Description
59Co+n→60Co
厚みを種々変化させた導電性中間層と機能層を基材表面に設けた試験片を作製し、この試験片に電磁波を照射したときの自然浸漬電位を測定し、この電位に基づいて腐食電位低下性(耐応力腐食割れ性)を評価した。なお、電磁波照射の影響を充分無視できるように参照電極は鉛ブロックで遮蔽している。
◎◎:非常に優れている(自然浸漬電位が、−350mV以下)
◎ :優れている(自然浸漬電位が、−350mV超〜−300mV)
○ :良好(自然浸漬電位が、−300mV超〜−250mV)
△ :普通(自然浸漬電位が、−250mV超〜−200mV)
□ :効果はあるが小さい(自然浸漬電位が、−200mV超)
◎:剥離面積が10%以下(良好)
○:剥離面積が10%超〜20%
△:剥離面積が20%超〜50%
□:剥離面積が50%超〜60%
×:剥離面積が60%超(不良)
次に、基材表面に設ける導電性中間層と機能層の種類を変えた試験片を作製し、この試験片について腐食電位低下性と密着性を評価した。
