Abstract

The effect of electric potential on the microindentation resistance is investigated experimentally for aluminum and zirconium samples. The effects of the electric potential proper applied to a sample and of the potential arising due to contact potential difference between metals with different electron work functions are compared. A qualitative equivalence of these two types of electrical action is revealed. A possibility of a significant (over 10%) change in the metal microhardness due to the above nentioned actions is established.
