FIELD: aviation.
SUBSTANCE: value of the surface energy is determined taking into account their hardness and electronic work function. To determine the electronic work function on the pre-cleaned from the contamination of controlled parts, the contact potential difference is measured with a device having an amplifier with pre-filtering of the signal, a microprocessor for basic signal processing, control and indication, an information display indicator, and a sensor having an electromechanical oscillatory system in its composition, an electromagnetic oscillator, a buffer signal amplifier, a vibrating measuring electrode made of material with known electron work function, and then surface energy is calculated by a predetermined formula.
EFFECT: providing the possibility of determining the surface energy of metal parts of aeronautical engineering made of multicomponent alloys in the process of their production, operation and repair.
