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.

Anodizing Al–Si Foundry Alloys: A Critical Review

Advanced Engineering Materials, Volume 24, Issue 4, April 2022., 2022
Compared with pure aluminum and wrought aluminum alloys, Al foundry alloys are more difficult to be anodized. This work aims to critically review the main factors influencing the growth and morphology of the anodic layer in Al–Si foundry alloys. In particular, the effects on the oxide thickness, surface mechanical properties, and corrosion resistance ...

Removal of Iron from a Secondary Al–Si Die‐Casting Alloy by Metal Melt Filtration in a Laboratory Filtration Apparatus

Advanced Engineering Materials, Volume 24, Issue 2, February 2022., 2022
The two‐step process reduces the iron content (Fe) after the separation of Fe‐containing intermetallic particles from the residual melt using a specially developed laboratory filtration apparatus. The highest Fe reduction of ≈50% is obtained at 620 °C, whereas the elements Mn and Cr decrease by ≈66% and 86% after metal melt filtration. The influence of
