Abrasive Wheel Wear Test of Anodized Coatings on Aluminum Alloys.

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...

Effect of WC Concentration on Abrasive Wear Properties of the Thermally Sprayed WC -Ni Coatings

In this work the effects of WC concentration on abrasive wear behavior by thermally sprayed WC coating was evaluated using three body abrasive wear tester. A different combination of WC and NI coatings were deposited on steel substrates by flame spraying using powder with different WC concentrations (0 %, 12.5 %, 25 %, and 50 %). Flame torch was used for heating and coating of process. Microstr...

Effect of Abrasive Size on Wear

Characterization of the Micro-Abrasive Wear in Coatings of TaC-HfC/Au for Biomedical Implants

The object of this work was the deposition of a Ta-Hf-C thin film with a gold interlayer on stainless steel, via the physical vapor deposition (PVD) technique, in order to evaluate the properties of different systems subjected to micro-abrasive wear phenomena generated by alumina particles in Ringer's solution. The surface characterization was performed using a scanning electron microscope (SEM...

Abrasive wear response of nanocrystalline Ni–W alloys across the Hall–Petchbreakdown

The abrasive wear of nanocrystalline Ni–W alloys with grain sizes of 5–105 nm has been studied using Taber abrasion testing. The wear resistance of the finest grain size specimen is found to be higher than would be predicted based on hardness alone. This deviation from Archard scaling is traced to mechanically-driven structural evolution, consisting of grain growth and grain boundary relaxation...
