Effect of Hot-Rolled Oxide Scale on Dry/ Wet Cyclic Corrosion Behavior of Q370qNH Steel in Simulated Industrial Atmosphere Environment
文献摘要：
The corrosion behavior of Q370qNH steel in the presence and absence of hot-rolled oxide scale in simulated industrial atmospheric environment was studied by dry/wet cycle accelerated corrosion experiments. The experimental results show that the corrosion type of bare steel is uneven overall corrosion and large size pitting corrosion in small areas; that of oxide scale sample is local dissolution corrosion and small size pitting corrosion in large areas, and corrosion rate is much smaller than that of bare steel. The corrosion products of both steels are composed of α-FeOOH, γ-FeOOH, Fe2O3, and Fe3O4, but the formation mechanism is different. The bare steel generates α-FeOOH and γ-FeOOH through "acid regeneration cycle mechanism"; the oxide scale sample generates hydroxides mainly through the gradual dissolution of the oxide film, and then through "the acid regeneration cycle mechanism". With the extension of corrosion time, the electrochemical stability of the sample with oxide scale increases, but the change of tafel curve of bare steel sample is not obvious. In simulated industrial atmosphere, the existence of hot-rolled oxide scale can facilitate the formation of dense rust layer on the surface of Q370qNH steel, which is more protective than bare steel.
