Towards eliminating friction and wear in plain bearings operating without lubrication.

ABSTRACT: Plain bearings, renowned for their versatility and simplicity, are extensively utilized in engineering design across various industries involving moving parts. Lubrication is vital to the functioning of these bearings, yet their usage is inhibited under dynamic load conditions, or at elevated or reduced temperatures due to this dependency on lubrication. This study introduces an innovative method to significantly mitigate friction and wear in plain bearings operating without lubrication. The plain bearings were constructed from steel-bronze pairs, where the steel shafts were alloyed with bismuth oxide via short-pulse laser treatment. MnO₂ was utilized as a carrier to incorporate the bismuth oxide into the surface layers of the steel. Insights from transmission electron microscop
