Opis: 330a The aim of this work was to analyse the mechanisms of hindered internal passivation of silver based alloys which was obtained by the modification of basic chemical composition. A generalisation of the phenomenon, experimental verification and the estimated range of micro-element concentration is also introduced. The ability for inoculation of a particular alloy is determined by the differences between the formation energies of oxides, as well as their crystallographic similarity. Therefore, for the investigated Ag-Zn alloys, Mg was selected as the micro-alloying element. The influence of 0.001 up to 0.5 mass % of Mg added to the selected alloys was analysed. By changing the chemical composition,internal passivation was hindered, internal oxidation rate was increased, and considerably greater (redoubled) depths of internal oxidation were achieved.
