Abstract

Earlier it was shown that some liquid metals may facilitate the cutting of hard materials, being strongly surface-active media with respect to these solids (decreasing their surface energy), e.g., Zn for steels, Cd for titanium alloys, etc. Recently, a similar physico-chemical principle has been proposed and realized in the course of active metals (Zn, Cd) depositing on the surface of a treated sample (ground tempered steel, 50 HRC) by means of reduction of their cations on a sample used as a cathode in a corresponding electrochemical cell, at room temperature, with a very small amount of active substance, and at very low current densities (∼50 mA/cm2); under such conditions, grinding is 1.5–2 times more effective than in the same aqueous solutions without current.
