摘 要：<正>The corrosion behavior of ZL104 alloy at different states （as-cast and heat treatment） in salt spray corrosion （SSC） was studied. The results show that the sample treated after refinement and modification has the least corrosive resistance compared with the sample bearing as-cast structure at the beginning of the corrosion. As the corrosion process continued, however, the trend reversed itself. After 44 h continuous corrosion, the corrosive rates of all samples tend to be stable. After experiments, the sample bearing as-cast structure had the most corrosive products on the surface whereas the sample being refined and modified had the least products. The Fourier transformation infrared spectroscopy （FTIR） analyses of the corrosion products show that these products are composed of hydroxyl-containing substances.
