摘要：

Protective layer formation of alpha,omega-diphosphono-alkane compounds on iron surface was studied. Layer formation proved to be a spontaneous process on iron, and can be accomplished by simple immersion into an aqueous solution of phosphono compounds, resulting in a thin dense multimolecular adsorption layer with a high corrosion protection effect. The mechanism of inhibition and time dependence of layer formation is presented. (C) 2004 Elsevier Ltd. All rights reserved.
