Different aspects of the role of wear debris in fretting wear

Wear, 2002
Two different aspects of the role of oxide wear debris in fretting wear are studied by allowing them to escape from the interface during sliding. This is accomplished by laser surface texturing that forms regular micro-pores topography on the friction surfaces which enables this escape.

Genesis and role of wear debris in sliding wear of ceramics

Wear, 2000
Abstract We survey the formation, appearance and properties of wear debris in ceramics and their influence on the wear of these materials. These differ from those of metals, in accord with the different mechanical and chemical properties of ceramics.

Ultramicrotomy on fretting wear debris

Microscopy Research and Technique, 1998
A TEM-sample preparation method for small amounts of fretting wear debris is presented. After embedding in a resin, the debris are ultramicrotomed to ultra-thin sections. In this way, valuable observation of nanocrystalline fretting wear debris originating from TiN-coatings could be rapidly obtained.

Wear Debris

Clinical Orthopaedics and Related Research, 1994
There is a growing concern that osteolytic lesions, often adjacent to otherwise stable implants, are a recent phenomenon caused by some recent change in polyethylene, metal, or other aspect of the total hip construction. This study investigates the possibility that bearings and modular connections used in modern hip replacements are an unappreciated ...

Wear Debris in Total Joint Replacements

Journal of the American Academy of Orthopaedic Surgeons, 1994
In vivo degradation of prosthetic implant materials is increasingly recognized as a major factor limiting the durability of total joint arthroplasty. In vivo degradation occurs primarily by means of wear processes that can generate large quantities of particulate debris. This debris can stimulate an adverse local host response leading to periprosthetic

The production and biology of polyethylene wear debris

Archives of Orthopaedic and Traumatic Surgery, 1978
Polyethylene in the form of a concave bearing surface at the hip wears very slowly, and clinical and histological evidence suggests that the volume of debris so released is well tolerated. However, significantly greater volumetric wear rates are produced when (1) polyethylene is used as the convex component of a joint and (2) abrasives such as PMMA or ...
