From Damage to Functionality: Remanufacturing of Thrust Roller Bearings by Tailored Forming

open access: yesAdvanced Engineering Materials, Volume 27, Issue 16, August 2025.
Herein, the wear and fatigue behavior of repaired bearing raceways with a new powder alloy is investigated using a FE8 test‐rig and an oscillating tribometer. The tests are compared with industrial manufactured bearings to evaluate the repair quality. The repair can extend the service life of the repaired bearing to that of a new bearing and improves ...

Occupationally Relevant Zinc‐ and Copper‐Containing Metal Fumes Inhibit Human THP‐1 Macrophage TNF and IL‐6 Responses to Bacterial Stimuli

open access: yesGlobal Challenges, Volume 9, Issue 5, May 2025.
Metal workers have an increased risk of severe pneumonia due to metal fume exposure. In this study, zinc oxide (ZnO) and copper oxide (CuO) particles are found to inhibit specific anti‐bacterial macrophage responses, which may substantially contribute to impaired lung immunity.

Time–Frequency Feature Extraction of Acoustic Emission Signals in Aluminum Alloy MIG Welding Process Based on SST and PCA

open access: yesIEEE Access, 2019
The acoustic emission (AE) signal is weak due to the coupling and intersecting coexistence of other disturbance components in aluminum alloy metal inert-gas welding (MIG) process.

Radial Deposition for Mechanical Bonding of Dissimilar Metals in Wire Arc Additive Manufacturing

open access: yesAdvanced Engineering Materials, Volume 27, Issue 7, April 2025.
Concentric radial deposition patterns are used in a wire‐arc directed energy deposition system to produce a layer‐by‐layer in situ bimetallic coupling between AA5356 and SS308L. The additively generated mechanical bond is produced by residual pressure, created by different thermal expansion coefficients between the concentric material bands during ...

Comparative Fatigue Analysis of Structural Steels Considering Welding and Surface Effects

open access: yesStrain, Volume 61, Issue 2, April 2025.
ABSTRACT There are limited data on the very high‐cycle fatigue for structural steel welds for over 10 million cycles. The purpose of this research is a fatigue performance comparison of the welds made of steels S355JR+AR and S275JR+AR. The goal of reaching the gigacycle fatigue domain is achieved using the ultrasonic fatigue testing at 20 kHz.

An investigation on plasma-MIG hybrid welding process of thick plate aluminum

open access: yesJournal of Advanced Joining Processes
Plasma-Metal Inert Gas (MIG) hybrid welding was employed to carry out bead on plate welding of an aluminum alloy A5052. The plasma arc was ignited to form a keyhole, and a series of welding systems were developed starting with MIG welding. The convective
