Abstract
The effect of the chemical composition of lubricants containing surfactants on the coefficient of friction, temperature, and linear wear of iron-based powder antifriction alloys is shown. The conducted research has shown that saturation of porous structures made of Fe, Fe + Cu and Fe + 2.5% Cu + 2% Gr with lubricants based on carboxylic acids or other surfactants (surfactants), followed by their application in the area of contact of rubbing elements, significantly improves the tribological characteristics of the studied powder materials. The experiments demonstrated that the use of a mixture of mineral oil I-20A and an alcohol solution of oleic acid as a lubricant lead to a significant reduction in the break-in period of the samples, by approximately 4-6 times. In addition, there is a decrease in the coefficient of friction, which does not exceed 0.01-0.007 in a stable mode, after which the system practically switches to a mode of operation with minimal wear.
Using the electron probing microanalysis, the features of the formation of intermediate structures improving tribological properties of powder materials based on iron-copper-graphite, as well as the influence and composition of lubricants containing surfactants on microstructure of the surface layer of friction pairs were determined.
