THE INFLUENCE OF WATER ON THE TRIBOLOGICAL PROPERTIES OF SHOE SOLES
Journal Title: Tribologia - Year 2015, Vol 264, Issue 6
Abstract
The methodology and the frictional of results of shoe soles made of natural leather, thermoplastic rubber and synthetics rubber cooperating with the samples made of ceramics and wood were presented. The tests were performed in conditions of technically dry friction and with the presence of water. The analysis of the test results lead to a conclusion, that the most appropriate material for shoe soles is a natural leather because it has the similar coefficient of friction in conditions of technically dry friction and in the presence of water.

THE EFFECT OF FILLER CONCENTRATION IN GREASE ON THE EFFICIENCY OF THE LUBRICATION OF STEEL SLIDING PAIRS WORKING IN MIXED LUBRICATION
The paper presents the results of preliminary studies into the effect of different fillers (Bi2O3, Sb2O3, CuO, ZnO, TiO2) in calcium grease (Machine Grease 2) on the efficiency of the lubrication of steel sliding pairs....
PROPERTIES OF HYPERSONIC SPRAYED NANOSTRUCTURED CARBIDE COATINGS
Nanostructured cermet coating was sprayed from agglomerated nanostructured WC12Co powder feedstock by means of hypersonic spray process (HVOF). Grains of tungsten carbide nanopowder were analysed by a scanning electron m...
THE ANALYZE OF FRICTION CONDITIONS ON A RAKE FACE WHEN FINISH TURNING ON THE BASE OF CHIP THICKNESS CHANGES
In the paper, the results of the analysis of theoretical equations to calculate middle coefficients of friction on a tool rake face during finish cutting are described. Equations viewed were compared with experimental re...
EVALUATION OF THE HOMOGENEITY OF THE WORKING SURFACE OF CAST IRON BRAKE DISCS
This article deals with the one of the most important elements of modern braking systems, which is a brake disc. A brake disc is the one of more stressed parts of the braking system, and its quality and design largely de...
