Abstract
The selection of the necessary and sufficient number of Duralumin samples in determining the surface energy of metal aviation components is considered. The surface energy is determined by measuring the contact potential difference, which depends on the electron work function for the samples. The number of samples for measuring the contact potential difference must be no less than five.
