- Lecture 4: Diffusion: Fick’s second law
• Learn how to deduce the Fick’s second law, and understand the basic meaning, in comparison to the first law • Learn how to apply the second law in several practical cases, including homogenization, interdiffusion in carburization of steel, where diffusion plays dominant role

Time-dependent diffusion in finite bodies can soften be solved using the separation of variables technique, which in cartesian coordinates leads to trigonometric-series solutions
- Fick’s Laws of Diffusion: Formulas, Equations, Examples
Fick’s laws explained with examples: Learn the formulas and equations for Fick’s first second law of diffusion with their derivation application in biology
- Ficks laws of diffusion - Wikipedia
They can be used to solve for the diffusion coefficient, D Fick's first law can be used to derive his second law which in turn is identical to the diffusion equation
- 6. 26: Steady State Diffusion, Diffusion Coefficient, Fick’s Second Law
Therefore, Fick's first law tells us how concentration change flows over the region between two different concentrations Example: If you heat steel in a carbon rich atmosphere, carbon atoms will diffuse into the steel, hardening it

For non-steady state diffusion, we’ll assume that diffusion occurs through a semi-infinite 1-D solid in this class Thus, the solution to Fick’s Second Law is:
- Ficks Second Law - UMD
Fick’s second law gets into more detail, telling us the rate at which concentration is changing at any given point in space This law takes the form of a “partial differential equation”, that is, an equation that allows us to solve for rates involving both time and space
