Neodymium-decorated graphene oxide as a corrosion barrier layer on Ti6Al4V alloy in acidic medium

Abstract

Neodymium-decorated graphene oxide is chemisorbed by non-bonding electrons on Ti6Al4V surface increasing the corrosion inhibition in acidic media.

Experimental and computational studies of graphene oxide covalently functionalized by octylamine: electrochemical stability, hydrogen evolution, and corrosion inhibition of the AZ13 Mg alloy in 3.5% NaCl

“…The impedance studies were carried out from 0.01 mHz to 100 kHz by a 920D CHI electrochemical workstation. The corrosion inhibition efficiency was evaluated by the following eqn (1) and (2). Hence the octylamine functionalized graphene oxide redox stability was studied by three cell electrochemical system, and working electrode was used platinum disk electrode.…”

“…1 The nanoparticle-incorporated graphene oxide behaved as a corrosion inhibition barrier on the mild steel alloy surface in an acidic medium. 2,3 Furthermore, phenylenediaminefunctionalized graphene oxide acted as a corrosion barrier layer on the copper surface. 4 Virtanen discussed the biological importance of the Mg alloy and its interaction with the body and its uids.…”

Experimental and computational studies of a graphene oxide barrier layer covalently functionalized with amino acids on Mg AZ13 alloy in salt medium

“…AZ13 mg alloy was cut into 1 cm  1 cm pieces and polished with series of silicon paper from 400 to 1200 micron. 9 The polished Mg alloys were washed with acetone and water before coating. The (GO + L) and epoxy powder were mixed in 2 : 1 ratio with binder (polyamine), the coating was done by brush method and brush size was 0.2 micron.…”

“…7 The authors reported that silane modied coated AZ31 magnesium alloy corrosion resistance increased in articial body uids due to the silane acting as self-healing agent. Further, alanine, glycine, and leucine amino acids were shown to work as corrosion inhibitors on mild steel in the 1 M HCl medium, [8][9][10][11][12] and with increased amount of the inhibitor corrosion inhibition efficiency increased. Furthermore, the cerium decorated GO and GO coated Mg alloy were treated in 3.5% NaCl medium.…”

Microstructure, nano-mechanical characterization, and fretting wear behavior of plasma surface Cr-Nb alloying on γ-TiAl

“…TiAl alloy has shown the promising application prospect in the manufacturing of high thrust-to-weight ratio aircraft engines due to its lower density and higher elastic modulus than nickel-base superalloy [1][2][3]. Some researches even called TiAl alloy as the new generation of high-temperature structural materials to replace nickel-base superalloy [4,5]. It was reported that GEAE has applied TiAl alloy blades in the GE90 engine, reducing the weight by 200~300 kg.…”
