摩擦化学膜的成因与结构:矿物质化学和有机质化学观点

Views of Mineralogical and Organics Chemistry on Origin and Structure of Tribochemical Films

减摩剂、抗磨剂、极压剂与修复剂共同构成在摩擦学意义上更完善的摩擦学添加剂系列。摩擦化学膜是摩擦学添加剂在摩擦表面热/应力场中参与生成的无机物种和有机物种的共生体,无机物种构成润滑膜骨架,有机物种或简单无机质点以吸附状态或以间隙化合物形式依附于或弥散于骨架构造中,共同提供摩擦化学膜的全部润滑功效———减摩、抗磨、极压效应和修复功能。应用矿物质化学和有机质化学观点诠释摩擦化学膜的成因与结构特性,特别是基于应力化学原理比较分析岩石物理和地球化学过程中的成岩和生油现象与摩擦化学过程中的润滑效应,提出摩擦成岩与生油化学研究,摩擦化学场中的成岩和生油效应及其摩擦学意义,以及开发基于自然物质和过程的工业摩擦学应用技术。

Friction modifiers,antiwear & extreme pressure additives,and wear reconditioners consist of the more complete triboadditive series in the tribological sense,and they are chemically involved in the tribochemical reactions on tribosurfaces in the presence of thermal / stress fields and generate tribochemical films that are symbiotic third bodies composed of inorganic and organic species.The inorganic species construct the skeleton structures of the lubricious films with the organic species and simpler inorganic species adhering on or dispersing in the bulk structure in the state of adsorption or in the form of interstitial compounds,offering the whole wavelength of effectiveness of the tribochemical films—friction reduction,wear abatement,extreme-pressure and were reconditioning.The genesis and structure of tribochemical films were explained with viewpoints of minerals chemistry and organics chemistry.Specifically,considering the unique role played by stress chemistry in processes in rock physics,geochemistry and tribochemistry,an analogy analysis was made between the rock formation and oil genesis in rock physics and geochemistry and the boundary lubrication effect in tribochemistry. An interdisciplinary subject of chemistry was suggested of the tribo-induced rock formation and oil genesis.The endeavor is oriented to explore the effects of rock formation and oil genesis that are potential in the tribochemical field and their tribological implications,and to develop industrially significant tribological technologies well based on natural substances and processes.
