Description
肉厚が5mmのCu板を12mm角にくり抜き加工しCuからなる基材を作製した。更に、その基材の表面をリン酸溶液で電解研磨し鏡面にした。そして、図1で説明したのと同様にして、上記基材の表面にNi−P合金めっき膜およびAuからなる表層めっき膜を順次に形成し金属めっき皮膜とした。ここで、Ni−P合金めっき膜および表層めっき膜の膜厚は、それぞれ略0.3μm、略0.2μmである。このようにして、Cu基材に金属めっき皮膜を有する種々のテストピースを作製した。
図5の実施例1,2に示されるように、電解めっき法で形成されるNi−P合金めっき膜は、そのP含有量が10質量%以上になれば、加熱処理前、180℃、270度の加熱処理後のいずれにおいても非磁性となる。しかし、比較例1に示されるように、P含有量が9質量%に下がると、270℃の加熱処理後のテストピースに磁性の現れるところが出てくる。P含有量が6質量%になる比較例2では、加熱処理前、180℃、270℃の加熱処理後のいずれにおいても磁性となる。
Claims (3)
