Abstract:
Mechanical wear is a tribological phenomenon that causes parts deterioration over time when they are in service. The wear causes enormous performance and economic burden on the mechanical applications, and the main aspects of mechanical designs should consider first. Mechanical wear is accelerated in the presence of high temperature that is caused by the frictional forces between the sliding surfaces. The generated temperature is classified into instantaneous (flash) and bulk. Both flash and bulk temperatures are modeled mathematically and verified experimentally. The models utilize different techniques and simplifications in order to obtain valid results. Future directions of the modeling techniques involve enhancing the collection of the experimental data as well as the incorporation of the chemical interactions.
