摘要
研究了Fe含量在 0 .0 5 %～ 0 .2 0 % (质量分数 )范围内对Ti— 5 0 0合金的焊接和腐蚀性能的影响。结果表明 :Fe含量在 0 .0 5 %～ 0 .2 0 %范围时 ,Ti— 5 0 0合金具有良好的焊接性能 ,焊缝具有很强的腐蚀抗力 ;Ti— 5 0 0合金在沸腾 8MHNO3溶液中的腐蚀率小于 0 .1mm/y ,溶液中添加Ru3+ 、Cr6+ 、Ce4 +
Effects of different Fe contents from 0.05wt% to 0.2wt% on the welding and corrosion resistance properties of Ti 500 alloy were investigated.Experimental results showed that,with Fe contents from 0.05 wt% to 0.2 wt%,Ti 500 alloy possessed good welding properties.The welds showed great corrosion resistance.The corrosion rate of Ti 500 was less than 0.1mm/y in boiling 8M HNO 3 solution. The corrosion resistance of Ti 500 could be improved significantly by adding Ru 3+ , Cr 6+ and Ce 4+ into the solution.
