Analysis of Abrasion Depth and Rates in Concrete

open access: yesModern Applied Science, 2021
Abrasion is a major problem in hydraulic structures as they are continuously exposed to various types of water. Henceforth, these structures are susceptible to damage and require heavy maintenance. There is a significant demand in finding new techniques for improving the resistance towards the erosion of the concrete used in the construction of ...

Bio-tribocorrosion mechanisms in orthopaedic devices : mapping the micro-abrasion-corrosion behaviour of a simulated CoCrMo hip replacement in calf serum solution [PDF]

open access: yes, 2014
Load bearing implant prostheses such as orthopaedic hip and knee implants may be considered as tribocorrosion systems since the wear processes are a result of combined mechanical and chemical mechanisms.

The effect of pleural abrasion on the treatment of primary spontaneous pneumothorax: a systematic review of randomized controlled trials.

open access: yesPLoS ONE, 2015
BackgroundPleural abrasion has been widely used to control the recurrence of primary spontaneous pneumothorax (PSP). However, controversy still exists regarding the advantages and disadvantages of pleural abrasion compared with other interventions in ...

Experimental Investigation on Hydroabrasive Erosion of Steel Fiber UHPC and Rubber UHPC

open access: yesAdvances in Materials Science and Engineering, 2020
Steel fiber ultrahigh performance concrete (UHPC) and rubber ultrahigh performance concrete (UHPC) adopt the methods of “rigidity overcomes rigidity” and “softness overcomes rigidity,” respectively, to resist the abrasion and cavitation erosion caused by

The effects of chemical treatments on the abrasion resistance of wool fabrics [PDF]

open access: yes, 1981
The low abrasion resistance of wool fabrics compared with many man-made fibre fabrics is known to be a frequent cause of consumer dissatisfaction particularly in pure wool suiting fabrics. Accordingly this project was undertaken to attempt to improve the

Some thoughts on neural network modelling of micro-abrasion-corrosion processes [PDF]

open access: yes, 2008
There is increasing interest in the interactions of microabrasion, involving small particles of less than 10 μm in size, with corrosion. This is because such interactions occur in many environments ranging from the offshore to health care sectors.

Tire Wear, Tread Depth Reduction, and Service Life

open access: yesVehicles
Tires are important for the transmission of forces, good traction of the vehicle, and safety of the passengers. Tires also influence vehicle fuel consumption and cause tire and road wear pollution to the environment in the form of microplastics.

Study on abnormal abrasion of metro pantograph

open access: yes机车电传动, 2023
Pantograph-catenary system is the central system for the power supply of urban rail transit trains. Higher train speed and complex train operating environment can generate severe vibrations on the pantograph-catenary system, resulting in high-frequency ...

Micro-abrasion–corrosion of a Co–Cr/UHMWPE couple in Ringer's solution : an approach to construction of mechanism and synergism maps for application to bio-implants [PDF]

open access: yes, 2010
In studies of tribo-corrosion, the degradation of bio-materials has become of increasing research interest in recent years. This is because, in many cases, the interactions of the tribological and corrosion component in biological environments are not ...

Tyre Wear under Urban, Rural, and Motorway Driving Conditions at Two Locations in Spain and China

open access: yesLubricants
The recently introduced Euro 7 emissions standard regulation foresees the addition of abrasion limits for tyres sold in the European Union. The measurement procedures for tyre abrasion are described in the newly introduced Annex 10 of the United Nations (
