Abstract
【解決手段】 結露するまで湿度を変化させ、この変化に伴う塗膜の表面電位変化の挙動を検知し、腐食の起点となる塗膜と金属界面の濡れ性を評価する。
【選択図】 図6
Description
b)において、それぞれの右縦列等間隔の電流変化は0.2V毎の単位で表わされている。なお、この場合、走査範囲20mm×20mmである。これによれば、親水性の塗膜を用いた場合、相対湿度30%における表面電位分布の変化と相対湿度80%における表面電位分布の変化をそれぞれ示しており、図7(a)→(b)と湿度の増加に伴って電位変化が起こっていることが示され、親水性塗膜では湿度を80%まで増加したのみで表面電位は平均0.7V低下した。一方、撥水性塗膜では結露させてもしばらくは表面電位の変化は見られなかった。
