Abstract
The results of the oxidation kinetics of lead babbit B (PbSb15Sn10) with potassium in the temperature range of 373...473 K, the resulting oxidation products of alloys and their microstructures are considered. It is found that the oxidation process in the entire temperature range studied can be described with a high degree of accuracy by a fourth degree polynomial. In experiments, a periodic change in the rate of oxidation with time is noted. The kinetic and energy parameters of the alloy oxidation process is determined. It is established that the addition of potassium increases the oxidizability of the initial alloy B (PbSb15Sn10).
