A Theoretical Model for Metal Corrosion Degradation

Simulations of time profile of pit radii for various parameters/functions. The range of 𝑀(𝑡)various function: (a) 𝑀(𝑡)∈(0,10⁻²⁵), 𝑘_𝑀𝑁_𝑖𝑚~10^-8, (b) 𝑀(𝑡)∈(0,10⁻²⁴), 𝑘_𝑀𝑁_𝑖𝑚~10^-8, (c) 𝑀(𝑡)∈(0,10⁻²⁵), 𝑘_𝑀𝑁_𝑖𝑚~10^-7, (d) 𝑀(𝑡)∈(0,10⁻²⁵), 𝑘_𝑀𝑁_𝑖𝑚~10^-9. Preposition of view 𝑀(𝑡)>0 because chemical potential of the components present in metal are always more than the chemical potential of any solution the line to near of 𝑀(𝑡)~0 are nonrealistic plots so these dictate us to estimate borders of 𝑀(𝑡) function more carefully.
