Characterisation of surface abrasivity and its relation to two-body abrasive wear
Wear, 1997Abstract 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 ...

Finishing of structured surfaces by abrasive polishing
Precision Engineering, 2006A new polishing process for the finishing of structured optical elements was introduced by the authors. Abrasive polishing using pin type and wheel type polishing tools made of polyamide was applied to improve the surface roughness of structured molds exhibiting fly-cut and precision ground V-grooves.

The Effects of Etching, Micro-abrasion, and Bleaching on Surface Enamel
Journal of Dental Research, 1993Conservative techniques for improving the appearance of discolored teeth have become popular in the past decade. These include: in-office bleaching with 30% hydrogen peroxide, which is applied on etched enamel with a gauze pad and then exposed to a bleaching light; home bleaching with a mild form of peroxide, such as 10% carbamide peroxide, which is ...

A research of the working surfaces of abrasive composites
World Journal of Engineering, 2012In this paper, the method for the calculation of disperse fillers concentration on effective surface composite (active grains) is developed. The method is proven by research of composite materials on PTFE-bond containing diamond powders. The stability of active diamond grains in PTFE is defined by composite material density, uniformity of a powder and ...

Surface microstructure and abrasion resistance of concrete
Cement and Concrete Research, 1987Abstract The influence of several surface finishing techniques on the abrasion resistance of concrete specimens of various mix compositions has been measured by means of a rolling-wheel apparatus. Microstructural features of the cement matrix components of the exposed surfaces have been studied by mercury intrusion porosimetry and microhardness ...

Abrasion resistance of surface layers
1998A number of surface layers obtained by coating and surface treatments i.e. DLC, SiC, SiC+DLC, Al_2O_3, Al_2O_3+Phosphates, CrN, case hardening and boriding were tested both in a "dry sand / rubber wheel" apparatus and in service. The service test was carried out in a vegetable oil factory. The screen bars of an oil extracting press were surface treated
