Investigation of Action Mechanism of Additives from Mineral Raw Materials
Journal Title: Tribology in Industry - Year 2011, Vol 33, Issue 3
Abstract
The structural changes of friction surfaces and assosiated changes of main tribological characteristics (coefficuient of friction, weight wear) taking place as a result of introduction of additive into the lubricating oil were investigated. It is shown that the mechanism of additive action is based on its specific composition and dispersity. The positive effect of the additive is demonstrated by structural examinations with the help of scanning electron microscopy (SEM), profile recording and microhardness measurements as well as by tribological tests conducted using the pair of “cast iron - chromium” (typical friction pair of the cylinder-piston assembly in the most modern engines).
