The Kirkendall effect has important practical consequences.
2.
The Kirkendall effect arises when two distinct materials are placed next to each other and diffusion is allowed to take place between them.
3.
The ongoing intermetallic reactions also cause Kirkendall effect, leading to mechanical failure of the joint, similar to the degradation of gold-aluminium bonds known as purple plague.
4.
Small changes in the chemical environment will allow control of reaction and diffusion at room temperatures, permitting manufacture of diverse polymetallic hollow nanoparticles through galvanic replacement and the Kirkendall effect.
5.
Macroscopic evidence for the Kirkendall effect can be gathered by placing inert markers at the initial interface between the two materials, such as molybdenum markers at an interface between copper and brass.
6.
In deriving the first equation, Darken referenced Simgelskas and Kirkendall's experiment which tested the mechanisms and rates of diffusion, and gave rise to the concept now known as the Kirkendall effect.
7.
The coordinate transformation theory reveals that the Kirkendall effect is caused by a shift between the coordinate systems of diffusion equation like the Doppler effect relevant to a wave equation is caused by a shift between the fixed coordinate system and the moving one.
8.
Use of Darken s equation in this form has important implications for determining the flux of vacancies into a material undergoing diffusion bonding, which, due to the Kirkendall effect, could lead to porosity in the material and have an adverse effect on its strength.
9.
The phenomena are so called Kirkendall effect and it was considered that we cannot understand it from the existing theory of binary interdiffusion in those days . As a result, a new concept of intrinsic diffusion was then introduced for understanding the Kirkendall effect in the interdiffusion problems.
