Abstract
【解決手段】 アルミニウム合金からなる基板上に形成され、亜鉛、チタン及びニオブから選ばれた1種又は2種上を0.1〜10vol%含有する三フッ化樹脂からなり、自己修復性に優れている。この場合においてアルミニウム合金を熱交換器とすることができる。
【選択図】 図1
Description
(1)塗膜試験片の塗膜面にカッターナイフにより塗膜を貫通し基板に到達する傷を刻む。
(2)塩酸によりpH:1に調整された3mass%の食塩水からなる腐食試験液を準備し、これに前記(1)により傷を刻んだ試験片を浸漬して温度70℃で所定時間保持する。
(3)所定時間経過後塗膜試験片を試験液から取り出し、外観を観察するとともに図2にその概略構成を示す電気化学インピーダンス測定装置を用いて、試験片に±10mVの交流を0.01Hz〜20kHzの範囲で変化させてそのインピーダンスおよび位相差を測定する。
(4)低周波域(0.1〜0.01Hz)で測定されるインピーダンス(R)を腐食抵抗とし、その浸漬12h値(R12)を基準値として規格化した値(R/R12)を腐食抵抗比とした。
