Evaluation of the real contact area in three-body dry friction by micro-thermal analysis [PDF]
, 2009 Many tribological properties and wear mechanisms occurring on the micro-and nanoscale are strongly controlled by the so-called real contact area (Ar) which is a small fraction of the nominal or apparent contact area (Aa). The determination of Ar is often

Tribo-corrosion of steel in artificial saliva [PDF]
, 2014 Stainless steel is widely used as dental implant. However, there has been little work on the micro-abrasion of such materials in laboratory simulated oral environments, where abrasion, sliding wear can interact simultaneously.

Fretting wear of TiN PVD coating under variable relative humidity conditions – development of a “composite” wear law [PDF]
, 2008 Fretting is defined as a small oscillatory displacement between two contacting bodies. The interface is damaged by debris generation and its ejection from the contact area.

The Running-in of Lubricated Metal-Metal Contacts—A Review on Ultra-Low Wear Systems
Lubricants, 2018 The running-in of lubricated metal–metal contacts leading to ultra-low wear is inseparably connected with the formation of the third body and vice versa. Adequate tribological stressing provides the system with a power density that leads to complex

A Simple Technique to Remove an Incarcerated Ceramic Liner in Revision Hip Arthroplasty
Arthroplasty Today, 2023 Extraction of a well-fixed ceramic liner during revision total hip arthroplasty can be technically challenging, particularly when acetabular fixation screws prevent en bloc removal of the shell and insert without causing collateral damage to the adjacent
