Effect of Chemical Exploitation Preparation on the Tribological Properties of CuSn10 Bronze within the Friction Process

Abstract

The paper presents results of tribological properties of the kinematic pair: X210Cr12 steel / CuSn10 bronze, lubricated within the friction process by engine oil SAE 20W/40, and by the same lubricant modified by chemical exploitation preparation. Research of tribological properties were carried out using the tester T-05 (type tester roll - block). Tests have been carried out in two stages. In the first order - friction force, wear of the kinematic pair and the temperature of the friction area have been determined. The objective of the second phase was to micro roentgen spectral analysis of the surface friction zone. On the basis of these studies, the analysis of the elemental composition of the surface layer in the track wear have been made. The modification purposefulness of lubricant SAE 20W/40 by chemical exploitation preparation has been shown.

A tribological studies of graphite solid lubrication effect on UHMW polyethylene in silicone oil lubricated conditions

“…Using of solid lubricant materials is an effective way to simplify design and prolong service life of the operating systems under harsh conditions [1][2][3]. The fields in which application of solid lubrication is more preferable than oil or grease lubrication are especially aerospace or food industry and also conditions in which mechanical parts works under high temperatures and pressure [4].…”
