The nanostructured AgSnO2 coating applicable to electrical contact material was prepared in the present study. Ag powders were mixed with 12 wt.% of SnO2 nanopowders by means of high-energy ball milling, and then were sprayed on a pure copper substrate by supersonic plasma spraying. The phase composition and microstructure of the coating were characterized and the microhardness, bonding strength and...
SiC-nanoparticle-mixed Sn58Bi solders were successfully produced by electroplating and the mechanical and microstructural properties of Sn58Bi+SiC solders were observed and analyzed in this study. Dispersed SiC nanoparticles by ultrasonic horn were added into Sn-Bi plating solution. With the SiC added Sn-Bi plating solution, solder bumps were electroplated. After electroplating, the solder bump specimens...
In this study, Sn-0.7Cu solder alloy was reinforced with Al2O3 (50 nm) and ZrO2 (45 nm) nano particulates to form Sn-0.7Cu/Al2O3 and Sn-0.7Cu/ZrO2 composites. The volume percentge of the Al2O3 and ZrO2 nanoparticulate reinforcement was kept at 1.5%. The composites were synthesized using powder metallurgy technique assisted with microwave sintering and incorporating hot extrusion as secondary processing...
It has been widely anticipated that the combination of recent advances in nanocomposites technology with traditional and novel resin systems may create materials with enhanced electrical, thermal and mechanical properties. It has been recognised that charge dynamics under an electric field play an important role in determining the electrical performance of a material. In this research, the pulsed...
In this paper, we explore the thermodynamic and dynamic properties of polymer nanocomposites using stochastic molecular dynamics simulation in the canonical ensemble. One of the major parameters that determines the properties of nanocomposites is the filler-monomer interfacial interaction strengths. By varying the interaction strengths as well as temperature of the system we could capture the dynamical...
In this paper, we have investigated the influence of different types and contents nanoparticles on the mechanical properties, structure and dispersion morphology of the LLDPE/inorganic nanocomposites. The results indicate that two-step method has not only good compatibility between two phases but also mechanical properties and processing flowability.
