Abstract

The article presents the results of thermogravimetric studies on the influence of alloying additions of manganese on the oxidation kinetics of zinc-aluminium alloys Zn5Al and Zn22Al. The values of the true oxidation rate of the zinc- aluminium alloys Zn5Al and Zn22Al, alloyed with manganese, calculated from the kinetic curves, are given as a function of temperature and the composition of the studied alloys. It is observed that small additions of manganese (0.01–0.05 wt.%) significantly reduce the true oxidation rate of the zinc-aluminium alloys Zn5Al and Zn22Al, while simultaneously increasing the apparent activation energy of this process. Larger additions of manganese (0.1 and 0.5 wt.%) also reduce the oxidability of the base alloy
