ALGORYTHM FOR VARIABLE PSEUDOVISCOSITY COEFFICIENTS UNDER AN EXPERIMENTAL BASIS
Constitutive equations between stresses and deformations for oils with pseudo-viscosity properties are usually described by the Rivlin-Ericksen relations. In these relations two pseudo-viscosity coefficients occur. Up to...
ALKYLPOLYGLUCOSIDES, AS SURFACE ACTIVE COMPOUNDS, DECREASING FRICTION COEFFICIENT AND WEAR IN TRIBOSYSTEMS MADE FROM DIFFERENT MATERIALS
As additives improving water lubricity alkyl polyglucosides (APGs) were proposed. Two APGs having alkyl chains of various lengths and various polymerization degree were tested. The tribological tests were performed using...
IRON POROUS SLIDE BEARINGS IMPREGNATED WITH A SELECTED IONIC LIQUID
This article presents some selected results of the research on the slide porous bearings, sintered from the iron powder Höganas NC.100.24, with 2.5% of copper addition by weight, impregnated with selected ionic liquids,...
AN ANALYSIS OF THE INFLUENCE OF JOURNAL’S HELICAL GROOVE ON THE WEAR AND LOAD CAPACITY OF THE SLIDING BEARING
The article presents the results of a sliding bearing with a helical groove on a journal. The studies included wear tests with contaminated lubrication oil and computer simulation of oil flow based on which the load capa...
TRIBOLOGICAL PROPERTIES OF THE AL2O3 LAYER MODIFIED BY TUNGSTEN DISULFIDE IN COOPERATION WITH PEEK/BG MATERIAL
In this article, the authors pay attention to the tribological behaviours of Al2O3 layers modified by tungsten disulfide powder. Oxide layers of Al2O3/WS2 were obtained by using hard anoding treatment in multicomponent e...
