Investigation of galling mechanisms of 316L stainless steel using finite element method
Résumé
Galling, defined as a severe kind of adhesive wear encountered when friction occurs between two sliding surfaces under sufficient load, is a complex multiscale and multi-physics phenomenon still not thoroughly understood. Its initiation and propagation is impacted by different factors related to microstructure, surface defects or chemical composition. Currently, a normalized galling test, denoted ASTM G-98, can be used to determine experimentally a threshold galling stress of material couples. A finite element modeling, using ABAQUS, of this tribological test is purposed in order to investigate the mechanisms appearing during galling of 316L stainless steel in particular.
