Abstract: Using electrochemical method the Fe-P coating of amorphous alloy was prepared.The effect of different electrodepositional conditions on the composition of phosphrous in alloy had been studied. We determined the corrosive behavior and polarization curve of the amorphous alloy. The results indeca-ted that the alloys in acid solution were rather active at the initial period, the phosphorus in amorphous alloy accelerated the process of corrosion,richened the content of phosphorus on the surface and the alloy turned into a passive state.The crystalline temperature and the hardness of the amorphous electro-depositional coating were determined.
