经磷酸盐处理的电镀锌钢板
摘要：
本发明的经磷酸盐处理的电镀锌钢板，在电镀锌层之上具有磷酸锌被膜，所述电镀锌层的结晶面(00·2)、(10·0)及(10·1)的取向指数Ico(hk·1)满足下式(1)～(3)的必要条件。4.0≤Ico(00·2)…(1)，0＜Ico(10·0)≤0.020…(2)，0＜Ico(10·1)≤0.20…(3)，(上式中，Ico(hk·1)是结晶面(00·2)、(10·0)、(10·1)、(10·2)、(10·3)及(11·0)的Willson的6面取向指数。)根据这一结构，其会显示出L值为70.00以上的特别高的亮度。
摘要（英）：

A phosphate treated electrolytic galvanized iron is provided to keep the brightness high after the phosphate treatment. A phosphate treated electrolytic galvanized iron comprises an electric zinc plating layer and a phosphate zinc film. The phosphate zinc film is coated on the electric zinc plating layer. The orientation index Ico(hk.1) of the crystal plane of the electric zinc plating layer is satisfied the following conditions. 4.0<=Ico(00.2), 4.0<=Ico(00.2), 0
