Analysis of Wettability and Contact Angle Hysteresis on a Thermally Treated Low Free Energy Surface

The biomimetic replication of the lotus leaf to create hierarchical surface morphology has attracted significant research interest due to its potential applications in self-cleaning, anti-corrosion, anti-fouling, and anti-icing surfaces. Several attempts have been made to create such structure using metal-fatty acid co...

Optimization of friction, wear and temperature in graphite-reinforced PTFE/bronze composite bearings using Taguchi analysis

This study aims to develop and optimize a self-lubricating porous plain bearing system fabricated through powder metallurgy and surface spray coating of polytetrafluoroethylene (PTFE) and graphite-reinforced PTFE composites. The research focuses on minimizing friction coefficient, wear loss and bearing operating te...
