Diamond and ceramic particles are widely regarded as the gold standard for high coefficients of friction, yet frequently necessitate the implementation of additional coatings or inserts. However, specific laser structures that do not require supplementary components offer a novel alternative. The pivotal consideration is the selection of the most appropriate structure to achieve the desired…
In components under cyclic loads contacts, micro-slip movements lead to a local change in the coefficient of friction (coefficient of friction development), knowledge of which is essential for the consideration of numerous effects (fretting fatigue, vibration wear, rolling bearing migration, transmission capability, contact stiffness). In addition, the reserves of the components in the drivetrain are…
At the international conference „24th International Colloquium Tribology“ on the topics of friction, wear, lubricants and tribomechanics, the institute showed up with IKAT-specific research topics. Mr Silvano Oehme presented the latest results of the research project „Simulation of the local CoF development in cyclically loaded clamped contact surfaces (fretting)“. With a combined approach of model…
At the 15th VDI Conference on Plain and Roller Bearings, the Plain Bearings group presented a joint project with the Klüber company, which deals with the reduction of failure by fretting fatigue in plain bearings. Here, a thin polymer layer was applied to plain bearings to reduce wear. The advantages of this process were presented…
On 11.10.2018 Mr. Müller defended his thesis and was rewarded for his outstanding performance! The work on the topic „Statistical analysis of a standardised test method for determining static friction values“ was able to validate the usage of the standard normal distribution to the test method as expected on the basis of a large random…
