摘要
研究了高强亚稳β型钛合金TB 19的均匀腐蚀性能、耐冲刷腐蚀性能及应力腐蚀性能。结果表明,TB 19合金在60°C海水中经1000h均匀腐蚀试验后基本无腐蚀;在10m/s流速天然海水中,冲刷腐蚀速度仅为0.00029mm/a;在海水中的应力腐蚀强度因子为55.15MPa·m1/2,证明TB 19合金是一种耐蚀性能优良的高强钛合金。
The corrosion behavior in seawater of high strength titanium alloy TB-19 forgings is investigated.The results manifest that the alloy prove resistant to seawater with an erosion rate 0.00029mm/a in the 10m/s flow and an stress corrosion factor 55.15MPa·m^(1/2) remaining uncorroded after 1000h uniform corrosion test in 60℃ seawater.
