Tribo oxydation
WebAs is shown in Figure 2, the addition of material transferred from the workpiece along with further tribo-oxidation results in a small, but well-defined and sharp peak at 420 cm −1 associated with the formation and/or promotion in the surface of Al 2 O 3 (Spectrum 3) due to tribo-oxidation of the tool surface. WebDec 22, 2024 · Abstract. Oxidative mechanisms in tribological processes are commonly related with temperature and the real contact area. In this article, a lumped parameter dynamic model was developed to predict friction-generated oxide thicknesses in dry sliding conditions. The proposed model is based on conservative principles and causal equations …
