Effect of Surface Crosslinking on the Wear and Friction Behavior of Tea Polyphenol Stabilized Ultra-High Molecular Weight Polyethylene for Total Joint Replacements [PDF]

open access: yesMaterials Research
Highly crosslinked ultra-high molecular weight polyethylene (UHMWPE) with vitamin E (VE) as an antioxidant is widely used for joint implants. VE helps resist oxidation but raises concerns about reduced crosslink density and wear performance.

Impulse-driven surface breakdown data : a Weibull statistical analysis [PDF]

open access: yes, 2012
Surface breakdown of oil-immersed solids chosen to insulate high-voltage, pulsed-power systems is a problem that can lead to catastrophic failure. Statistical analysis of the breakdown voltages, or times, associated with such liquid-solid interfaces can ...

Fabrication of well-miscible and highly enhanced polyethylene/ultrahigh molecular weight polyethylene blends by facile construction of interfacial intermolecular entanglement

open access: yesPolymer Testing, 2021
To enhance the interfacial intermolecular entanglement of the polyethylene/ultrahigh molecular weight polyethylene (PE/UHMWPE) system, the blend was fabricated via a facile melt blending process in presence of UHMWPE with relatively low molecular weight (

Improving the surface properties of an UHMWPE shoulder implant with an atmospheric pressure plasma jet [PDF]

open access: yes, 2018
Insufficient glenoid fixation is one of the main reasons for failure in total shoulder arthroplasty. This is predominantly caused by the inert nature of the ultra-high molecular weight polyethylene (UHMWPE) used in the glenoid component of the implant ...

Which Design and Biomaterial Factors Affect Clinical Wear Performance of Total Disc Replacements? A Systematic Review [PDF]

open access: yes, 2014
Background Total disc replacement was clinically introduced to reduce pain and preserve segmental motion of the lumbar and cervical spine. Previous case studies have reported on the wear and adverse local tissue reactions around artificial prostheses ...

Load-Dependent Frictional Performance of Vitamin E-Blended Ultrahigh Molecular Weight Polyethylene in Serum Lubricant

open access: yesTribology Online, 2010
The load-dependent frictional performance of vitamin E-blended ultrahigh molecular weight polyethylene (UHMWPE) in serum lubricant was examined. The UHMWPE specimens were slid against the surface of Co-28Cr-6Mo alloy by using a pin-on-disk friction test ...

Wear Tests of a Potential Biolubricant for Orthopedic Biopolymers [PDF]

open access: yes, 2015
Most wear testing of orthopedic implant materials is undertaken with dilute bovine serum used as the lubricant. However, dilute bovine serum is different to the synovial fluid in which natural and artificial joints must operate. As part of a search for a

Mechanical Interaction between Vitamin E-Containing Ultrahigh Molecular Weight Polyethylene and Co-28Cr-6Mo Alloy in Water

open access: yesJournal of Biomechanical Science and Engineering, 2009
The mechanical interaction between ultrahigh molecular weight polyethylene (UHMWPE) and a Co-28Cr-6Mo alloy in water was examined in order to clarify the wear resistance mechanism of vitamin E-containing UHMWPE in knee prostheses.
