A series of composites of UHMWPE filled with various amounts of Titanium (Ti) particles in micron and nano-sizes was developed to explore the possibility of enhancing wear performance. Mechanical properties such as tensile strength, impact strength, Young’s modulus and % elongation showed significant improvement with an increase in Ti particles up to certain amount followed by a decline. Tribological properties were evaluated in a single-pass abrasive wear mode using a pin on disc configuration. The wear resistance of UHMWPE showed significant improvement up to a certain amount of particles. The coefficient of friction also reduced drastically. Vickers and Scratch hardness tests were carried out using diamond indenter. X-ray tomography was done to analyze the dispersion of particles in the matrix. Wettability studies and worn surface analysis were done on the composite- surfaces. Incorporation of Ti particles improved the strength of the composites significantly. The composites ...

钛纳米和微粒与UHMWPE的复合材料,可增强性能

开发了一系列的UHMWPE复合材料,其中填充了各种数量的微米和纳米尺寸的钛(Ti)颗粒,以探索提高耐磨性能的可能性。力学性能,例如拉伸强度,冲击强度,杨氏模量和伸长率%显示出显着改善,其中Ti颗粒增加至一定量,然后下降。摩擦性能通过使用盘式销钉的单次磨料磨损模式进行评估。UHMWPE的耐磨性在达到一定数量的颗粒后显示出明显的改善。摩擦系数也大大降低。使用金刚石压头进行维氏和划痕硬度测试。进行X射线断层扫描以分析颗粒在基质中的分散。在复合材料表面上进行了润湿性研究和磨损表面分析。掺入钛颗粒可显着提高复合材料的强度。复合材料...
