Improving wear resistance and reducing the coefficient of friction cylinder liner are critical to improving service life energy savings internal combustion engines. In this paper, effect characteristics cementite precipitation on tribological performance was studied using a medium carbon steel (AISI 1045 steel), which can be used make liners. Three kinds microstructures with different were obta...

The study was conducted to use fish scales powder as animal biomass prepare epoxy composites. Fish is beneficial in reducing environmental pollutants. added the matrix for improving interfacial bonding between and matrix. However, a direct method used composites, samples were cut according ASTM standards mechanical tribological tests. Interfacial interaction investigated by FTIR SEM. It found t...

Micro-hot-embossing is an emerging technology with great potential to form microand nano-scale patterns into polymers with high throughput and low cost. Despite its rapid progress, there are still challenges when this technology is employed, as demolding stress is usually very high due to large friction and adhesive forces induced during the process. Surface forces are dominating parameters in ...

We have performed a quartz crystal microbalance (QCM) study of the uptake and nanotribology of organophosphate (tricresylphosphate (TCP) and t-butyl phenyl phosphate (TBPP)) layers adsorbed from the vapor phase onto amorphous and polycrystalline silicon and octadecyltrichlorosilane (OTS) treated silicon substrates. The materials were selected for their relevance to MEMS applications. About 3–5 ...

The reliability and durability of an ultrasonic motor is usually determined by wear at the contact interface between a drive and a driven element, due to its driving mechanism. Wear control is therefore essential as the key design input to achieve ultimate performance of the ultrasonic motor. In this paper, a high precision and small precise positioning linear stage with an ultrasonic motor as ...
