چکیده
The tribological behavior of novel 7.5 wt% carbon nanotube-based lubricant greases in PAO (polyalphaolefin) oil with and without 1.0 MoS2, together several other commercial such as calcium, lithium, were studied. test results showed a marked reduction frictional coefficient achieved by the CNTs based grease samples an average benefit around 30% compared to conventional greases. steady state under 1.00 GPa contact pressure mixed lubrication regime fretting best terms friction obtained Steady tests at higher 1.67 proved have lower for containing MoS2; otherwise MoS2 value CoF comparable calcium lithium greases, both boundary regime. protection against wear, considerable decrease (?60%) reference parameter was measured (NLGI 2) comparison worst ?22% grease. data indicated that our nanotube show superior properties will promising applications corresponding industry.

Crack Behavior of the Aluminum Alloy 2024 Under Fretting Conditions
The initial stage of fretting fatigue crack growth is significantly influenced by tangential force induced by fretting action along the contact surface where a mixed-mode crack growth is involved. Fretting crack behavior of aluminum alloy 2024 was studied, taking into account the problem of contact asperities. Finite element was used for the determination of the stress field near the contact su...
