| Abstract | In order to clarify the influence of temperature below freezing point on the tribo-oxidation of steel–steel friction pairs, tribological behaviour of certain steel from −55 ◦ Cto20 ◦ C was investigated using a ball-on-disk tribometer in a thermotank which could provide environment with constant temperature and humidity. The counterbody was a ϕ3mm GCr15 steel ball. The normal load was 0.5 ∼ 2.5 N and the sliding velocity was 0.319m/s. Worn surface on the steel, wear scar on the steel ball and wear debris were observed and analysed by SEM and EDS. It was found that the friction coefficient presents a sudden increase when the ambient temperature drop from 20 to −10 ◦ C. This is caused by decrease of relative humidity. The friction coefficientmaintains the same value when the temperature change is between−10 and−55 ◦ C. A drop of temperature from20 to −55 ◦ C aggravated wear of the steel. Analysis on tribochemical reaction process indicates gradually weakened oxidation of wear debris along with a drop of temperature should account for the aggravation of wear. Furthermore, along with the drop in temperature, the worn surface became rougher and more structure fractures were formed on the friction track, which led to more severe abrasive wear of the steel. Drop of temperature increased abrasive wear but decreased adhesive wear. |
