摘要: The corrosion test was performed for ferritic/martensitic steel HCM12A with and without Fe-Al alloy coating in LBE at temperatures of 550 650°C under loading an immersion time up to 500 h. After the 550°C h, both uncoated Fe-Al-coated showed a good resistance influence tensile stress on corrosion. On other hand, after 650°C, layer specimen surface exhibited no dissolution because formation stable oxide protection film surface, although cracked. penetrated into cracks corroded base metal precoating layer. double layers FeO Fe- Cr spinel. damaged bent zone by stress, Fe-Cr spinel not destroyed cracking stress. did have large in...
