Effect of Abrasive Size on Wear

Modelling Friction and Abrasive Wear of Elastomers

In order to properly model the friction and wear of elastomer materials, it is essential to understand some specific mechanical and tribological features. Mechanical characteristics of elastomer materials are different from those of metals and other relatively hard materials. Elastomers can bear large deformations, the stress-strain curves are non-linear, time and temperature dependent. When th...

Effect of Abrasive Particle Size on Abrasive Wear Resistance in Otomotive Steels

If one of the surfaces which are in touch is rough and hard, it chips the other surface due to relative motion or touching forces. The wear is called two-body abrasive wear. If there are free abrasive particles between the two bodies, the wear is called three-body abrasive wear. The free abrasive particles may be external material dust or the remains of chipping. Usually, the wear starts as a t...

Evaluating abrasive wear of amorphous alloys using nanoscratch technique

The hardness and elastic modulus of several Zr, Pd, Cu, and La-based amorphous alloys were investigated using nanoindentation. Abrasive wear of these alloys was also evaluated and compared using nanoscratch techniques under a ramping load. Damage caused by scratching was examined using SEM. Material pile-up took place in all scratched samples, but to different degrees. The scratched surface was...

Nanoscale Abrasive Wear of CoCrMo in In Situ TEM Sliding

The mechanical behaviour of materials at nanometre dimensions has been a major recent topic of research. In this study, the wear properties of a *60-nm thin foil made of the ductile fcc phase of a CoCrMo alloy were examined using in situ sliding test in a transmission electron microscope by sliding a silicon AFM tip on the fcc matrix under an applied normal load of 416–1,279 nN. The material ne...
