Abstract

Abstract The article presents the results of the preliminary research of tribological properties of flame sprayed nickel and aluminum coatings reinforced with carbon nanotubes made on the structural steel S235J0 substrate. The carbon material – carbon nanotubes Nanocyl NC 7000 (0.5 wt.% and 1 wt.%) was used for structural reinforcement. The properties evaluation was made by the use of optical microscopy, scanning electron microscopy, Raman spectroscopy, microhardness measurements, and by means of abrasion and erosion resistance laboratory tests. The obtained results were compared with pure nickel powder coatings 2N5 (Ni 99.5%) and with pure aluminum powder coatings (EN AW 1000 series). It was proved that the flame spraying of nickel and aluminum coatings reinforced with particles carbonaceous material can be an effective alternative for other more advanced surfacing technology. The preliminary test results will be successively extended by further experiments to contribute in the near future to develop innovative technologies, that can be implemented in the aviation industry and the automotive. The presented research is a continuation of the work previously published.
碳纳米管颗粒增强火焰喷涂涂层的性能研究
摘要本文介绍了在S235J0结构钢基体上制备的碳纳米管增强镍铝火焰喷涂涂层摩擦学性能的初步研究结果。采用碳材料——碳纳米管Nanocyl NC 7000 (0.5 wt.%和1 wt.%)进行结构加固。通过光学显微镜、扫描电子显微镜、拉曼光谱、显微硬度测量以及实验室磨损和耐蚀性测试对其性能进行了评价。将所得结果与纯镍粉末涂料2N5(镍含量99.5%)和纯铝粉末涂料(EN aw1000系列)进行了比较。结果表明,颗粒碳质材料增强镍铝涂层的火焰喷涂技术可作为其他先进堆焊技术的有效替代方法。初步测试结果将通过进一步的实验逐步扩展,以便在不久的将来开发可在航空工业和汽车中实施的创新技术。提出的研究是先前发表的工作的延续。
