稀土對鋼耐大氣腐蝕性能的影響

The Effect of Rare Earths on Resistance to Atomospheric Corrosion of Steels

摘要: 采用戶外暴露試驗、周浸法和交流阻抗法測定了稀土對碳鋼(A3)、08CuPv和09CuPTi的耐大氣腐蝕性能,實驗表明,稀土能改善08CuPv和09CuPTi的耐大氣腐蝕性,并隨稀土含量增高,鋼的耐大氣腐蝕性能增強.稀土對碳鋼的耐大氣腐蝕性沒有明顯改善.

Abstract: The effect of RE on atmospheric corrosion resistance of carbon steel(A3),08CuPV and 09CuPTi steel has been investigated by outdoor exposure test,electrochemical alternate immersion test and alternative impedance method. The experimental results show that RE can increase resistance to atmospheric corrosion for 08CuPV and CuPTi, but no influence on carbon steel.
