Understanding the complexities of dry sliding wear behaviour of steels

Abstract

Sliding wear behaviour is a very complex procedure where several parameters, including nature of the two abrading bodies and variables related to the conditions under which the actual experiments were conducted, may influence the final material loss. Disentangling these parameters will improve the understanding and the predictions can be compared with the performance of the existing materials. An attempt was made in the current work to develop a model, considering several material specific variables (e.g. composition, microstructure, hardness, etc.) along with the experimental conditions (load, distance, temperature, etc.). The predictions were quite consistent with existing knowledge. The model was also validated with actual experiments with varying load and distance slid conditions which were never known to the model.
