Tribological behavior of Cu-MoS2 and Ag-MoS2 nanocomposite lubricant was studied. Cu nanoparticles produced by electrical explosion of copper wires and Ag nanoparticles prepared by electrospark erosion were employed as metal cladding modifiers of MoS2 nanolamellar particles. The tribological tests showed Cu-MoS2 and Ag-MoS2 nanocomposite lubricants changed the friction coefficient of the initia...
In this study, the dynamic range and dispersion stability of a shear-type magnetorheological (MR) grease damper were experimentally investigated as important characteristics affecting performance semi-active vibration suppression. Furthermore, was applied to suppression small single-degree-of-freedom model structure subjected seismic excitation. The test results indicated that it has 157 times,...
In this paper, physicochemical characterization and analysis of total metal concentration of greases and wastewater samples from two wastewater treatment plants in the North of Morocco, Tangier and Tetouan, were carried out. The samples were taken in the winter period of the year 2011-2012. For two case studies of wastewater treatment plants in Tangier and Tetouan (WWTPTG and WWTP-TT), waste so...
