Note (General): Among Diamond-Like Carbon (DLC) coatings, hydrogenated amorphous carbon (a-C:H) coatings are of great interest since some of them exhibit friction coefficient in the millirange, so-called 'superlow friction' in vacuum. However, there are still points to be clarified and improved to employ them as solid lubricant for space use. For example, in space environment solid lubricants are required to function at both low and high temperature. In such an extreme environment, it is necessary to know the evolution of the tribological behavior in temperature, leading to their application limit. In this work, pin-on-disk friction tests were conducted at various temperatures under vacuum condition. For all temperatures, superlow friction regime could be reached, as it was observed usually at room temperature. However, an effect of temperature is evidenced on the duration of 'running-in' phase, i.e. the number of cycles required to reach a superlow friction regime. The lower the temperature was, the longer this duration was. Also, the application limit in temperature was found between 200 and 300 C, at which the friction coefficient slowly increases after running-in, to reach values above 0.01.
