Investigations on the tribological properties, i.e., abrasion resistance, friction coefficient, and wear of water conditioned polyamide6/hexagonal boron nitride composites were carried out in this research. Polyamide6 and polyamide6/hexagonal boron nitride composites were fabricated with the help of a twin-screw extruder and injection moulding machine. Fabricated materials were water immersed for 15 days to analyse the effect of water absorption on the tribological properties of materials. Tribological tests were carried out on a pin-on-disc tribometer, and abrasion resistance tests were performed on a TABER abrader. The SEM analysis was carried out to analyse the wear tracks of water conditioned composites. Testing on TABER abrader revealed the loss in abrasive resistance of composite materials, while tribological testing of composites with steel as the other mating and rubbing surface revealed improvements in COF and wear after water absorption. The SEM images revealed less depth of wear in water conditioned materials compared to dry ones. The causes of wear were found as the stick and slip, i.e., adhesive wear in which material tends to stick during matting with steel disc, and due to the continuous movement, it slips. Water absorption was found supportive in the formation of smooth lubricating transfer film on a steel disc. Bonding between the polyamide matrix and water molecules plus the formation of boric oxide & orthoboric acid were found advantages in decreasing the friction coefficient and wear of water conditioned composites.

本研究对水处理的聚酰胺6/六方氮化硼复合材料的摩擦学性能，即耐磨性、摩擦系数和磨损进行了研究。聚酰胺6和聚酰胺6/六方氮化硼复合材料是在双螺杆挤出机和注塑机的帮助下制造的。将制造的材料浸入水中 15 天，以分析吸水率对材料摩擦学性能的影响。摩擦学测试在针盘式摩擦计上进行，耐磨性测试在 TABER 研磨机上进行。进行SEM分析以分析水处理复合材料的磨损轨迹。对 TABER 研磨机的测试揭示了复合材料的耐磨性下降，而以钢为另一个配合和摩擦表面的复合材料的摩擦学测试表明，吸水后的摩擦系数和磨损有所改善。SEM 图像显示，与干燥材料相比，水处理材料的磨损深度更小。磨损的原因被认为是粘滑，即粘着磨损，材料在与钢盘磨合时容易发生粘连，并由于连续运动而发生滑移。发现吸水有助于在钢盘上形成光滑的润滑转移膜。发现聚酰胺基体与水分子之间的结合以及氧化硼和原硼酸的形成在降低水处理复合材料的摩擦系数和磨损方面具有优势。SEM 图像显示，与干燥材料相比，水处理材料的磨损深度更小。磨损的原因被认为是粘滑，即粘着磨损，材料在与钢盘磨合时容易发生粘连，并由于连续运动而发生滑移。发现吸水有助于在钢盘上形成光滑的润滑转移膜。发现聚酰胺基体与水分子之间的结合以及氧化硼和原硼酸的形成在降低水处理复合材料的摩擦系数和磨损方面具有优势。SEM 图像显示，与干燥材料相比，水处理材料的磨损深度更小。磨损的原因被认为是粘滑，即粘着磨损，材料在与钢盘磨合时容易发生粘连，并由于连续运动而发生滑移。发现吸水有助于在钢盘上形成光滑的润滑转移膜。发现聚酰胺基体与水分子之间的结合以及氧化硼和原硼酸的形成在降低水处理复合材料的摩擦系数和磨损方面具有优势。由于连续运动，它会滑动。发现吸水有助于在钢盘上形成光滑的润滑转移膜。发现聚酰胺基体与水分子之间的结合以及氧化硼和原硼酸的形成在降低水处理复合材料的摩擦系数和磨损方面具有优势。由于连续运动，它会滑动。发现吸水有助于在钢盘上形成光滑的润滑转移膜。发现聚酰胺基体与水分子之间的结合以及氧化硼和原硼酸的形成在降低水处理复合材料的摩擦系数和磨损方面具有优势。
