Abstract: The morphology and collection rate of Cu-30wt%Ag alloy nano particle prepared by induction plasma system with different power were studied. The results indicate that with the power of plasma increasing from 30 KW to 45 KW and then to 60 KW, the average size of Cu-30wt%Ag nano particle of 89 nm, 72 nm and 50 nm is obtained respectively, and the collection rate improves from 47.5% to 50.1% and 55.2%. Meanwhile, the plasma power has an obvious effect on the specific area of nano particle.

Abstract: Mechanical properties of Al-Mg porous materials which were made by self melting reactions at low temperatures are investigated in this work. The results showed that the yield strength of Al-20%Mg was up to 240 MPa, and this is the compressive characteristics of brittle porous materials. The excellent of mechanical properties of Al-Mg porous material was analyzed and the reason was ascribed to the homogenous distributed pore with cell wall strengthening.

Abstract: The Cu-30wt%Ag alloy nanopowders are prepared by induction plasma technology, and the nanopowder is successfully coated by terpineol (C10H18O). The morphology, phase composition and oxidation resistance of nanopowders are characterized by scanning electron microscopy (SEM), X-ray diffraction and thermogravimetric (TG) analysis. When the suitable processing parameters of induction plasma are chosen, the spherical morphology and average diameter about 89 nm of Cu-30wt%Ag nanopowders are obtained. Meanwhile, the Cu-Ag alloy nanopowders which are coated by terpineol are free from oxidation when temperature is below 280°C.
