Tribo-films form on surfaces as a result of friction and wear. The wear rate is dependent on the frictional processes, which develop within these tribo-films. Physical-chemical processes with negative entropy production enhance reduction in the wear rate. Such processes intensively develop once self-organization with dissipative structure formation is initiated. This process leads to significant wear rate reduction. Self-organization can only occur after the system loses thermodynamic stability. This article investigates the behavior of entropy production that results in the loss of thermodynamic stability in order to establish the prevalence of friction modes required for self-organization. Tribo-films with dissipative structures form on the friction surface as a consequence of a self-organization process, resulting in an overall wear rate reduction. It has been demonstrated that a tribo-system begins to lose its thermodynamic stability once it reaches the point of maximum entropy production during the running-in stage.
摩擦和磨损会在表面形成摩擦膜。磨损率取决于摩擦过程，而这些过程在这些摩擦膜中发展。具有负熵产生的物理化学过程会提高磨损率的降低。一旦启动形成耗散结构的自组织过程，此类过程就会强烈发展。这个过程会导致磨损率显著降低。自组织只能在系统失去热力学稳定性之后发生。本文研究导致热力学稳定性丧失的熵产生行为，以便确定自组织所需摩擦模式的普遍性。由于自组织过程，在摩擦表面形成具有耗散结构的摩擦膜，从而导致整体磨损率降低。已经证明，摩擦系统在磨合阶段达到最大熵产生点后开始失去其热力学稳定性。
