Scanning Electron Microscope (SEM) and Energy Dispersive X-Ray Spectroscopy (EDS) results indicated that adhesive wear occurred during sliding. Adhered particles led to two body abrasive wear and when the adhered...

... importance in numerous fields like aerospace, automotive, and precision industries. Generally, the wear of forming tools can be summarized into three basic stages. First, the initial abrasive wear (phase one) facilitates the progress of the adhesive wear (phase two). Then the tools were ultimately destroyed...

With a decrease in MFI, i.e., with an increase in viscosity of polymer, the adhesive component of friction increases with increasing viscosity while the abrasive wear decreases. At high loads, the plastic displacement increases with an increase...

... to adhesive. At 25 mm/s sliding speed, the a-C:H:SiO x coating delaminates in the wear scar area (Fig. 9( a ) ), and numerous microscopic laminations are observed on the coating surface tested at 75 mm/s sliding speed (Fig. 9( e ) ). We suppose that at this speed, the dominant wear mechanisms become equal...
