Description
上記実施形態では、溶接側Ni層11の厚みt1と非溶接側Ni層12の厚みt2とを略等しくした例を示したが、上記実施形態の変形例として、溶接側Ni層11の厚みt1と非溶接側Ni層12の厚みt2とを異ならせてもよい。この場合、溶接側Ni層11の厚みt1は、リード材1の厚みt3の約2.1%以上約8.2%以下である一方、非溶接側Ni層12の厚みt2は、リード材1の厚みt3の約2.1%未満であってもよいし、リード材1の厚みt3の約8.2%よりも大きくてもよい。ここで、非溶接側Ni層12の厚みt2は、非溶接側Ni層12の表面上に異物が残存するのをより確実に抑制するために、リード材1の厚みt3の約1.3%以上約8.4%以下であるのがより好ましい。
次に、図2〜図11を参照して、本実施形態による効果を確認するために行った接合強度評価試験、電極溶着評価試験および耐食性評価試験に関する確認実験について説明する。
次に、接合強度評価試験について説明する。この接合強度評価試験では、図4に示すように、抵抗溶接された試験材1〜8のリード材1(101)と溶接母材5とを、互いに反対の方向に10mm/分の速度で引っ張り、溶接箇所が破断した際の引張強度を接合強度として求めた。
次に、電極溶着評価試験について説明する。この電極溶着評価試験では、抵抗溶接による溶接後において、図4に示す電極4a(図3参照)が配置されていた試験材1〜8の電極配置位置6における非溶接側Ni層12(112)の表面上を電子線マイクロアナライザ(EPMA)によって分析し、電極4aに含まれるCuの溶着の有無を確認した。具体的には、試験材1〜8の電極配置位置6内の任意の直線上における非溶接側Ni層12(112)の表面上のCuの濃度を分析し、Cuの濃度が73.5%以上である測定位置が存在する場合には、Cuの溶着がある(有判定)と判断した。一方、Cuの濃度が73.5%以上である測定位置が存在しない場合には、Cuの溶着がない(無判定)と判断した。
最後に、確認実験として行った耐食性評価試験について説明する。この確認実験では、Niからなる板材と、Ni−Fe合金からなる板材との耐食性の評価を行った。具体的には、Niからなる板材、50%のFeを含むNi−50Fe合金からなる板材、58%のFeを含むNi−58Fe合金からなる板材、62%のFeを含むNi−62Fe合金からなる板材および64%のFeを含むNi−64Fe合金からなる板材を試験材として用いて耐食性評価試験を行った。耐食性評価試験は、JISZ2371の「塩水噴霧試験方法」に準じて、35℃の温度条件下で、5%(50g/L)NaCl水溶液を24時間連続的に試験材に噴霧することによって行った。そして試験後の試験材の腐食状態を観察することによって試験材の耐食性を評価した。なお、腐食状態は、図10に示す腐食面積割合の判断基準(JISレイティングナンバ)を参照して、一定面積に対する腐食面積の割合を基準に判断した。
