SEM and XRD results show that the composite that is hot rolled after vacuum forming, has relatively high density and can avoid being oxidized effectively.

The Al, Pb, Cu, Cd, Fe, Sn etc trace element in the electrolytic zinc were accurately and quickly measured by using ICP-AES method.

Aiming at the technology demand of advanced copper interconnection, the effect of pulse current density on cu layer properties such as resistance, crystal size and surface roughness were investigated.
