Bio‐based tannin‐loaded layered double hydroxides in epoxy coatings for smart corrosion protection of steel in underground infrastructure

Deep Underground Science and Engineering, EarlyView.
This study presents a sustainable smart‐coating strategy for protecting underground steel infrastructures from chloride‐induced corrosion. Zinc‐aluminum layered double hydroxides (LDHs) and tannin‐loaded LDHs (LDH–TA) were incorporated into an epoxy matrix to provide both enhanced barrier properties and active, pH‐responsive inhibition.

A Comparative Investigation on the Corrosion Behavior of cast and rolled ZG21 Mg Alloys

International Journal of Electrochemical Science, 2017
ZG21 Mg alloys exhibit excellent deformation ability at room temperature. However, their corrosion behavior lacks sufficient investigation. The relationship between the second phases and micro-galvanic corrosion of ZG21 Mg alloys has been investigated ...

Competitive Cationic Adsorption‐Driven Dynamic Electrostatic Shielding Enables Ultra‐Stable Zn Metal Anodes

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study investigates the dynamic electrostatic shielding effect driven by competitive cation adsorption and its role in stabilizing zinc anodes for aqueous zinc metal batteries. The preferential adsorption of R+ cations, particularly K+, effectively rearranges the inner Helmholtz layer, modulates the electric field distribution, and weakens zinc ...

Hydrogen Analyses of FSW Cu‐OFP Tested Under Creep Conditions in Sulphide Containing Environment

Materials and Corrosion, EarlyView.
Friction stir welded Cu‐OFP exhibits elevated creep rates in sulphide‐containing aqueous environments, with creep increasing as sulphide concentration rises. Hydrogen measurements indicate that sulphide exposure does not increase hydrogen content. ABSTRACT Friction stir welded oxygen‐free phosphorus‐doped copper (FSW Cu‐OFP) is a candidate material for

Bio-tribocorrosion mechanisms in orthopaedic devices : mapping the micro-abrasion-corrosion behaviour of a simulated CoCrMo hip replacement in calf serum solution [PDF]

, 2014
Load bearing implant prostheses such as orthopaedic hip and knee implants may be considered as tribocorrosion systems since the wear processes are a result of combined mechanical and chemical mechanisms.

Acoustic Activity of Intergranular Corrosion Sensitized AISI 304L in Double‐Loop Electrochemical Potentiodynamic Reactivation Test

Materials and Corrosion, EarlyView.
Intergranular corrosion of AISI 304L is analyzed, combining DLEPR test and AE. Slow scan rate polarization reveals time‐shifted and frequency‐dependent acoustic emission in the active region of the DLEPR curve, allowing a separation between passive oxide rupture, intergranular corrosion and pitting. ABSTRACT Intergranular corrosion (IGC) susceptibility
