Wear Particle Formation Mechanisms.

摘要: Abstract : A lightly loaded, room temperature, lubricated bronze on steel sliding system was studied to determine the mechanisms of wear debris formation. Examination surfaces carried out with both optical and scanning electron microscopes. The lubricating oil processed through a Ferrograph Analyzer remove particles so that they could be examined. It found were capable high degree strain during contact. surface caused by repeated contact allowed for nucleation progressive propagation sub-surface cracks, produce particles. Cross-sections showed cracks nucleating at voids which had become elongated due gradient. Material transferred from one another appeared aid in smoothening process. Large pieces (20 micrometers over) made up many smaller became compacted (Modified author abstract)
