Development of Calcium‐Based Coatings to Mitigate Vanadate Corrosion

open access: yesMaterials and Corrosion, EarlyView.
Ca‐rich coatings can suppress the corrosive attack of molten V2O5 by forming Ca2 V2 O7 and Ca V2 O6. For this, a large Ca‐reservoir is key to mitigate corrosion at 600°C and 700°C. ABSTRACT Vanadate corrosion occurs in devices powered by heavy fuel oil, such as stationary turbines.

Hot Corrosion Type X: Behavior of Mo‐Si‐B at Different Temperatures

open access: yesMaterials and Corrosion, EarlyView.
The temperature‐dependent mechanism for Mo‐Si‐B is investigated by studying the hot corrosion resistance of Mo‐Si‐B at 500°C–900°C. Post‐testing analysis via XRD, SEM, Raman and EPMA is used to reveal the degradation mechanisms. Na2MoO4, which forms under Na2SO4 deposits, is responsible for dissolving the surrounding material due to its lower melting ...

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

open access: yesMaterials 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

Analysis of Mechanical‐Electrical‐Hydraulic Coupled Vibration Response Characteristics of Thermal Control Circulating Pumps Supported by Water‐Lubricated Bearings

open access: yesInternational Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT The operational reliability of thermal control circulation pumps is significantly restricted by the multi‐physics coupled environment. To reveal the vibration transmission mechanisms and dynamic response characteristics under multi‐field coupled excitations, a multi‐DOF coupled dynamic representation of the overall system, incorporating the ...

Improving enteral nutrition in patients requiring neurological intensive care unit care: A retrospective study on a novel bedside nasointestinal tube placement technique

open access: yesNutrition in Clinical Practice, EarlyView.
Abstract Background This study aimed to develop and assess a bedside nasojejunal tube placement technique designed for resource‐limited settings to address the specific challenges of enteral nutrition (EN) delivery in neurocritical care patients, particularly those at high risk of reflux and aspiration. The technique sought to overcome the drawbacks of
