Friction and wear characteristics of WC-Co cemented carbides in dry reciprocating sliding contact
TL;DR: In this article, the influence of test parameters such as normal contact force, oscillating velocity and sliding distance on the tribological characteristics of WC-Co cemented carbides with Co concentrations ranging from 6 up to 12% and WC grain sizes in the sub-micrometer scale have been examined in reciprocating sliding wear experiments using a high-frequency TE77 pin-on-plate system.

Wear Behavior of Aluminium Metal Matrix Composite Prepared from Industrial Waste.
TL;DR: Dry sliding wear test was carried out using pin-on-disc apparatus on the prepared composites and the results reveal that increasing the reinforcement content from 10 wt% to 20’wt% increases the resistance to wear rate.

Contact and Rubbing of Flat Surfaces
TL;DR: In this article, the authors compared the deduced dependence of the experimental observables on the load with the experimental evidence and concluded that the most realistic model is one in which increasing the load increases both the number and size of the contact areas.

Sliding wear of conventional and nanostructured cemented carbides
K. Jia,Traugott E. Fischer +1 more
TL;DR: In this paper, a series of unlubricated sliding wear tests in air with pins of cemented carbide composites sliding against silicon nitride disks was performed, and the wear rate was proportional to the hardness with a wear coefficient k = 6.9 × 10 −6 for all materials.

Submicron and ultrafine grained hardmetals for microdrills and metal cutting inserts
TL;DR: In this paper, a new generation of microdrills based on optimized processing and properties such as hardness, hot hardness, toughness, strength and wear resistance was presented and the failure probability of the microdrill could be considerably reduced and the number of drilling strokes was nearly doubled.
