Designed abrasive diamond surfaces
Wear, 1999With the aim to explore their abrasive and grinding properties, flat diamond surfaces with protruding pyramidal abrasive tips have been designed and manufactured. The manufacturing process is a replica technique based on hot filament chemical vapour deposition of diamond onto a silicon wafer, in which the shape, size and packing pattern of the pyramids

Abrasive Surface Deformation of Sapphire
Journal of the American Ceramic Society, 1976The depth of slip and the size of deformation twins introduced into sapphire by abrasive grinding depend on surface orientation. Enhanced depths of slip minimize surface chipping and striations, and grinding can result in basal slip depths of 30 μm and twins 75 μm in size.

The particle size effect in abrasion studied by controlled abrasive surfaces
Wear, 1999The 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.

Abrasives selection for surface pretreatment
Transactions of the IMF, 2009Choosing 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!

Surfaces with Sustainable Superhydrophobicity upon Mechanical Abrasion
ACS Applied Materials & Interfaces, 2016Surfaces 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).

Non-Abrasive Surface Preparation
SSPC 2017 Greencoat, 2017While 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, 1991A 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 ...

Effect of surface topography on the dynamics of the abrasive particles during micro-abrasion
Wear, 2015Abstract 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.

Effect of abrasive size on machined workpiece surface in solid abrasive lapping
SPIE Proceedings, 2000This 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, 2007AFM-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 ...
