Description
Summary:An important problem in modern equipment is the friction between metal surfaces in various mechanisms. Friction leads to wear of rubbing parts. To reduce the friction coefficient, it is proposed to treat the surfaces of the rubbing parts with a suspension containing a high percentage (more than 20%) of ultrafine detonation nanodiamond. During such treatment, nanodiamond particles penetrate into the treated substance and create a thin surface layer (up to 1,000 nm, depending on the degree of treatment), leading to a more smooth micro-slip effect, due to which the friction coefficient decreases. The resulting surface layer consists of a metal matrix and diamond nanoparticles embedded in it. The paper shows the results of the surface analysis of a steel part using the optical and X-ray diffraction methods, and provides information about the change in the coefficient of friction of steel parts.
