Effects of Co3O4 Addition on Friction and Dry Sliding Wear Characteristics of 8 mol% Yttria-Stabilized Cubic Zirconia

Wear assessment of Cr2O3‐/TiAlN‐coated DAC‐10 tool steel against steel and Al2O3 counterbodies

“…As the sliding continues, the CoF tends to decrease due to the deformation or breakage of peaks pertaining to the rougher surface. However, as the process progresses, an increase in CoF was observed, reaching its maximum value and similar phenomenon was observed with Al 2 O 3 counterbody in a study by Aktas et al 49 . It is interesting to note that higher fluctuation in the CoF was observed with the Al 2 O 3 counterbody attributed to its higher hardness.…”

It has been reported that sliding of two harder surfaces experiences higher CoF, 50 because frictional force depends upon the load and the contact area between sliding pair and deformation of material at the contact zone.…”
