초록

인공해수에서 일어나는 Al의 부식에 대하여 alanine과 methionine의 부식억제 효과를 조사하였다. 이들 아미노산의 낮은 덮힘율로 보아 Al 표면에 alanine과 methionine는 Langmuir adsorption isotherm에 따른 흡착이 일어나며, 아미노산 안의 카르복시 이온만이 Al에 흡착하는 것으로 보인다.

Abstract

Inhibition effects of alanine and methionine on the corrosion of aluminum were investigated in artificial sea water. Based on the low coverage of alanine and methionine we suggested that alanine and methionine adsorption process in aluminum surface is Langmuir isotherm and the carboxyl ion of amino acids seems to be adsorbed on Al.
