Overview

Investigation shows the impact of plasma nitriding on wear resistance in engine valves, suggesting improved durability.

Key Points

  • The aim is to evaluate how plasma nitriding affects the wear resistance of valve materials and their bushings.
  • Comparative assessment of wear resistance in treated and untreated valve materials.
  • Use of 40Cr9Si2 and 55Cr20Mn9NNi4 steel compositions for testing.
  • Evaluation of wear resistance for both valve stems and bushings.
  • Plasma nitriding improved wear resistance compared to untreated surfaces.
  • Chemical composition significantly influenced wear properties of the steels.
  • Combined assessment of valves and bushings showed notable wear reduction.
