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 mono-and diphosphonic acids and their 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.

“…Self‐assembled monolayers (SAMs) have been widely used in recent years to this end due to their durability and relative ease of preparation . Reports shows that SAMs form on a variety of surfaces; eg, Al 2 O 3 or copper oxide, SiO 2 , and metals like Au and Ag . Molecules that form SAMs possess a linker group that can interact with surface sites (eg, CO 2 H or SH) and an alkyl or perfluoroalkyl chain that points away from the surface .…”

Desorption of carboxylates and phosphonates from galvanized steel: Towards greener lubricants

This paper studies the removal of chemisorbed carboxylates and phosphonates from TiO2‐coated galvanized steel using NaOH(aq). XPS and FTIR data show that NaOH(aq) is effective at desorbing these species and so is an alternative to gas phase processes (eg, plasma cleaning). Tribological investigations show that NaOH(aq)‐treated surfaces show reduced friction and wear, relative to the “as‐received” galvanized steel. This is ascribed to carbonate (present as an impurity in NaOH) that adsorbs to the surface of the substrate during NaOH(aq) immersion. Carbonate removal through sonication in water generates surfaces that show friction similar to “as‐received” galvanized steel. This work is useful in areas (eg, automotive manufacturing), where the effective removal of lubricants following tribological contact is key to subsequent paint adhesion.

“…In the second case, grafting can occur directly on oxide layer. This mainly concerns organic acids such as phosphonic [8,9], carboxylic [10,11], or sulfonic [12] acids which can be grafted on aluminum [13][14][15], titanium [8,9,16], copper [17] or stainless steel [10,11,18] surfaces. These systems are increasingly studied as they offer the attractive possibility to work directly on oxidized surfaces without any previous treatments.…”

“…Interest in self-assembled alkylphosphonic acid on metal substrates has grown for the past years. Grafting on nickel [19,20], cobalt chromium alloy [21], copper [17,22], alumina [23], stainless steel [18] has already been carried out. Nevertheless, to the best of our knowledge, no study has been carried out yet on the effects of alkyl chain length and modification time on selfassembly of alkylphosphonic acids on stainless steel.…”

Self-assembly of alkylphosphonic acids on stainless steel was investigated under different conditions. Four different alkylphosphonic acids exhibiting alkyl chain of various size were synthesized and studied: butylphosphonic acid (C4P), octylphosphonic acid (C8P), decylphosphonic acid (C10P), and hexadecylphosphonic acid (C16P). Electrochemistry experiments were extensively carried out in order to determine electrochemical surface blocking of adsorbed layers in function of grafting time. In term of surface blocking, an 8h modification time was optimal for all alkylphosphonic acids. Longer immersion times lead to degradation of adsorbed layers. For the first time, grafting of C16P was studied under high frequency ultrasound irradiation. Interestingly, grafting process is highly accelerated under sonication and well-covering C16P modified substrates are obtained after 1h of immersion under ultrasound irradiation. This would allow to elaborate high-quality alkylphosphonic acids modified samples within much shorter times. Water contact angles measurements and X-ray Photoelectrons Spectroscopy (XPS) confirmed presence of adsorbed alkylphosphonic acids on stainless steel surface. A very tight link between electrochemical blocking, surface hydrophobicity and species chemical grafting was established.
