“…Up to date, IP6 and its salts have been used as additive agent for copper and its alloys [21][22][23][24][25], magnesium alloys [26][27][28], aluminium alloys [29], etc., and their anticorrosive efficiency could reach 90% or more. In addition, the inhibiting mechanisms of IP6 for the metals mentioned above have been studied and can be classified into two types in general: one is to form an adsorption film of IP6 on metal surface by chemisorption [30][31][32] and the other is to act as a conversion coating by forming complexes with metal ions [26,27,33]. However, few works could be found in literature concerning the inhibiting effect and mechanism of IP6 on carbon steel in simulated concrete solutions.…”

“…In [71], the CCs formed on galvanized steel after preliminary immersing the samples for 10 s in an aqueous solution of 0.05 M H 2 SO 4 + 0.5% H 2 O 2 , then washed with distilled water and ethanol and dried in a hot air stream were studied. After that, the samples were immersed in a hot alkaline solution (50°C) for 5 min, washed with water, and the first operation was repeated.…”

This article continues the review of studies (2006)(2007)(2008)(2009)(2010)(2011)(2012)(2013)(2014)(2015)(2016) dealing with the passivation of various metals by solutions of organic corrosion inhibitors. It provides an overview of papers on the passivating properties of organophosphates, their complexes and salts. The results of corrosion and electrochemical studies, as well as studies on the composition and structural features of surface layers on metals by a variety of physicochemical methods are considered. Organic phosphorus compounds are often called organophosphates, especially in the case of pesticides and even toxic agents. Of course, it is unlikely that such materials have application prospects for the inhibition of metal corrosion. That is why in this series of reviews we consider organophosphates in a narrower sense limited to phosphoric acid esters and their salts, as well as phosphonic acids, their salts or complex compounds with metal cations [1][2][3][4]. The easy synthesis of acid esters of phosphoric acid, the stability of mono-and disubstituted ester anions, their ability to form complexes and hydrophobic passive films on oxidized metal surfaces has been known for a long time [1]. They can be used for the passivation of phosphated metal surfaces, and their salts with amines are used within deicing formulations. These salts can inhibit not only corrosion but also formation of deposits, so they are used in two-phase systems in the oil industry. Since higher homologues are more effective, the solubility of alkylphosphonic acids is commonly increased by ethoxylation. Salts of these acids are used in cooling lubricants, e.g., waterbased cutting fluids. The low toxicity, ability to be chemisorbed on a metal surface, and some useful technological properties of acid esters of phosphoric acid continue to motivate researchers to look for effective corrosion inhibitors of various metals among these compounds and to study their protection mechanisms [5][6][7][8][9][10][11][12][13][14]. Key words: metal corrosion, inhibitors, metal passivation, organophosphates.

“…Quantum chemical calculations showed that the quality of self-assembled films is related to the structural properties of the self-assembled molecules [15,16] . Molecular dynamics simulations revealed the adsorption configuration and the adsorption strength of self-assembled molecules adsorbed on a metal surface [17,18] .…”
