversion treatment, corrosion resistance and scratch resistance are further improved, and when a lubricating component is contained in the resin, molding into various members becomes easy. Further, by applying a coating to the plating surface depending on the use site (corrosive environment) of the vehicle, it is possible to enhance the corrosion resistance and obtain a beautiful appearance.

Further, since the plating layer is hard and not easily damaged, it is possible to suppress the generation of scratches that can be a starting point of rust.
