9313271 Lee The mechanisms of scuffing will be studied. Two possible competing mechanisms are the critical temperature-pressure mechanism of desorption of a lubricant film, aided by frictional heating and abetted by hydrostatic pressure in the contact; and the thermomechanical wear mechanism, in which thermal heating causes plastic flow of the contacting asperity. A set of experiments will be performed to determine the relative roles of these mechanisms and the conditions under which they operate. ***

9313271 Lee将研究擦伤的机制。 两种可能的竞争机制是润滑剂膜的解吸的临界温度-压力机制，由摩擦加热辅助并由接触中的静水压力教唆;和热机械磨损机制，其中热加热导致接触粗糙的塑性流动。 将进行一系列实验，以确定这些机制的相对作用及其运作条件。 ***
