Tannic acid compound as a corrosion inhibitor: film-forming characteristics and corrosion resistance

工程科学学报, 2019
Tannic acid (TA) is widely used to protect metals from corrosion because it is environmentally friendly and inexpensive. However, the single effect of TA used as corrosion inhibitor has been widely investigated and studies focusing on the corrosion ...

Mapping erosion-corrosion of carbon steel in oil exploration conditions : some new approaches to characterizing mechanisms and synergies [PDF]

, 2010
Erosion by solid particles in oil/water slurries is a technologically important area. In such conditions, it is necessary to distinguish between the effects of the sand, aqueous environment, and the oil.

Mitigation of Cracks in High‐Performance Nickel‐Based Superalloys in Powder Bed Fusion Laser Beam of Metals Using a Metal Matrix Composite Approach

Advanced Engineering Materials, EarlyView.
High‐performance nickel‐based superalloys are often not processible in additive manufacturing (AM) due to hot cracking. The findings in this manuscript propose an efficient method to mitigate cracking and enhance mechanical properties of these alloys by producing a metal matrix composite, contributing to the material and process perspective of the AM ...

Influence of Heat Treatment on Microstructure and Mechanical Properties at Elevated Temperatures of Nonweldable Ni‐Based Alloy Printed by Fused Filament Fabrication

Advanced Engineering Materials, EarlyView.
The fused filament‐fabricated MAR‐M247 alloy without hot isostatic pressing shows the lowest porosity of 4%. Heat treatment at 1220 °C produces coarse precipitates and carbides. Specimens heat‐treated at 1220 °C exhibit higher tensile strength (683 MPa) and elongation (10%) at room temperature.

Role of the reversible electrochemical deprotonation of phosphate species in anaerobic biocorrosion of steels [PDF]

, 2007
Sulphate reducing bacteria are known to play a major role in anaerobic microbiological influenced corrosion of steels, but mechanisms behind their influence are still source of debates as certain phenomena remain unexplained.

Laboratory‐Scale Procedure for Evaluating the Flux Efficiency on Melt Cleanliness and Tensile Properties of Recycled Aluminum Alloys

Advanced Engineering Materials, EarlyView.
A laboratory‐scale procedure is developed to evaluate the efficiency of melt‐cleaning and drossing fluxes during aluminium alloy recycling, studying their effects on melt cleanliness and tensile properties of secondary foundry alloys. This work provides a practical tool for foundries and aluminium refiners to assess the efficiency of salt fluxes in ...

Microbiologically influenced corrosion of steel in coastal surface seawater contaminated by crude oil

npj Materials Degradation, 2022
Petroleum-hydrocarbons spilt in surface seawater may pose potential threats to the corrosion of steel infrastructures. We show that crude oil accelerated steel corrosion mainly by accelerating microbiologically influenced corrosion (MIC).

Impact of Various Rotary Friction Welding Process Parameters on the Mechanical Properties of a Steel–Aluminum Joint

Advanced Engineering Materials, EarlyView.
Rotary friction welding of steel E355 and the aluminum alloy EN AW‐6082 can lead to the formation of brittle intermetallic phases. The primary process parameters are varied in order to determine their influence on this intermetallic phase formation and the resulting mechanical properties.

Corrosion Inhibition of Stainless Steel(314L) using Molasses [PDF]

, 2012
The inhibition effect of molasses of varying concentrations (0.2g/L, 0.3g/L, 0.4g/L, 0.5g/L) on the corrosion of austenitic stainless steel (type 316L) in 0.5M tetraoxosulphate(vi )acid (H2SO4), Brine (6% NaCl), seawater (3% NaCl) and freshwater media ...
