Although polymer-based self-lubricating materials have rapidly developed recently, intelligent lubricating with self-adaptable lubrication external conditions changing are highly demanded, especially for harsh conditions. Herein, a shape memory epoxy resin based on the biphenyl units (BPEP) tunable tribological behavior was systematically studied. X-ray diffraction (XRD), field emission scannin...

Surface texturing-plasma nitriding duplex treatment was conducted on AISI 316 stainless steel to improve its tribological performance. Tribological behaviors of ground 316 substrates, plasma-nitrided 316 (PN-316), surface-textured 316 (ST-316), and duplex-treated 316 (DT-316) in air and under grease lubrication were investigated using a pin-on-disc rotary tribometer against counterparts of high...

abstract this work investigated the electrochemical and aqueous tribological behavior of hot pressed 2205 duplex stainless steel (dss). dss sintered composites of different volume percent (% vol) of partially stabilized zirconia (psz) was developed using powder metallurgy (pm) technique. electrochemical behaviour was studied at room temperature, using open circuit potential and potentiodynamic ...

in industrial applications, most materials are exposed to wear and friction because multiple conditions are used. however, the tribological properties of these materials can be improved with different techniques. one such technique that improves the frictional property of a surface is the use of self-lubricating coatings. in this study, multicomponent coatings of nominal composition cu-ni3al-mo...

In this paper, dynamic behavior of nanoparticle motion during nanoprobe-based manipulation is investigated. Pushing, pulling or picking manipulation of the particles results in different behavior of rolling, sliding, sticking, or rotation. For a given point of contact of the nanoprobe tip on the particle, nanoprobe load magnitude and direction and critical frictional forces are obtained in all ...

Friction and wear are major limiting factors for the development and commercial implementation of devices fabricated by surface micromachining techniques. These tribological properties are studied using a polycrystalline silicon nanotractor device, which provides abundant, quantitative information about friction and wear at an actual microelectromechanical system (MEMS) interface. This in situ ...
