Differences in the Sliding Wear Track Patterns Between UHMWPE/Steel and UHMWPE/CNx Pairs

, 2012
This work explores the effect of surface modification of stainless steel with a carbon nitride (CNx) film, under sliding wear of the UHMWPE/steel. Wettatibility of CNx coatings is assessed by means of the sessile drop method using two different liquid ...

Thickness Reduction Strategy for Graphite Composite Bipolar Plates: Materials, Structure, and Manufacturing Process

Carbon Neutralization, Volume 5, Issue 3, May 2026.
Schematic diagram of challenges and advanced strategies by CBP after thickness reduction. ABSTRACT The proton exchange membrane fuel cell (PEMFC) converts clean hydrogen's chemical energy into electricity and is vital for carbon neutrality. However, its development is limited by low volumetric power density and high cost.

The effect of accelerated aging on the wear of UHMWPE

Journal of Materials Science: Materials in Medicine, 2001
Oxidative degradation of UHMWPE has been found to be a cause of elevated wear rate of the polymer in total joint replacement leading to failure of these devices. In order to evaluate long term stability of polymers, various accelerated aging methods have been developed.
