一种新型超高强度钢的耐蚀性研究

Research on CorrosionResistance of a New Ultra-high Strength Steel

通过中性盐雾实验和电化学实验对一种新型超高强度钢进行耐腐蚀性能研究。研究表明,与两种传统的超高强度钢A100钢和300M钢相比,新型超高强度钢的自腐蚀电位高,阻抗模值大,在NaCl溶液中抵抗腐蚀的能力强,因而新型超高强度钢的耐腐蚀性能最强。

The corrosion resistance of the steel is researched by neutral salt spray test and electrochemical experiment.It can be found that compared with the traditional ultra-high strength A100 and 300M steels,the new ultra high strength steel has the best corrosion resistance,with higher self-corrosion potential,bigger impedance modulus and stronger resistance to corrosion in NaClsolution.
