Electron Work Function

The electron work function is the energy required to remove an electron from a metal. It depends on the doping and the material.

Physical-Chemical Mechanism of Action

The electron work function (EA) is the energy required to remove an electron from a metal. It depends on the doping and the material. Doped metals have a different EA, which affects their electrical properties.

Metallurgical Relevance & Risks in Welding

A high electron work function can lead to increased corrosion and poorer resistance properties. With incorrect doping, the material may not weld optimally, leading to cracks or distortion.

Workshop Practice & Instructions

Determine the EA of the material before welding. Use appropriate dopants to optimize the EA. If you have questions about EA, contact the material supplier or a metallurgist.
