The simulation results show that the main phase transformation of abrasive scratching Gradia is the amorphization of the graphite and diamond components. The nano-diamond particles are generated on the downside amorphous subsurface ( Fig. 5 (f)) and the ahead contacted region between the abrasive and subsurface ( Fig. 5 (e) and (g)).
The microstructure of the heat-treated steel corresponds to a Plasticity Induced Transformation (TRIP) steel with σu = 890 MPa, S = 30%, and hardness of 22 HRC. Both types of steel were subjected to abrasive wear (ASTM G-65) with silica sand particles and loads of 45, 66,5, and 130 N. The TRIP effect (transformation of retained …
The abrasive wear of monocrystalline silicon showed a new 74 phase transformation route, i.e., an initial diamond cubic silicon turned into high density amorphous 75 phase beneath the moving particle and, then transformed into low density metastable amorphous 76 phase in both two-body and three-body abrasion [24,25]. Consequently, phase ...
Abstract: The effect of abrasive shape on the three-body abrasion behaviors of monocrystalline silicon was investigated via molecular dynamics. The axial ratio of abrasive particle varied from 1.00 to
The stochastic nature of material non-homogeneity, machine/ tool vibration, abrasive tool degradation, chip formation and undefined contacts makes it difficult to model the abrasive processes theoretically. ...

In this review, the optimization methods of ceramic corundum abrasive properties are introduced from three aspects: precursor synthesis, particle shaping, and …
abrasive blasting on the transformation of zirconium oxide. The research has shown that this type of surface treatment causes the transformation of the tetragonal phase into a monoclinic one.
In this study, the hardness, fracture toughness, and abrasive wear behavior of three zirconia-toughened MoSi 2 composites and a zirconia-toughened Al 2 O 3 were examined and compared with similar materials containing no zirconia second phases. Each of the composites contained 20 vol.% ZrO 2; however, the polymorph of the added …
The purpose of the research was to investigate the effect of abrasive blasting on the transformation of zirconium oxide. The research has shown that this type of surface treatment causes the transformation of the tetragonal phase into a monoclinic one. The samples were examined using X-ray diffraction (XRD). The study confirmed the assumption.

from the Gemmarum et Lapidum, Anselmi Boetii de Boodt, Prague, 1609. De Boodt tell us that "Through a rope, the wooden wheel moves a tin wheel, on which water mixed with emery powder is sprinkled." (Boodt, 1609, pg. 38) We not only see a continued use of tin but we also get an idea of one of the abrasives they were using to cut and polish colored …
The effect of abrasive shape on the three-body abrasion behaviors of monocrystalline silicon was investigated via molecular dynamics. The axial ratio of abrasive particle varied from 1.00 to 0.40 to mimic abrasive shape. It has been observed that the particle's movement became sliding instead of rolling when the axial ratio was smaller …
A process to generate a reflective surface. Normally, the polish is generated by using a fine-micron or sub-micron abrasive particle in combination with a liquid. Polishing is a "wet" process. Often the polishing process utilizes a pad to contain the abrasive, so polishing may not be a "loose abrasive process.". The pad is softer than ...
