Surface Ventures Mini-Symposium - Electrification impact on brake applications
Ensuring dependable braking performance in EVs
Regenerative braking and reduced pad use shift friction and wear behavior and can increase corrosion risks, so legacy test routines often miss critical effects. Effective test methods must combine mechanical, thermal, and electrical factors to isolate true material and lubricant responses. This symposium gathers experts in the field of tribology of EVs to present research data, discuss instrumented solutions, and answer questions.
Watch this Surface Ventures webinar to learn how:
- Innovative solutions and testing protocols can address environmental and corrosion challenges
- WLTP-based testing protocols are implemented in lab-scale tribometers to screen brake materials for particulate emissions
- Friction and PM10 emissions differ between GCI and coated rotors, and why new friction material formulations are needed for coated rotors
- Lab-scale testing bridges the gap between material development and dynamometer testing for advanced understanding of brake materials
