Friction units of modern power turbines require the use of special materials with stable and low coefficients of friction under extreme conditions. Antifriction carbon-graphite materials, in particular isotropic pyrolytic carbon, are most successfully used for these purposes. Isotropic pyrolytic carbon was found to have a lower friction coefficient and wear rate than ATG-S antifriction graphite. The difference in the tribological behavior of materials was proposed to be caused by various destruction mechanisms based on an analysis of the microstructure and fractograms of wear traces. Also, isotropic pyrolytic carbon was shown to decrease the wear rate and friction coefficient with increasing density.

高速测试中热解碳的摩擦学特性

现代动力涡轮机的摩擦装置需要使用在极端条件下具有稳定且低摩擦系数的特殊材料。减摩碳石墨材料，特别是各向同性的热解碳，最成功地用于这些目的。发现各向同性的热解碳的摩擦系数和磨损率低于ATG-S减摩石墨。在对磨损痕迹的微观结构和分形图进行分析的基础上，提出了材料的摩擦学性能差异是由多种破坏机理引起的。同样，各向同性的热解碳显示出随着密度增加而降低磨损率和摩擦系数。
