Using atomic force microcopy, mechanochemical removal behaviors of GaAs surface slid by Al2O3, SiO2, and CeO2 micro-spherical tips were investigated in ambient environment. High-resolution transmission electron microscope characterization demonstrates that defect-free material was achieved on under the contact pressures much below yield limit plastic deformation, which can be ascribed to water-...
Soil surface rock fragment is considered as an important factor on runoff and soil erosion. However, few studies have been focused on quantitative evaluation of the effect of soil surface rock fragments on runoff components as an integral part of soil erosion process especially in natural conditions. The present study has been conducted to evaluate the effect of soil surface rock fragments ...
In magnetic abrasive finishing (MAF), abrasive grains as a tool move on surface and can remove chip from surface of work piece. In this study AL 6061 tube was considered as the work piece and the effect of finishing parameters such as gap distance between tube and poles, rotational speed of tube, abrasive ration and finishing time on surface roughness was investigated. The mixture of ferromagne...
