Overview

Molecular dynamics analysis reveals friction reduction in FeCrNi due to bismuth inclusions and surface roughness effects.

Key Points

  • This investigation aims to understand how bismuth inclusions and surface roughness affect friction and wear in FeCrNi.
  • Utilized molecular dynamics simulations to analyze frictional behavior
  • Examined the influence of bismuth particles and surface roughness
  • Assessed stress concentration and dislocation movement during friction
  • Friction force decreased significantly due to bismuth's self-lubricating effect
  • Valley positions on the surface exhibited the most severe wear
  • Increased roughness correlates positively with the wear rate of the workpiece
