Science of the Total Environment, 2022
During service or on discarding in the environment, solar ultraviolet radiation (UVR) and mechanical abrasion (MA) often act on plastic surface in combination, which cause the surface of plastics deterioration and micro- and nano- plastics release. Here,

Superhydrophobic surfaces have promised tremendous applications in living and industrial areas for the past two decades. Real applications, however, meet challenges, with the central concern being the robustness to resist mechanical abrasions and impacts.

Mechanisms of abrasive polishing
Wear, 1970Abstract Direct evidence is obtained, using the scanning electron microscope, that fine abrasive polishing operations can occur by a mechanical mechanism in which very small chips are cut. The difference between polishing and abrasion in this respect is only one of degree. Evidence is presented to show how the abrasive particles are held so that they

Journal of Applied Polymer Science, 1983
AbstractRates of wear have been determined for several elastomer materials, using a razor‐blade abrading apparatus based on one described by Champ, Southern, and Thomas. Measurements have been carried out at different levels of frictional power input, corresponding to different severities of wear, at both ambient temperature and at 100°C, and both in ...

Rheological, mechanical, and abrasion characteristics of polymer-modified cement mortar and concrete
Canadian journal of civil engineering (Print), 2020The settlement of fresh concrete or improper operation during construction usually makes the water to cement (w/c) ratio of the cement mortar on the concrete pavement surface higher than designed, which may influence the abrasion resistance of concrete ...

Mechanical Abrasion and Intercrown Spacing
American Midland Naturalist, 1984The crowns of neighboring trees of similar height do not interdigitate but rather are generally separated by spaces called "crown shyness" gaps. In a black mangrove (Avicennia germinans) forest in Costa Rica, the width of crown shyness gaps was positively correlated with the distance pairs of trees or branches adjacent to the gap swayed in the wind (n =

It is important to understand the fragmentation processes and mechanisms of plastic litter to predict microplastic production in the marine environment. In this study, accelerated weathering experiments were performed in the laboratory, with ultraviolet (

On the mechanism of wet abrasive erosion
Tribology International, 1985Abstract A method of testing wet abrasive erosion is presented, together with its mechanism. Many factors have been investigated, including abrasive particle size, velocity and test duration, etc. It is suggested that wet abrasive erosion may be divided into two sub-groups — high stress wet abrasive erosion and low stress wet abrasive erosion.

Pattern abrasion mechanism of rubber
Wear, 1992Abstract To investigate the mechanisms of the pattern abrasion of rubber, the wear processes of an isoprene rubber were examined. After repeated rubbing, small ridges initially appeared on the surface of the rubber. They increased in size as the cracks lengthened at the lower front of the ridges. Propagating crack marks, i.e.
