Electrical Contacts and Engineered Plastics: Advanced Tribology Testing with UMT TriboLab
Advanced tribology testing for next-generation materials
This webinar will demonstrate how UMT TriboLab enables electromechanical characterization of dielectric contacts and tribological testing of engineered plastics. Presenters will discuss test configuration, load and motion control, and strategies to replicate real-world operating environments.
Attendees will learn how to:
- Measure electronic contact impedance during AC-electrified tribological tests
- Evaluate electrostatic charging and discharging in dielectric contacts
- Assess friction and wear of thrust washers made from engineered plastics
Webinar Summary
This webinar will feature two presentations that cover the use of Bruker’s UMT TriboLab for advanced electromechanical and tribological characterization. The first part focuses on electrical measurements during tribological testing, including contact impedance under AC electrification and electrostatic charging and discharging in dielectric contacts. The second part highlights testing methodologies for thrust washers made from advanced engineered plastics, with an emphasis on friction, wear, and performance under controlled conditions. Together, these approaches demonstrate how UMT TriboLab enables comprehensive evaluation of next-generation materials across demanding applications.
Tribology, Electricity, and the UMT TriboLab
This talk will cover the utilization of Bruker’s UMT TriboLab for a wide range of electromechanical characterization procedures, from electronic contact impedance measurements during AC-electrified tribological tests, to the measurement of electrostatic charging and discharging in dielectric contacts.
Tribological Evaluation of Advanced Plastics for Thrust Washer Applications
The growing use of advanced plastics in demanding applications is driving the need for reliable tribological evaluation methods. This talk focuses on testing approaches for thrust washers made from engineered polymers, emphasizing friction and wear performance under controlled conditions.
