Formation and evolution of the interfacial structure in Al/steel compound castings during solidification and heat treatment [PDF]

, 2020
In this work, Al7SiMg/steel compound castings were produced through a low-pressure die casting process. All steel inserts were galvanized, where half of them were flux-coated to further improve the wettability and remove interfacial oxide layers during ...

Offshore Weathering Campaign on a North Sea Wind Farm Part One: Corrosivity Categories

Materials and Corrosion, Volume 76, Issue 6, Page 812-821, June 2025.
To optimize the corrosion protection conditions, the corrosiveness of offshore wind turbines must be determined in several necessary areas of the structure. Therefore detailed investigations were done at real structures. ABSTRACT The aim of this study is to investigate the corrosion behavior of materials and coatings in offshore environments, with a ...

Toward an Internet of Things Circular Economy Using Printed Circuits on Reusable Steel Substrates

Advanced Electronic Materials, Volume 11, Issue 5, April 2025.
Herein, the functionalization of steel over large areas with low‐cost insulative intermediate layers as Printed Circuit Boards (PCBs) is presented, enabling an electronics circular economy. The environmental benefits of the approach are evidenced by Life Cycle Assessments, demonstrating an 85% reduction in Global Warming when compared to FR‐4‐based ...

Effect of Surface Pretreatments on the Formation of Zr‐Based Conversion Layers on Zn–Al–Mg Alloy‐Coated Steel

Materials and Corrosion, Volume 76, Issue 4, Page 510-518, April 2025.
This paper investigates Zr‐based conversion coatings on Zn–Mg–Al alloy‐coated steel. Using XPS and LEIS analyses, the study examines Zr‐layer formation after alkaline and acidic pretreatments. Results highlight the effectiveness of strong alkaline pretreatment in achieving a defect‐free, double‐layered Zr‐conversion coating.

Influence of Surface Preparation on the Durability of Repair Coatings for Prepainted Galvanised Steel

Materials and Corrosion, Volume 76, Issue 4, Page 533-541, April 2025.
This work provides information on the performance of repair coatings for damaged prepainted galvanised steel used for building applications. The results highlighted the need for careful surface preparation on the damaged and corroded surface to eliminate surface salts and residues before the application of the repair coat.
