Lead-free low friction bronze

This project aims to evaluate the tribological properties and seizure resistance of journal bearings made of various bronze bearing alloys. The industry faces a growing need for more sustainable, lead-free alternatives to replace the widely used leaded bronze alloy.

Background

Lead is commonly used in bronze bearing alloys for machine components due to its exceptional anti-wear and anti-friction properties. However, despite these advantages, lead poses significant risks to human health and the environment. Consequently, the European Union has introduced strict regulations on lead usage, with the potential for a complete ban in the near future. This underscores the urgency of developing new lead-free bronze alloys.

Goal

The primary goal of this project is to design more sustainable, lead-free bronze bearing alloys while enhancing an understanding of how different alloys influence friction, wear, temperature, pressure, and seizure behavior, including the mechanisms underlying these phenomena.
