The Technology of Structural-Energy Adaptation as a Factor in Increasing Operational Characteristics
摘要
The relationship between wear and tear resistance, microgeometry, surface reflectivity, and the uniformity of the facial layer has been studied. The results of assessing the facial layer condition of samples after friction using the continuous denting and scanning method are presented. The wear and tear of tribocoupling parts at negative temperatures (−50 °C) under conditions of one-component loading (slip), two-component (impact followed by slipping), and three-component (impact and slipping in two mutually perpendicular directions) on a special test unit is considered. A connection is noted between the tribological joints’ wear and tear resistance and the facial layer’s structural homogeneity. The principle of tribosystems wear and tear resistance is proposed using principles of structural and energy adjustment of material during friction under various loading types. The prospects for machining a polished surface with low roughness and high reflectivity by forming a certain structural condition of the facial layer are presented. The possibility of controlling parts’ operational characteristics by varying the manufacturing and operating conditions, considering the formation of the facial layer features, is shown.
