The objective of this study is to replace steel-phosphating treatments with selfassembled monolayers (SAMs), in this case, of phosphonic acids. Two industrial applications are targeted:-Obtaining an adhesion primer between steel and paint or lubricating stainless steel for mechanical applications, such as stamping.-Research has been conducted using alkyl phosphonic acids. The carbon chain length and terminal function are changed to obtain the best properties depending on the application.

“…Effective minimization of corrosion becomes an important task as it can compensate to a certain extent the huge economic loss and structural failures in the industries, which are the protuberant consequences of corrosion. The strategies such as cathodic protection, use of protective coatings [ 1 , 2 , 3 , 4 , 5 ] and corrosion-inhibitors [ 6 , 7 , 8 ] are employed which may alter the mechanism and/or slow down the rate of corrosion from the metallic surfaces.…”

Effective inhibition of metallic corrosion to prevent its consequent loss is one of the serious apprehensions for industries in the modern world. This paper analyses the application of poly(2-ethyl-2-oxazoline) (PEOX) as an effective inhibitor of corrosion, when it is made to be in contact with the surfaces of mild steel (MS). The sustainability of MS against corrosion in 0.1 M Hydrochloric acid solution in the presence of known concentration of PEOX is assessed by potentiodynamic polarization (PDP) measurements, linear polarization studies (LPR), and electrochemical impedance spectroscopy (EIS). It was observed that PEOX behaves as better inhibitor for mild steel corrosion in 0.1 M HCl solution and it show enhanced inhibition efficiency (IE%) 79% at a concentration of 50 ppm. The polarization experiments indicated that addition of PEOX in concentrations varies from 25 ppm to 50 ppm induces a decrease of both cathodic and anodic currents densities. Also, the micrographs recorded by the Scanning Electron Microscopy confirm that molecules of PEOX act as corrosion inhibitors for the surfaces of MS in 0.1 M HCl. The stability of the MS surface in a corrosion-prone environment is traced by measuring the contact angles of water droplets placed on the MS surface, to quantify the extent of deterioration, if any, due to corrosion. The results presented here show that the compound PEOX performs as a mixed-type inhibitor against corrosion at the MS surface in acidic medium. Theoretical studies based on the electronic structure of PEOX in aqueous medium also support its performance as a successful corrosion-inhibitor.

“…Metallic corrosion leads to increased structural failures and huge economic losses in various industries. Different coating approaches have been studied in the past for corrosion protection, including ceramic coatings, − polymer coatings, − electrodeposition of nanocrystalline materials, − and self-assembled nanocoatings. − In addition to these techniques, a combination of above-mentioned methods, such as coatings using nanopaints, which contain nanomaterials in polymer paints, and multiphase nanomaterial-based coatings that can withstand high temperature, have also been tested. , Recent studies indicate that nanomaterials, because of their high surface area and high adhesion to substrates, provide effective corrosion resistance and can be used for protective coatings on various surfaces. , …”

Recently, two-dimensional, layered materials such as graphene and hexagonal boron nitride (h-BN) have been identified as interesting materials for a range of applications. Here, we demonstrate the corrosion prevention applications of h-BN in marine coatings. The performance of h-BN/polymer hybrid coatings, applied on stainless steel, were evaluated using electrochemical techniques in simulated seawater media [marine media]. h-BN/polymer coating shows an efficient corrosion protection with a low corrosion current density of 5.14 × 10(-8) A/cm(2) and corrosion rate of 1.19 × 10(-3) mm/year and it is attributed to the hydrofobic, inert and dielectric nature of boron nitride. The results indicated that the stainless steel with coatings exhibited improved corrosion resistance. Electrochemical impedance spectroscopy and potentiodynamic analysis were used to propose a mechanism for the increased corrosion resistance of h-BN coatings.
