Abstract This article is part of a series of articles on the mechanism of tribocatalytic processes. The aim of this study was to analyze the behavior of lubricants containing zinc dialkyldithiophosphate (ZDDP) and ordered molecular structures such as carbon nanotubes (CNTs), fullerenes (C60) and antistatic additive (ASA). The mechanism of lubricant additives has been studied for many years and has been described in numerous publications, including [11,12,30,31]. Two types of tribological tests were used: the high frequency reciprocating rig (HFRR) test and the triboelectric (TET) test, with the latter developed at the Air Force Institute of Technology. It was found that the effectiveness of the lubricating additive (ZDDP) depended on the presence of ordered molecular structures, which were able to conduct energy from the surface of the specimen to the ZDDP reaction zones inside the boundary lubricating film. CNTs and ASA were reported to conduct energy effectively. Fullerenes (C60), on the other hand, were not suitable as energy conductors in the lubrication process.

有序碳结构对摩擦催化机理的影响

摘要 本文是关于摩擦催化过程机理的系列文章的一部分。本研究的目的是分析含有二烷基二硫代磷酸锌 (ZDDP) 和有序分子结构如碳纳米管 (CNT)、富勒烯 (C60) 和抗静电添加剂 (ASA) 的润滑剂的行为。润滑剂添加剂的机理已经研究了很多年，并在许多出版物中有所描述，包括 [11,12,30,31]。使用了两种类型的摩擦学测试：高频往复装置 (HFRR) 测试和摩擦电 (TET) 测试，后者由空军技术学院开发。发现润滑添加剂 (ZDDP) 的有效性取决于有序分子结构的存在，能够将能量从样品表面传导到边界润滑膜内的 ZDDP 反应区。据报道，碳纳米管和 ASA 可以有效地传导能量。另一方面，富勒烯 (C60) 不适合作为润滑过程中的能量导体。
