Optimisation of a chuck for cardboard can seaming – part 1: surface engineering and tribological evaluation

Igor Velkavrh, Florian Ausserer, Stefan Klien, Joel Voyer, Georg Vorlaufer, Alexander Abbrederis

During the production of cardboard food cans, the packaging bottom and the cylindrical wall are joined in the seaming process. In order to achieve a high-quality, crack-free…

Optimisation of a chuck for cardboard can seaming – part 2: numerical modelling and statistical analyses

Igor Velkavrh, Florian Ausserer, Stefan Klien, Joel Voyer, Georg Vorlaufer, Alexander Abbrederis

In the cardboard package production process, the cardboard roll and the cardboard bottom are joined in the seaming process. During the process, the cardboard is plastically…

Laser interference patterned ta-C-coated dry forming tools

Theresa Jähnig, Andrés F. Lasagni

This study aims to introduce a strategy that permits well-defined contact areas in forming tools for improving both wear and friction properties by a selective laser treatment of…

Modeling tool wear in titanium cutting with an in-process tribometer

Linus Meier, Michael Eglin

Metalworking fluids can significantly increase the tool life in titanium cutting, however, full-scale cutting tests to determine the performance of metalworking fluid are…

ToF-SIMS analysis of boundary layers formed under zinc-free antiwear

Dennis Mallach, Florian Pape, Dieter Lipinsky, Heinrich F. Arlinghaus

The structure and chemical composition of boundary layers built under tribological stress affect the friction and wear of solid-state surfaces in a major way. Therefore…

Synergistic effects of antiwear and friction modifier additives

Jennifer Eickworth, Enes Aydin, Martin Dienwiebel, Thomas Rühle, Patrick Wilke, Tobias Reinhard Umbach

Interactions of different additive types for antiwear/friction modification on surfaces can be synergistic or antagonistic in nature. This paper aims to investigate whether there…

A tribometer and methodology for wear and friction testing of porous journal bearings at elevated temperatures

Christian Dejan Ielchici, Stefan Krenn, Stefan J. Eder

This paper aims on a methodology to overcome the fact that conventional service life testing of porous journal bearings (PJBs) requires long test times and is not economical.

Comparing oil condition in diesel and gasoline engines

Adam Agocs, Serhiy Budnyk, Marcella Frauscher, Bettina Ronai, Charlotte Besser, Nicole Dörr

This paper aims to compare the conditions of in-service oils from diesel and gasoline engines, with focus on nitration.
