“…However, limiting current can be clearly seen m presence of ammo aCids, whereas high IS was noticed unambiguously without addition of aminoacids. Solution contains amino acid involve electrostatic interaction on the metal surface [5] enhance metal (Ni, Cr, Fe) -cysteine complex, which protect the metal surface from electron transfer from metal surface [13] to bulk solution (electrolyte) was restri cted. Nanostructured TiN, Ti02 single layer, TiN/Ti02 multi layer were successfully prepared using reactive direct current (DC) magnetron sputtering onto 316L SS substrates.…”

“…Moreover, multi layer coatings such as TiN/Ti2N and TiN/TiAlN exhibited new possibilities for several applications including non toxic, biocompatible [3], superior hardness and high oxidation resistance [4]. It has been well established that amino acids play an important role in body solution and suppress the susceptibility of metal implant corrosion [5][6]. Glutamine is an amino acid, just like a protein.…”

Single and multi layer TiN, Ti02 thin films were deposited by DC magnetron sputtering technique using a mixture of Ar as sputtering gas 02' N2 as a reactive gases. The hard coatings deposited by PVD methods can have different phases and grain structures which is generally composed of columnar crystals from the transition layer to the coating surfaces. Results from the electrochemical polarization and impedance studies showed the favorable behavior of the TiN, which have improved the corrosion resistance property followed by TiN/Ti02 multilayer, Ti02 and uncoated 316L SS in presence of artificial blood plasma with and without addition of amino acids.Hemocompatibility was performed to analyze the materials biocompatibility. Coated thin films showed better compatibility than uncoated films. Ti02 exhibited highly hydrophilic in nature than other films. These nanostructure coatings were confirmed by XRD and AFM.

“…Generally, these compounds act on the corrosion process by adsorption on the metal surface, forming a protective film and blocking the active sites. The adsorption mechanism of the inhibitor molecules plays a very important role because the degree of protection of the metal or alloy depends on the adsorption process . The inhibiting properties of l ‐histidine in the corrosion process of carbon steel in corrosive solutions containing sodium acetate has been investigated …”

Complexes of cobalt(II), nickel(II) and copper(II) of l‐histidine Schiff base derived from 2,4‐dihydroxybenzaldehyde and 2‐hydroxy‐1‐naphthaldehyde have been synthesized. The structures of ligands and complexes have been characterized using elemental analysis, molar conductance, magnetic moment measurements, and spectral and thermal studies. The ligands behave as tridentate, coordinating through the azomethine nitrogen and α‐hydroxyl and carboxylic oxygen atoms. The obtained results show that the Cu(II) complexes have square planar geometry, the Co(II) complexes have octahedral and tetrahedral geometries and the Ni(II) complexes have square planar and octahedral geometries. The molecular geometries of the metal complexes are supported by three‐dimensional molecular modelling using molecular mechanics (MM+) and semiempirical molecular orbital calculations (PM3). The inhibition effect of ligands and complexes on the corrosion of aluminium in 2 M H2SO4 was investigated using weight loss. The inhibition efficiency is found to increase with increasing inhibitor concentration and temperature. The increase in inhibition efficiency with increasing temperature is suggestive of a chemical adsorption process. Copyright © 2014 John Wiley & Sons, Ltd.
