以氧化铁、铝粉、三氧化钨、石墨为原料，采用自蔓延离心法制备了具有内生强化W2C相的Fe4l涂层。采用X射线衍射仪分析涂层相物相，采用扫描电镜观察涂层组织及磨损后形貌，利用盘销式试验机对比检测了FeAl和Fe3Al/W2C涂层的干摩擦性能。结果表明，反应原料中的铝与石墨比例为2：1时，涂层中的主要物相为w2C和Fe3Al/W2CW2C涂层的相对耐磨性是FeAl涂层的1．6倍。

Fe3A1/W2C coating was fabricated under conditions of self-propagating high-temperature synthesis （SHS） by the raw materials of Fe203, A1, WO3, C. The phases in the coating were examined using X-ray diffraction （XRD）. The microstructures and wear morphology of the coatings were analyzed with scanning electron microscopy （SEM）. Pin on disk tester used for contrast detection FeA1 and Fegkl/W2C coating＇s dry friction and wear behavior. The experimental results show that metallurgical bonding had formed between the coatings and the substrate. The coating, with 2.5 mm thickness, has dense microstructure which was composed of Fel and W2C when the ratio between A1 and C is 2：1. The wear-resistance of FeuM/W2C coating was 1.6 times than that of FerAl coating.
