Part 5: Diffusion Flashcards
1
Q
What causes diffusion?
A
Thermal energy and a concentration gradient (atoms move from high to lower concentration)
2
Q
What is the difference between steady-state and non-steady-state diffusion?
A
Steady-state diffusion is independent of time
3
Q
What is interdiffusion?
A
Atoms from one material move into another
4
Q
What is self-diffusion?
A
Atoms moving through in a pure metal
5
Q
What are the 2 atomic mechanisms that create diffusion?
A
Activation energy and number of vancancies
6
Q
What is the driving force of steady state diffusion?
A
Concentration gradient
