Experimental data of friction behavior of IG-110 nuclear graphite during continuous heating under helium atmosphere

Friction and wear tests were conducted using an SRV-5 friction and wear testing system under loads of 87 N and 174 N, corresponding to nominal contact stresses of 1 MPa and 2 MPa, respectively. The tests were continuously heated from room temperature to 900 °C, with temperature stages at room temperature, 100–900 °C, and a holding time of 10 min at each stage.

Friction coefficient, temperature, load, and reciprocating stroke were continuously recorded. The friction coefficient data were processed using the final 60 s of each temperature stage to calculate the mean and standard deviation.​The dataset also contains SEM and TEM characterization images of the worn surfaces. TEM specimens were prepared using focused ion beam (FIB) technology.
