In this work, the ball-on-flat experiments were performed on stainless steel-420 versus 100cr6 friction pairs under dry, minimum quantity lubrication (MQL) and pool conditions. Then, the wear studies in terms of volume loss, profile...

The Leica DCM3D microscope is applied to collect the profile data of the grinding...

...) . Based on the measured average track widths measured, track depths for the BOD wear tests performed were within the range 8 μ m–30 μ m. However, based on the SEM and OS images recorded, the significant amount of adhesive wearing combined with the deposition of material to the ball surface...

...Luanxia Chen; Zhanqiang Liu; Yukui Cai; Bing Wang The cylinder block/valve plate interface in the axial piston pump has been proven to be easily worn out, which will increase power loss and reduce its efficiency. The valve plate surface is required to be manufactured with low viscous friction...

... that the nanolubricant produced a tribofilm reduced the friction for 40% and wear 90%, while the electrical conductivity remained to be stable during tribotesting. Surface characterization of the tribofilm showed that there was a layered pyrophosphate on the wear track. The in situ impedance study about tribochemical...
