The present work discusses the comparative wear behavior of composite (amorphous/nanocrystalline) blast furnace pig iron coatings deposited on a mild steel substrate using high velocity oxygen fuel and air plasma spray techniques. The study has been carried out using a ball-on-disk tribometer with the coated specimen and tungsten carbide ball as disk and counter body, respectively. A composite structure, consisting of both amorphous and nanocrystalline phases, has been confirmed by x-ray diffraction and transmission electron microscopy. It has indicatively been shown that the wear resistance of the mild steel substrate could be improved using composite coatings due to the higher micro-hardness of the coatings. Indirect tribo-oxidation involving oxidized debris has been found to be the dominant wear mechanism.

半结晶 HVOF 和等离子喷涂富磷生铁涂层的比较磨损行为

目前的工作讨论了使用高速氧燃料和空气等离子喷涂技术沉积在低碳钢基材上的复合（非晶/纳米晶）高炉生铁涂层的比较磨损行为。该研究是使用球盘摩擦计进行的，涂层试样和碳化钨球分别作为盘和反体。X 射线衍射和透射电子显微镜证实了由非晶相和纳米晶相组成的复合结构。已经表明，由于涂层具有更高的显微硬度，使用复合涂层可以提高低碳钢基材的耐磨性。已发现涉及氧化碎片的间接摩擦氧化是主要的磨损机制。
