چکیده انگلیسی
To determine the wear resistance of journal bearings (JBâ²s) under lubricated condition, this paper aims to provide an alternative method using an adapted TE-66 micro-scale abrasion tester which was adapted to generate accelerated lubricated wear on actual JBâ²s. Two actual JBâ²s with different coatings were investigated. The load (in the range 1-3Â N) and sliding distance (in the range 39.9-797.7Â m) were varied to see the wear progression. The wear scars were assessed by SEM and optical profilometry, which exhibited the common abrasive and adhesive mechanisms of actual JBâ²s. In the paper, test procedures and wear behaviors were analyzed in detail. Thus, according to the coatings from the JBâ²s characterized, the wear resistances found were: 9.06E+13Â N/m2 for Pb-Cu-Al, 1.02E+15Â N/m2 for Cu-Al, and 1.33E+14Â N/m2 for Sn-Al-Si. Finally, the tester demonstrated good adaptability to reproduce accelerated lubricated wear in JBâ²s.
