Effect of airborne-particle abrasion with a novel spherical abrasive on the zirconia surface

The Journal of Prosthetic Dentistry, 2023
A novel zirconia-alumina composite (ZAC) particle has yet to be studied for airborne-particle abrasion in a bonding protocol for the zirconia surface.The purpose of this in vitro study was to evaluate the shear bond force of resin cement to yttria-stabilized tetragonal zirconia polycrystal (Y-TZP) when using spherical ZAC particles to conduct airborne ...

Effects of abrasive types on the surface integrity of abrasive-flow-machined surfaces

Proceedings of the Institution of Mechanical Engineers, Part B: Journal of Engineering Manufacture, 2016
In this article, the effect of abrasive types on the abrasive flow machining process was investigated. Four groups of abrasive media were prepared with different types of abrasives: SiC, AL 2 O 3 , B 4 C and ...

Metallic Abrasives for Surface Preparation

CORROSION 1994, 1994
Abstract Specimens of mild steel plate were cleaned to near-white by air blasting with different types, sizes and hardnesses of steel abrasives. The cleaning rate increased as the abrasive hardness increased, and the adhesion between a zinc coating and the blast-cleaned surface improved.

Measurement of coated abrasive surfaces

Wear, 1976
Abstract The measurement and characterisation of coated abrasive surfaces are reported. Four different techniques were used with the emphasis on simplicity, sensitivity and, most important, repeatability. As a process control technique stylus measurement with simple statistical analysis was found to satisfy most of the necessary requirements for ...

Sharpness of abrasive particles and surfaces

Wear, 2004
Abstract The concept of asperity sharpness has recently been developed into a technique for the description of abrasive particle shape. This paper reveals further discoveries on the nature of particle shape and applies sharpness concepts to nominally planar abrasive surfaces composed of self-arranged particle stacks.

Abrasion and surface structure

Wear, 1969
Abstract The nature of the surface structure of abraded materials is described, mainly as it is shown, very sensitively, by electron diffraction at grazing incidence. The Presence, nature and orientation of abrasive particles embedded in the surface, when bonded abrasives are used, is indicated. Other impurities, e.g.

Loose-Abrasive Grinding of Optical Surfaces

Applied Optics, 1972
The aim of the effort reported in this paper was to identify working parameters responsible for the development of a surface shape during lapping with a loose abrasive. A study of the parameters responsible for radius changes during lapping indicates that the complexity of this process can be significantly reduced if proper working parameters are ...

Designed abrasive diamond surfaces

Wear, 1999
With 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, 1976
The 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.
