The melted tungsten carbide would react with the steel matrix on the interface and the reaction zone was observed as a result . the reacting production was examined as fe3w3c by means of x - ray diffraction and scanning electron microscopy analysis . the reaction between tungsten particle and steel matrix could improve the interfacial bonding strength remarkably Wc鋼復(fù)合材料的制備過(guò)程中, wc顆粒在高溫下發(fā)生了局部溶解并在wc顆粒和鋼基體界面處發(fā)生了界面反應(yīng); x射線(xiàn)衍射和電子衍射花樣分析表明,反應(yīng)產(chǎn)物為高穩(wěn)定性的fe _ 3w _ 3c ,界面反應(yīng)有效地改善了wc顆粒與鋼基體的界面結(jié)合。
