Abstract Three mol% yttria-stabilized tetragonal zirconia polycrystals (3Y-TZP) with 0.5 wt% of magnesium oxide (MgO) and 6 wt% of molybdenum (Mo) were prepared by the pressureless sintering process, and the friction and wear behavior of the ceramic composite were studied against the alumina disc. Tribological tests were carried out both at room temperature as well as at an elevated temperature (500 °C). The result revealed that a substantial reduction of ∼50% in the friction coefficient and ∼31% reduction in the wear rate were achieved while 6 wt% Mo was added into the 3Y-TZP matrix operational at 500 °C. No significant tribological influence was observed with the addition of Mo at the normal operating temperature. The minimum coefficient of friction and low specific wear rate were achieved because of the formation of MoO3 in between the mating surfaces at elevated temperature. The worn surfaces were characterized by means of field emission scanning electron microscopy (FESEM). The formation of MoO3 phases was identified by wear debris analysis which was performed with the help of X-ray photoelectron spectroscopy (XPS).

Aisi H13

In this study, AISI H13 steel was plasma nitrided in two different atmospheres, containing 25%N2-75%H2 and 4%N2-96%H2 at a constant temperature of 530oC and 6h-holding time. Dry wear behavior of nitrided samples was determined with pin-on-disc method at 25oC and 500oC, under 10N and 30N loads. The results indicated that the nitrided steels, which had a thin multiple phases white layer (produced at 4%N2-96%H2 atmosphere), didn’t have any wear resistance in ambient and elevated temperatures. However, the nitrided steels, having thick single phase white layer (produced at 25%N2-75%H2 atmosphere), showed better wear resistance in ambient temperature than in elevated temperature.
