摘要
钛合金广泛应用于航空航天、海事、军事等领域,但其较差的摩擦学特性限制了它在精密零部件中的应用。因此,研究适用于钛合金高精密成形加工过程中的润滑添加剂是实现钛合金高效加工的关键。采用相转移法制备了氧化石墨烯和黑磷纳米片复合油基润滑添加剂,通过扫描电子显微镜、拉曼光谱仪和X射线衍射仪等对复合添加剂的形态、组成和物相结构进行了表征,利用UMT-5多功能摩擦磨损试验机评价了黑磷-氧化石墨烯纳米片作为液体石蜡基润滑添加剂在钛合金表面的摩擦学性能。实验结果表明,黑磷纳米片与氧化石墨烯的质量比为1∶4的复合润滑剂表现出最佳的综合摩擦学性能,综合测试分析证实,黑磷-氧化石墨烯复合润滑添加剂的优异摩擦学性能归因于吸附与摩擦化学反应的协同作用。该发现对开发用于钛合金制造和加工的新型润滑剂具有指导意义。
Titanium alloys are widely used in aerospace,maritime,military and other fields,but their poor tribological properties limit their application in precision parts.Therefore,the study of lubricants suitable for the high precision forming process of titanium alloys is the key to achieve efficient machining of titanium alloys.In this study,graphene oxide(GO)and black phosphorus(BP)nanosheets composite oil-based lubrication additives were prepared by phase transfer method.The morphology,composition and phase structure of the composite additives were characterized by scanning electron microscope,Raman spectrometer and X-ray diffractometer.The tribological properties of BP-GO nanosheets as liquid paraffin-based lubrication additives on titanium alloy surfaces were evaluated using a UMT-5 multifunctional friction and wear testing machine.The experimental results showed that the composite lubricant with a 1∶4 mass ratio of BP nanosheets to GO exhibited the best tribological performance.Comprehensive test analysis confirmed that the excellent tribological properties of BP-GO composite lubrication additives were attributed to the synergistic effect of adsorption and tribological chemical reactions.This finding provides guidance for developing new lubricants for the fabrication and processing of titanium alloys.
