The NOMC-Fe composite possessed superior adsorption capacity of Cu(2+) ions and was magnetically separable from solution under an external magnetic field and thus displayed a superior reusability in the recycling test. N-doped ordered mesoporous carbon materials (NOMC) with 2D hexagonal symmetry structure were synthesized via a facile solid …
By using three dimensions finite element method, the temperature distribution has been simulated in grinding of titanium alloy with SiC wheel. The effects of wheel speed, workpiece speed and tangential grinding force on the grinding temperature field were investigated. The results show that the grinding temperature decreases with the increasing of the workpiece speed, and …
Fine grinding produces a surface with little deformation that can easily be removed during polishing. Because of the drawbacks with grinding papers, alternative fine grinding composite surfaces are available, in order to improve and facilitate fine grinding, A high material removal rate is obtained by using grain sizes of 15, 9.0 and 6.0 µm.
