Rolling contact fatigue of nitrided 32CrMoV13 steel

Résumé

In this paper, dent initiated Rolling Contact Fatigue (RCF) of nitrided 32CrMoV13 steel is studied, both experimentally and numerically, from the indentation process to the RCF failure. First, a method based on nano-indentation testing has been set up to identify the local elastic-plastic behaviour of nitrided 32CrMoV13 steel, hence enabling the characterisation of the micro-yield shear stress profile. Fatigue tests have then been conducted to evidence the influence of different operating conditions on RCF and to compare nitrided 32CrMoV13 steel to a reference material. Last, a numerical study is presented. An indent based endurance limit, H1I is determined. The comparison of H1I with experimental results show that it is a coherent definition of the endurance limit.
