Title :
An updated view of the aluminum contact interface
Abstract :
The properties and behavior of aluminum in electrical power connections have been extensively studied for more than 50 years. This work provides an overview of several key aspects of the aluminum contact interface. Examined in the light of experimental and theoretical information available today, some popular concepts of the aluminum contact interface that were developed many years ago are seen to be incorrect. The topics addressed are the wide variability of the oxide film, "self healing", "glowing" connections, and the effect of high current density at the metallic conducting spots within the contact.
