Abstract:

The mercury and sodium-potassium usually used in liquid sliding contacts have serious drawbacks. The low-melting alloys with a Ga base are of prospective interest and were found to have considerable advantages with respect to mercury or sodium-potassium contacts. The tested Ga alloy has a wide temperature range of liquid state, a low electric resistance 27 as low as Hg and approx. 34 as low as Na-K. It is stable in air up to 500C and has a low vapor pressure. The friction losses are considerably lower than those in Hg sliding contacts, but 4.5 times higher than in Na-K contacts. The contact potential drop is lower than both in the Hg and Na-K contacts.
