Abstract

A 1, 2-bis (triethoxysilyl) ethane (BTSE) is coated to build up self-assembled monolayers (SAM) on the surface of iron for protecting from in-door atmospheric corrosion. To close the terminals of SAM molecule, a water repellent agent octadecyltrimethoxysilane (ODTMS) is coated further on BTSE coated film. For corrosion test to evaluate corrosion-resistant property, accelerated corrosion test was performed in a thermohygrostat kept at 40°C and 40% relative humidity. Also, anodic polarization measurement was performed. It is found that the ODTMS coating on BTSE coated film shows high corrosion resistance by anodic polarization measurement and an accelerated corrosion testing.
