AbstractTribological behaviors of an ultrahigh strength Cu–15Ni–8Sn–0.2Y alloy sliding against TC6 titanium alloy in deionized water and seawater under various normal loads and sliding speeds were evaluated. The friction coefficient and wear rate of the studied alloy in deionized water were higher than those in seawater. Seawater played cooling, lu...

The interaction of two grease-based lubricants with and without metallic solid lubricant particles with three different surfaces was investigated in this study. Two differently prepared manganese phosphate coatings and the uncoated substrate were chosen for comparative investigation. The tribological experiments were performed employing a translato...

This work investigates the effect of amines on the lubricity of castor oil-sulfated sodium salt (CSS) emulsion solution for titanium alloys. It is found that the amines with hydrophilic parts such as diglycolamine, have a negative effect on the lubrication while those with hydrophobic parts such as dicyclohexylamine (DCHA), show a synergistic effec...

Reduced friction with increasing normal load in the adhesive regime is revealed by vdW-corrected DFT calculations of various rigid junction models such as Graphene/Graphene, h-BN/h-BN, and Graphene/h-BN. The origin of the friction–load relationship arises from the decreased sliding potential corrugation with increased normal load in the attractive ...

We study a simple model of a conveyor belt. We calculate the relation between the torque M and the belt–pulley slip s. We present numerical results for the M(s) relation, and for the frictional energy dissipation as a function of the slip, which is important for the rubber wear. The theory includes both the belt compliance and the pulley tread bloc...

AbstractCartilage and hydrogels are composed of an elastic network that retains a large volume of water allowing them to efficiently maintain smooth sliding interfaces while under high compressive loads. For hydrogels to be viable candidates to replace osteoarthritic cartilage, a study of their robust long-term use and surface failure mechanism is ...

Perfluoroalkoxy polymer (PFA)-α-phase alumina (α-Al2O3) composites have dramatically (~ 10,000 ×) improved wear resistance compared to unfilled PFA when tested in air. In this study, unfilled PFA and PFA-α-Al2O3 composites were tested using a linear reciprocating tribometer in dry nitrogen (

Because of the mesh-less nature of the smoothed particle hydrodynamics (SPH) method, it has been widely used to simulate surface erosion by impact(s) of angular particles. However, previous SPH models usually adopted uniform resolution for the whole computing domain, which is not conductive to achieve a balance between computational efficiency and ...

In this work, a series of novel binary-doped ionic liquid lubricating films on alkyl silane N-3-(trimethoxysilyl)propylethylenediamine-modified silicon substrates were fabricated. The micro/nano-tribological properties of the films were analyzed. The results showed that the nano-adhesion reduced 63% compared to the silicon substrate and the nano-fr...
