For indentors (steel G13L) lowering the temperature has no effect on wear in air or in vacuum.
For rings (steel 40Kh) Iowering the temperature does not affect the wear in air; lowering the temperature in vacuum sharply increases the wear.
The friction coefficient increases with decreasing temperature in vacuum; in air it is smaller than in vacuum and is independent of the temperature.
The friction surface is deformed more in vacuum than in air.
