THE INFLUENCE OF THE TYPE OF GREASE ON THE SYNERGY OF ITS COMPOSITION WITH PTFE POWDER AND COPPER POWDER

Journal Title: Tribologia - Year 2016, Vol 265, Issue 1

Abstract

Studies of the influence of the type of grease on the synergistic effect of its compositions with PTFE powder and of copper during the lubrication of steel sliding pairs working in mixed friction area of were presented. Two greases, car grease 1S with a lithium thickener and grease STP with calcium thickener, were adopted for analysis. As fillers in the two lubricants, powders of two solid lubricants were PTFE and copper were used. Three lubricating compositions were tested for each of the adopted greases. Two compositions contained one filler of 5% by weight, and the third composition contained the two fillers in the same proportion (5% each). The lubricating properties of the adopted compositions were evaluated based on an experiment conducted with the use of a four–ball extreme pressure tester according to the standard PN-76/ C04147. The effectiveness of the analysed lubricants was evaluated according to four criterion values (wear of the balls d, fusion point Fz, limit wear load Goz, and wear index Ih). The results were statistically handled at the confidence level of 95% using Student’s t-test. The developed test results are shown graphically. Appropriate conclusions were drawn.<br/><br/>
