Abrasive Wear

Abrasive wear occurs when a hard surface or hard particles pass over a soft surface, causing loss of material [1]. However, the abrasive grooves can be found on the wear tracks of the sliding friction […]

Adhesive Wear

Adhesive wear occurs when two solids are in a sliding contact and the atomic bonding forces occurring between the materials on the interface are stronger than the strength of the surrounding area in either of […]

Superlubricity

Superlubricity is a recently invented term in tribology, which is generally defined as the state, at which the friction coefficient is low. The definition of “low” is not quite clear, but it can be assumed […]
