Determining the Electron Work Function of Metallic Aircraft Components from the Contact Potential Difference

A method has been developed for determining the contact potential difference and electron work function of metallic aircraft components, on the basis of a specialized measuring system. Attention is paid to the determination of the surface layer of the aircraft components, the electronic theory of metals, the contact potential difference, and its measurement by means of static and dynamic capacitors. Methods of nondestructive monitoring of metallic aircraft components are developed and assessed.
