The particle size effect in abrasion studied by controlled abrasive surfaces

Wear, 1999
The effect of abrasive particle size on the wear rate is well known. For small particles the wear rate increases with increasing particle size. Above some critical size the wear rate becomes almost independent of further size increases. Several theories have been presented to explain the size effect.

Non-Abrasive Surface Preparation

SSPC 2017 Greencoat, 2017
While traditional cleaning solutions can be time consuming, costly and ineffective, dry ice blast cleaning provides a completely dry solution that cleans faster and more efficiently, while reducing downtime and supporting environmental initiatives. This presentation will discuss the basic concepts of dry ice cleaning.

A comparison of the abrasiveness of six ceramic surfaces and gold

The Journal of Prosthetic Dentistry, 1991
A type III gold alloy and six different ceramic surfaces were secured in an abrasion machine opposing extracted teeth to determine their relative abrasiveness and resistance to wear. The rankings of restorative materials from least abrasive to most abrasive were: gold alloy, polished; cast ceramic, polished; porcelain, polished; cast ceramic, polished ...

Surfaces with Sustainable Superhydrophobicity upon Mechanical Abrasion

ACS Applied Materials & Interfaces, 2016
Surfaces with sustainable superhydrophobicity have drawn much attention in recent years for improved durability in practical applications. In this study, hollow mesoporous silica nanoparticles (HMSNs) were prepared and used as reservoirs to load dodecyltrimethoxysilane (DDTMS).

Evolution of Surface Roughness of Ti Plate in Abrasive and Abrasive-Less Polishing

Advanced Materials Research, 2010
Polishing the titanium plate is commonly necessary step before being used in many fields. Experiments of the titanium plate polished in the condition of including abrasive and existing abrasive are carried out to study the roughness of polished surface in given state.

Effect of surface topography on the dynamics of the abrasive particles during micro-abrasion

Wear, 2015
Abstract During abrasive wear, the wear mechanism has been shown to be associated with the movement of the active particles present at the wear interface: rolling, evidenced by indentations on the worn surface, and sliding, which produces scratching and/or ploughing.

Abrasives selection for surface pretreatment

Transactions of the IMF, 2009
Choosing the correct abrasive for impact treatment processes is a bewildering process. There are three different types of fused alumina, there are glass beads and ceramic beads, steel shot, chilled iron and steel grit, plastic abrasives, vegetable abrasives, silicon carbide – the list is almost endless!

Effect of abrasive size on machined workpiece surface in solid abrasive lapping

SPIE Proceedings, 2000
This paper studies the effect of abrasives size on machined workpiece surface in solid abrasives lapping. From the results it can be seen that the value of roughness of the machined workpiece surface increases as the size of abrasives increases. Its principle is same as ultraprecision grinding and tradition lapping.

Improvement of Local Surface Quality by Using Single Abrasive Abrasion Process

Tribology Letters, 2007
AFM-based wear process actually is single abrasive abrasion process. It is widely employed in the surface micro/nano machining for fabrication of structures at the nanometer scale exhibiting high removing ability of nanometer scale materials. In this study, application of AFM-based single abrasive abrasion process in the local surface quality (surface ...

Characterisation of surface abrasivity and its relation to two-body abrasive wear

Wear, 1997
Abstract In this paper a new method for numerical characterisation of the abrasivity of surfaces and relating this to two-body abrasive wear is described. In a previous work particle angularity was characterised by a newly developed numerical parameter, the quadratic spike parameter (SPQ-particles), which approximates the major protrusions of a ...
