, 2010 In this paper, a model is generated of the effect of temperature on the erosion-corrosion of Fe in aqueous conditions, for room temperature to 373K. The results indicate how the transition from active to passivation dominated regimes for Fe are favoured ...

Karl Popper and the Mechanisms of Hydrogen Embrittlement
Advanced Engineering Materials, EarlyView.Representation of the beginning of loss of ductility rather than embrittlement. Small concentrations of hydrogen in a diffusible form within iron are well‐established to harm the mechanical integrity of steels. There are theories that attempt to explain the pernicious role of hydrogen.

Advanced Engineering Materials, EarlyView.The present study investigates recycling of NiTi shape memory alloys via vacuum induction melting. An ingot was synthesized from elemental Ni and Ti and subjected to three subsequent remelting cycles. Remelting increases process durations and impurity levels and adversely affects microstructures and functional properties.

Current Status and Challenges in Data Collection for Aerospace Coatings Deposited by Plasma Spraying
Advanced Engineering Materials, EarlyView.An innovative approach has been integrated into the GRENAT project to optimize plasma spraying and coating performance. Raw materials are accelerated and melted in the plasma generated by torches, creating coatings. Monitoring sensors collect process data which are combined with ex situ characterization data.

CO2 Corrosion in the Region Between the Static and Turbulent Flow Regimes [PDF]
Materials Research, 2015 This paper discusses the influence of the flow of a fluid from the static regime to the turbulent in CO2 corrosion experienced by low carbon steel. A more comprehensive approach to CO2 corrosion implies taking the free flowing velocity and shear stress ...

Erosion-corrosion behavior of L80 steel under high velocity wet gas condition by flow loop method
工程科学学报, 2018 With the continuous petroleum extraction from deep-water subsea gas fields, many long distance offshore natural gas pipelines have been constructed. The design parameters directly affect the gas flow velocity in pipelines, which may introduce high wall ...

Erosion Corrosion Behavior of Aluminum Electrode in Simulated HVDC Water Cooling at 50 °C
International Journal of Electrochemical Science, 2020 The inner wall of aluminum radiators in a high voltage direct current (HVDC) thyristor valve cooling systems are corroded under a continuous erosion of water coolant at ~50 °C, and the dissolved aluminum ions precipitate again on the surface of the ...
