| 摘 要： | On the SEM micrographs of Ti implanted H13 steel, a tree-branch-like structure can be observed. Further investigation with TEM shows that the newly tormed composition is a formation of nann-meter FeTi_2 phase in Ti implanted layer. The layer with a relatively high corrosion resistance has been formed in Ti implanted H13 steel with this structure.The results of electrochemical measurement show that the corrosion current density decreases obviously with an increase of ion dose. The corrosion current density in Ti implanted steel with a dose of 1.3×10~(18)/cm~2 is 8-20 times less than that of Ti implanted steel with a dose of 6×10~(17)/cm~2. The corrosion behavior of Ti implanted steel with a dose of 6×10~(17)/cm~2 could be further improved as the sample was annealed at 500℃ for 20 min and the corrosion current density decreases by 48-80 times compared to that of non-implanted samples. The corrosion trace was not observed on the annealing sample by SEM, after multi-sweep cyclic voltammetry of 40 cycles

| Abstract: | On the SEM micrographs of Ti implanted H13 steel, a tree-branch-like structure can be observed. Further investigation with
TEM shows that the newly formed composition is a formation of nano-meter FeTi2 phase in Ti implanted layer. The layer with a relatively high corrosion resistance has been formed in Ti implanted H13 steel
with this structure. The results of electrochemical measurement show that the corrosion current density decreases obviously
with an increase of ion dose. The corrosion current density in Ti implanted steel with a dose of 1.3×1018/cm2 is 8–20 times less than that of Ti implanted steel with a dose of 6×1017/cm2. The corrosion behavior of Ti implanted steel with a dose of 6×1017/cm2 could be further improved as the sample was annealed at 500°C for 20 min and the corrosion current density decreases by 48–80
times compared to that of non-implanted samples. The corrosion trace was not observed on the annealing sample by SEM, after
multi-sweep cyclic voltammetry of 40 cycles were performed. This indicates that terrific corrosion resistance can be obtained
after annealing for Ti implanted sample.
