“…By small additions of Ca, Be, Ce, etc., the oxidation resistance of magnesium alloys has been improved [13][14][15][16], which can be ascribed to the formation of the dense film during oxidation process. Our recent studies also found, that the oxidation resistance of magnesium alloys could be increased by implanting rare earth elements such as Y, Ce [17,18]. Up to now, however, the oxidation mechanism of magnesium alloys is relatively complex and some physical phenomena are still not very clear [19].…”

“…However, gradually, MgO should prevail in the scale in the result of a greater diffusion of Mg 2+ ions than that of Y 3+ ions. Diffusion coefficient of Mg 2+ ions in the MgO lattice amounts to DMg = 110 -6 exp (-150 000/RT) [12], while that of Y 3+ in Y2O3 -DY = 110 -9 exp(-300 000/RT), m 2 •s -1 [13].…”

In spite of the fact that in most applications, magnesium alloys are intended for operation in environments with room temperature, these alloys are subject to elevated temperature and oxidizing atmosphere in various stages of preparation (casting, welding, thermal treatment). At present, the studies focus on development of alloys with magnesium matrix, intended for plastic forming. The paper presents results of studies on oxidation rate of WE43 and ZRE1 magnesium foundry alloys in dry and humidified atmosphere of N2+1%O2. Measurements of the oxidation rate were carried out using a Setaram thermobalance in the temperature range of 350-480°C. Corrosion products were analyzed by SEM-SEI, BSE and EDS. It was found that the oxide layer on the WE43 alloy has a very good resistance to oxidation. The high protective properties of the layer should be attributed to the presence of yttrium in this alloy. On the other hand, a porous, two-layer scale with a low adhesion to the substrate forms on the ZRE1 alloy. The increase in the sample mass in dry gas is lower than that in humidified gas.
