In tribological applications, such as sliding bearing, polymers tends to wear more quickly than indicated in laboratory wear tests. The reason for this discrepancy has been attributed to the effect of loading conditions. In the current study, the influence of loading mode on the wear characteristics of polyamide (PA66) against steel counterpart was investigated in dry and wet sliding conditions. The polymer was tested under different static and cyclic loading conditions in order to provide a comprehensive understanding of its wear behavior. All tests were performed using reciprocating pin-on-plate tribometer which was constructed to perform wear tests under constant and cyclic loads at constant sliding speed. There was consistent evidence of the effect of loading mode on the wear behavior. At cyclic load, the polymer shows significant increase in wear rates than those found under constant load. Furthermore, under wet sliding, the polymer showed generally higher wear rates compared to dry tests.

“…They declared that under certain boundary parameters at transfer film forms and significantly improvement wear performance. Yu et al [21] studied the friction and wear behaviors of polyamide 66 (PA 66) and rubber-filled PA 66 (PA 66/SEBS-g-MA) composites on a block-on-wheel model friction and wear tester under dry sliding and water lubricating conditions. The friction coefficients of PA 66 and PA 66/SEBS-g-MA composites under water lubricating condition were lower than those under dry sliding condition, but the wear mass losses were higher than those under dry sliding condition.…”

In this study, the tribological performance of originally 40 wt.% fiber glass reinforced polyphenylene sulfide (PPS-G), polyamide 46 (PA46) and their blends were studied at dry sliding conditions. The materials were mixed and extruded on the twin screw extruder. The blends were dried and tribological test specimens were manufactured by using the injection machine. Wear tests were performed with the configuration of a polymer pin on a rotating X40CrMoV5-1 steel disc. Test conditions were atmospheric conditions having 60, 90, 120 N loads and 0.5, 1.0, 1.5 m/s sliding speeds. The obtained results proved that the coefficient of friction for PPS-G, PA46 and their blends is decrease while the applied load and sliding speed values are increase. On the other hand, the specific wear rate is in increase while the applied load and sliding speed values are in increase.

“…However, PA66 shows low notched impact strength and to improve its properties against stress concentration, impact modification of PA66 with polyolefin rubbers/elastomers is well known [4]. Recently, polyolefin elastomers have been introduced as a soft material that can be used as an efficient impact modifier [5][6][7]. The α-olefin-copolymer is a copolymer of ethylene and another α-olefin such as butane or octane and is produced using metallocene catalysts with narrow molecular weight distribution.…”
