How to Calculate and Solve for Body Diffusion | Diffusion in Alloying

Last Updated on January 12, 2023

The image above represents body diffusion.

To compute for body diffusion, three essential parameters are needed and these parameters are Concentration at Depth x (Cx), Concentration at the Surface of the Body (Csand Initial Concentration (Co).

The formula for calculating body diffusion:

B.D. = (Cx – Co)/(Cs – Co)


B.D. = Body Diffusion
Cx = Concentration at Depth x
Cs = Concentration at the Surface of the Body
Co = Initial Concentration

Let’s solve an example;
Find the body diffusion when the concentration at depth x is 5, the concentration at the surface of the body is 10 and the initial concentration is 2.

This implies that;

Cx = Concentration at Depth x = 5
Cs = Concentration at the Surface of the Body = 10
Co = Initial Concentration = 2

B.D. = (Cx – Co)/(Cs – Co)
B.D. = (5 – 2)/(10 – 2)
B.D. = (3)/(8)
B.D. = 0.375

Therefore, the body diffusion is 0.375.
