Antifriction Properties

The most important features of the self-lubricating bearings are the antifriction properties such as friction coefficient and wear resistence and some mechanical properties such as hardness, tensile strength and radial crushing strength. In order to improve these properties new antifriction materials based on iron-copper powders with several additional components (tin, lead and molybdenum disulphide) have been developed by PM techniques. To find the optimal relationship between chemical compositions, antifriction and mechanical properties, in this paper a mathematical model of the sintering process is developed, which highlighted the accordance of the model with data by regression analysis. For the statistical processing of the experimental data the VH5 hardness values of the studied materials were considered. The development of mathematical model includes the enunciation of the model, the establishment of the performance function (optimization) and the establishment of the model equations and verifying. The accordance of the model with experimental data has been highlighted by regression analysis

Antifriction Properties

The formation of boundary lubricating films on the surface of steel during friction in the presence of substances forming complex compounds with iron — dipyridyl, o-phenanthroline, 8-hydroxyquinoline, and ethylenediaminetetraacetic acid, is considered. Boundary layers formed in the presence of complexones increase the antifriction properties of the lubricant at low loads. It has been established that surface films are formed predominantly from base oil molecules.
