The article presents the results of studying the thermodynamic functions of silumin grade AK12M2. The temperature and cooling time dependences obtained during the experiment are described by the equations that are necessary for calculating the cooling rate of alloys. It is shown that as enthalpy increases, enthalpy, entropy, specific heat and heat transfer coefficient of alloy AK12M2 increase, and Gibbs energy decreases

The results of the study on the effect of antimony alloy anodic behavior AK12M2 alloy, in a neutral environment (at different concentrations - 0.03; 0.3 and 3.0% NaCl). It should be noted that in all cases, the corrosion potential of samples immersin into a solution after some time shifts in the positive direction and then stabilized. In this case, if the stabilization in undoped alloy corrosion potential is observed within 50 minutes, then in doped alloys it occurs twice as fast, within 25-30 minutes, indicating a relatively higher influence of antimony passivation additives.
