Introduction and Application of Rotational Abrasion Device to Determine Concrete Pavement Abrasion

Abrasion susceptibility of highway pavements has a great impact on the skid resistance, and consequently accident rate. A rotational abrasion device is introduced, providing the advantage of field simulation of wheel passage, in comparison with existing standard methods. The device was used to measure abrasion susceptibility of concrete pavements with different textures. The obtained results we...

Corneal abrasion

CLINICAL QUESTION What is the best treatment for traumatic corneal abrasion? RESULTS Eye patching does not reduce pain in patients with corneal abrasions. Topical diclofenac does reduce pain in patients with corneal abrasions IMPLEMENTATION Pitfalls to avoid when treating abrasions: Treatment of small abrasions Treatment of larger abrasions When to refer for specialist treatment.

Investigating the effect of nanocoating on friction loss and abrasion in the piston rings

The piston ring which prepares mechanical sealing of a combustion chamber, should have significant abrasion resistance and less friction loss, using appropriate ring coating. The coating widely used is CrN, because of its good abrasion resistance at room temperature. However, it suffers from some shortcomings, such as high abrasion rate at temperatures above 200°C and lack of self-lubricating p...

Determination of scratching energy index for Cerchar abrasion test

Rock abrasivity is an essential factor for selecting cutting tools, estimating tool wear and life, and ultimately, matching various mechanized excavation systems with a given geologic condition. It also assists engineers to determine economic limits of different cutting tools and machines used in civil and mining projects. The Cerchar abrasion test is a simple and most widely used method for ro...
