Evaluation of Corrosion Inhibitor Additives for Alkaline Flight Deck Cleaning Solutions.

摘要

The flight deck cleaning detergent specified by NAVSHIPS Bulletin is a highly alkaline, 3% sodium metasilicate solution. It was found to accelerate corrosion of the aluminum track covers on the USS Roosevelt. Laboratory tests showed that sodium naphthenate at a proper concentration inhibits corrosion of aluminum in alkaline solutions. However, sodium naphthenate degrades the cleansing ability of the metasilicate/detergent solution on certain soiling mediums. Thus, it does not appear feasible to use sodium naphthenate as an additive in deck cleaning solutions. (Author)
