| 摘 要： | 采用销盘式试验机对聚四氟乙烯和丁腈橡胶的磨损特性进行了研究。试件浸入水或钻井泥浆中,在不同的正压力和转速下进行试验。在试验中,还采用了固相含量分别为0.02％和0.13％(重量百分比)的两种泥浆。磨损表面用扫描电镜和X射线能谱仪进行了观察。试验结果表明,泥浆的固相含量对高分子材料的湿磨粒磨损起着重要作用,丁腈橡胶在泥浆中的抗磨性比聚四氟乙烯好得多。

| Abstract: | Wearability of polytetrafluoroethlene (PTFE) and nitrile rubber (NRB) were investigated with a disc or pin-disc-type test machine. The specimen was immersed in water or in drilling mud. Wear test were carried out in the conditions of different normal loads, rotating speed and two kinds of drilling mud with solid-phase content 0.02wt% and 0.13wt% respectively. The operation surfaces were examined with scanning electron microscopy (SEM) and X-ray potential spectroscopy (XPS).The test results show that the solid-phase content of drilling mud are the important cause of wet abrasion of polymer and the wear resistance of NRB is much better than that of PTFE in drilling mud. |
