中文摘要：

采用热压成型法制备氧化锌晶须（ZnOw）填充PA1010复合材料，在牵引滚动摩擦磨损试验机上研究复合材料的滚动牵引摩擦磨损性能，采用光学显微镜和扫描电子显微镜观察分析磨损表面及其转移膜形貌．结果表明：复合材料的牵引力系数、蠕滑比和磨损量随牵引负荷增加而升高；在同一牵引负荷条件下，蠕滑比和磨损量随ZnOw含量增加先降低而后增加，当ZnOw含量为10％和15％时，复合材料的蠕滑比和磨损量较低；尼龙基体的主要磨损机理为严重的塑性流动和基体溃裂，并伴有轻微粘着；当ZnOw含量为10％和15％时，犁沟是复合材料的主要磨损机制，同时在偶件表面形成了结构致密的转移膜；填充20％ZnOw的复合材料的磨损表面出现表层脱落，同时在偶件表面形成层状转移膜．

英文摘要：

Nylon1010 composites filled with zinc oxide whisker （ZnOw） were prepared by hot squeeze method. Tractive rolling tribological behavior of composites was studied with a self-made tester. The results indicat that, coefficients of traction of composites were increased by tractive load, but they were less influenced by the content of ZnOw. They fluctuated from 0.09 to 0.10 for 0.75 Nm tractive load and from 0.16 to 0.20 for 1.0 Nm tractive load respectively. Creep ratio and wear volume loss were increased with increasement of tractive load. Under the same tractive load, creep ratio and wear volume loss decreased with increasing of the content of ZnOw until it reached about 10% - 15%, then they both increased with the content of ZnOw. Under the two tractive loads, creep ratio of 15% ZnOw-PA was about 10% of that of pure nylon. Wear volume loss of composites decreased about 70% of that of pure nylon. Plastic flow and matrix break were the main wear mechanisms of pure nylon. For the composites filled with 10% and 15% ZnOw, ploughing was the main wear mechanism, and the transfer film with compacted structure formed on the counter pair. Delamination occurred on the worn surface and transfer film of 20% ZnOw-PA.
