115. Solving a chemistry problem

In the new army of orcs - the Uruk-hai - Saruman decided to use improved durable swords. His engineers suggested using bulk alloying.
Your task: to evaluate the effectiveness of alloying in terms of corrosion resistance of the new sword. Write down the equations for the oxidation of metals. Calculate the feasibility of alloying metal Me with metal Me* based on the requirements for the alloying element (comparisons of Gibbs energy, valency and size of metal ions, evaluation of film continuity). For calculations, use the standard values ​​\u200b\u200bof pressure, temperature.
To obtain the missing reliable data, use any legal methods.
