Crosslinking has been extensively introduced to reduce the wear of UHMWPE. In this study the wear rates and wear surfaces of UHMWPE with different levels of crosslinking were compared in a hip joint simulator. The UHMWPE was either non-irradiated, gamma irradiated in air (2.5MRad), or highly crosslinked (7.5 and 10MRad). The intentionally crosslinked materials showed a significantly lower volum...

Wear is a complicated phenomenon caused by the relative movement of two contacting surfaces compressed together by a normal force. Prediction of the wear, in most cases, requires various experiments and microstructural characterization of the contacting surfaces. Mathematical models based on physical concepts could provide considerable help in understanding the physical behavior and hence the p...

Artificially fabricated surface textures can significantly improve the friction and wear resistance of a tribological contact. Recently, this surface texturing technique has been applied to polymer materials to improve their tribological performance. However, the wear behavior of textured tribo-pairs made of steel and polymer materials has been less thoroughly investigated and is not well under...

350 The excessive differential wear of teeth and restorative materials has significant deleterious effects on the biologic, functional, and esthetic condition of the masticatory system. However, controlled investigations of numerous factors that might influence tooth and restoration wear have been mainly laboratory studies, the findings of which might not correlate with either the physical prop...

Influence of initial surface roughness on friction and wear processes under fretting conditions was investigated experimentally. Rough surfaces (Ra=0.15-2.52 μm) were prepared on two materials: carbon alloy (AISI 1034) and titanium alloy (Ti-6Al-4V). Strong influence of initial surface roughness on friction and wear processes is reported for both tested materials. Lower coefficient of friction ...

Glass fiber reinforced plastic composite materials are finding increased applications due to their excellent properties. Fiber reinforced plastic (FRP) composite materials comprise soft matrix and fiber elements. This article presents the tribological aspects of glass fiber reinforced plastic composites. The wear test is carried out for FRP in a pin-on-roller wear tester. The wear rate obtained...

Manufacturers of dental composites promote their products as having ideal wear resistant characteristics. Evaluation of the problems that persist with wear of dental composites is made. Recommendations for further research involving wear resistance of dental composite materials are provided. This article provides a review of English, peer-reviewed literature involving wear resistance of dental ...
