متن کاملThe surface and tribological chemistry of chlorine- and sulfur- containing lubricant additives
A model for the operation of chlorinated hydrocarbon extreme-pressure additives is outlined in which the chlorinated hydrocarbon thermally decomposes at the hot (~1000 K) interface forming a chloride + carbon film, which is simultaneously worn from the surface. Assuming that seizure occurs when the chloride film thickness decreases to zero reproduces the experimentally measured seizure load vs....
متن کاملUnderstanding the tribological chemistry of chlorine-, sulfur- and phosphorus-containing additives
It is demonstrated that the surface chemistry of simple-model extreme-pressure lubricant additives, measured in ultrahigh vacuum, corresponds to that measured at higher pressures, where film growth rates are monitored using a microbalance. This chemistry and reaction kinetics are used to explain the extreme-pressure lubrication behavior by successfully modeling the measured seizure load vs. add...
متن کاملSurface Chemistry in Tribology
Introduction In general, the twentieth century marked the first major incursion of chemists into the world of tribology. Driven partly by the need for improved lubricants for new machines developed in the first few decades of the century, and partly by new analytical capabilities, lubricant chemists and tribochemists were to become full partners in the science of tribology. In this review we co...
متن کاملGraphite and Hybrid Nanomaterials as Lubricant Additives
Lubricant additives, based on inorganic nanoparticles coated with organic outer layer, can reduce wear and increase load-carrying capacity of base oil remarkably, indicating the great potential of hybrid nanoparticles as anti-wear and extreme-pressure additives with excellent levels of performance. The organic part in the hybrid materials improves their flexibility and stability, while the inor...
