Oxidation behavior and mechanism of Ag-9.8Sn-1.3Bi-0.4Cu alloy powders in different oxidant
Source abstract
Abstract
The oxidation behavior of Ag-9.8Sn-1.3Bi-0.4Cu alloy powders is investigated used by XRD, SEM, EPMA and TEM. The results show that the oxidation behavior in air and air+Ag 2 O is different for Ag-9.8Sn-1.3Bi-0.4Cu microparticles, but that is similar for Ag-9.8Sn-1.3Bi-0.4Cu nanoparticles. The size of oxides formed in air is larger than that in air+Ag 2O and the size of CuO is larger than that of SnO 2 and Bi 2Sn 2O 7. The oxides mainly distribute on powder surface in air oxidation, while those mainly distribute on grain boundaries in air+Ag 2O oxidation. The nucleation priority order of oxides is SnO 2 >Bi 2O 3 >Bi 2Sn 2O 7 >CuO during oxidation both in air and air+Ag 2O.
