Abstract
Description
[1]Al:1.0mass%超え15mass%以下を含有し、残部がZn及び不可避的不純物からなる溶融Zn−Al系めっき皮膜を有する溶融Zn−Al系めっき鋼板の表面に、膜厚3.0μm以下の化成皮膜を有し、
前記化成皮膜は、Mg、Ca、Srから選ばれる1種以上の元素を含有した化合物およびAlH2P3O10・2H2Oを合計で3.0〜50mass%含有する表面処理鋼板。
[2]前記Mg、Ca、Srから選ばれる1種以上の元素を含有した化合物は、MgO、MgAl2O4、CaO、SrOから選ばれる1種以上の酸化物である[1]に記載の表面処理鋼板。
[3]前記化成皮膜は、SiO2をさらに含有し、前記SiO2、前記Mg、Ca、Srから選ばれる1種以上の元素を含有した化合物、および前記AlH2P3O10・2H2Oを合計で3.0〜50mass%含有する[1]または[2]に記載の表面処理鋼板。
[4]さらに、前記溶融Zn−Al系めっき皮膜は、Mg:0.1〜10mass%を含有する[1]〜[3]のいずれかに記載の表面処理鋼板。
[5]さらに、前記溶融Zn−Al系めっき皮膜は、Si、Ca、Ti、Cr、Niから選ばれる1種以上の元素を合計で0.01〜1.0mass%含有する[1]〜[4]のいずれかに記載の表面処理鋼板。
めっき浴中のSi、Ca、Ti、Cr、Niから選ばれる1種以上の元素の合計含有量が0.01mass%未満では、上記に示した効果が十分に得られない。一方、合計含有量が1.0mass%を超えると、各効果が飽和するだけでなく、多量発生するドロスの付着により、外観品位が損なわれる場合がある。よって、めっき浴中のSi、Ca、Ti、Cr、Niから選ばれる1種以上の元素を含有させる場合の合計含有量は、0.01〜1.0mass%とする。
さらに、めっき浴の成分調整と管理の観点から、Si、Ca、Ti、Cr、Niは、単独で含有させることがより好ましい。
<めっき皮膜組成の測定>
サンプルとなる溶融Zn−Al系めっき鋼板を100mmφに打ち抜き、発煙硝酸に浸漬してめっき皮膜(界面合金層を除くめっき層)を剥離させた。その剥離液に塩酸を加えて溶け残りのAlを完全に溶解させた後、溶液をICP発光分光分析することで組成を確認(測定)した。なお、化成皮膜の厚さは、表面処理鋼板を冷凍かち割り加工し、皮膜破断面を走査型電子顕微鏡(SEM)で観察し、測定した。
<めっき密着性の評価>
サンプルとなる溶融Zn−Al系めっき鋼板を50mm×50mmに剪断し、撃心径が3/8インチ、おもり重量が1.0kg、落下高さが1000mmの条件でデュポン衝撃試験を行った。試験後の張り出し部外面にセロハンテープを強く貼り付けた後、引き剥がし、張り出し部外面の状態、及びセロハンテープの状態から、下記の基準でめっき密着性を判定した。
5点(合格):クラックや剥離がない
4点(合格):微小クラックがあるが剥離がない
3点(合格):クラックがあるが、剥離がない
2点(不合格):わずかに剥離あり
1点(不合格):顕著な剥離あり
<端部耐食性の評価>
表面処理鋼板を70mm(上下)×150mm(左右)サイズに剪断後、評価面の上下の端部10mm及び非評価面(背面)にテープでシール処理を施し、左右各150mmの剪断端部を露出させたものをサンプルとした。この評価用サンプル(図1)を用いて、塩水噴霧試験(SST):JIS Z2371を480時間実施し、剪断端部から進行するめっき表面の錆長さ(端部からの最大腐食幅)を測定し、下記の基準で端部耐食性を評価した。
A:最大腐食幅≦20mm
B:最大腐食幅≦25mm
C:最大腐食幅>25mm
結果を表1、2に示す。
