Research and Development on Coatings and Paints for Geothermal Environments: A Review
Advanced Materials Technologies, Volume 8, Issue 18, September 25, 2023., 2023 Geothermal power production, by harnessing the natural heat in the earth's crust, provides clean energy, with year‐round availability. However, corrosion, erosion, and scaling of power plant components can hinder energy production. In his review paper, the first of its kind since 1980, a detailed overview of research studies on coatings developed to ...

Materials and Corrosion, Volume 74, Issue 8, Page 1148-1158, August 2023., 2023 Zinc flake coatings are compared using spectroelectrochemistry, accelerated corrosion and outdoor weathering tests. Chloride concentration, and its effect on the passive oxide, appears key to moderating the sacrificial zinc dissolution rate. We gained insight into the influence of the environment and zinc flake (alloy) used, paving the way for tailored

Oxygen‐Free Production—From Vision to Application
Advanced Engineering Materials, Volume 25, Issue 12, June 2023., 2023 Extremely low oxygen partial pressures can be obtained by adding small amounts of monosilane to an inert gas environment. The effects of such an environment on various production processes such as milling, compound casting, and thermal spraying are analyzed.

Glucamines as green alternatives to conventional amino alcohols in metalworking fluids
Materials and Corrosion, Volume 74, Issue 3, Page 394-402, March 2023., 2023 This paper describes the scalable synthesis of N,N‐diethylglucamine (DEGA) from glucose and diethylamine in one step and its evaluation as an alkaline additive to common acidic corrosion inhibitors. Electrochemical measurements and flame atomic absorption spectroscopy revealed good anticorrosive properties and low leaching of important alloying metals ...

High‐Order Fiber Bragg Grating Corrosion Sensor Based on the Detection of a Local Surface Expansion
Structural Control and Health Monitoring, Volume 2023, Issue 1, 2023., 2023 This paper presents a fiber optic sensor for the detection of corrosion processes that occur on metal surfaces. In the proposed sensor design, a sensing fiber with an inscribed high‐order Bragg grating is attached to the observed metal surface. A broadening of high‐order Bragg grating spectral characteristics is observed and used to detect small and ...

Structural factors influence on strength properties of S235JR steel welded joints
Journal of Physics: Conference Series, 2021 Abstract The paper presents the results of strength tests of welded joints of S235JR structural steel. Welded joints of various geometries were made: butt joints, overlap joints with a single weld, overlap joints with double welds, overlap joints with spot welds, overlap joints with hole welds, and double-flanged seam. The strength tests

Extracting true stresses and strains from nominal stresses and strains in tensile testing
Strain, Volume 57, Issue 6, December 2021., 2021 Abstract Seemingly a simple task, the extraction of the flow curve (true stress vs. true plastic strain) from nominal stresses and strains in standard tensile testing still has its unsolved points. This study addresses two of them: (i) in materials without yield point phenomenon (or generally in the region of homogeneous plastic deformation), the true ...
