摘要：

In this study, the intricate interplay among surface conditions, friction, and sealing behavior was investigated using a simplified omega seal as a representative model. The effects of surface conditions were examined by preparing samples with a thin coating on one set, which were then compared to uncoated reference samples. Subsequently, the impact arising from surface differences was analyzed. Findings emphasize the critical importance of surfaces characterized by a low coefficient of friction, underlining the necessity for long-term preservation. This investigation revealed a compelling link between the stick-slip phenomenon and the topo-graphical features of the friction interface. These insights not only underscore the essential nature of tailored surface treatments but also their pivotal role in optimizing the performance of rubber seals.
