摘要: Abstract Corrosion behavior of two different low alloy steels (specimen 1, specimen 2) coupling to titanium (Ti) was studied in simulative deep-sea environment with 500 m depths. Immersion tests revealed that the corrosion rate 1 higher than 2. The micro morphology showed all specimens steel susceptible both intergranular and pitting corrosion. Electrochemical results imply galvanic current bigger 2, then decreased stabilized at a small range after 15 h correspond. Finite element method constructed explain development density distribution distance electrodes. resistance followed order: 2 > specimen when Ti alloy.
