Abstract

The main objective of this study is to perform an abrasive wear resistance study of UMHWPE and XLPE by using different grades of abrasive paper (grade 100 (190 µm), grade 220 (50 µm), and grade 400 (40 µm)) with minor (10 N) and major (15 N) loading conditions. In this article, wear performance of the UMHWPE and XLPE materials compared to the bio-tribological data as reported earlier in the clinical studies has been investigated. The experimental result shows that the loss of materials for the XLPE was much higher than the UHMWPE under similar loading conditions. UHMWPE shows a 34% reduction in wear at minor loading conditions and a 53% reduction in wear at major loading conditions. From experimental results it was concluded that Cross-link PE has better wear resistance than UHMWPE in minor wear conditions, whereas UHMWPE shows better wear resistance under major loading conditions. Based upon these results, UHMWPE and XLPE have been recommended for use as bearing materials in orthopedics. The experimental results of this study were validated using results from the available literature.

摘要

本研究的主要目的是通过使用不同等级的砂纸（100号（190微米）、220号（50微米）和400号（40微米）），在较小（10牛）和较大（15牛）载荷条件下，对超高分子量聚乙烯（UMHWPE）和交联聚乙烯（XLPE）进行耐磨性能研究。在本文中，已对UMHWPE和XLPE材料的磨损性能与临床研究中先前报道的生物摩擦学数据进行了比较研究。实验结果表明，在相似载荷条件下，XLPE的材料损失远高于UHMWPE。UHMWPE在较小载荷条件下磨损减少34%，在较大载荷条件下磨损减少53%。从实验结果得出结论，交联聚乙烯在轻微磨损条件下比超高分子量聚乙烯具有更好的耐磨性，而超高分子量聚乙烯在较大载荷条件下表现出更好的耐磨性。基于这些结果，推荐将UHMWPE和XLPE用作骨科的轴承材料。本研究的实验结果通过现有文献的结果进行了验证。
