摘要
To explore the compatibility between the new mixture of low melting point fused quaternary nitrate-nitrite prepared in our laboratory and stainless steels in concentrating solar power system,the dynamic corrosion experiment of 304 stainless steel during 1000 h is carried out at 565 ℃ and the flow rate of 0.6,1.3 and 2.0 m/s,respectively. The experimental results show that the oxidation corrosion of 304 stainless steel occurs at three flow rates. Corrosion weight loss(mmass) increases with the increasing corrosion time,and the change law is closer to the parabolic relationship. Meanwhile,the varied flow rates had obvious effects on corrosion behaviors. In addition,the increase in flow rate had no significant effects on the types of oxidation products. © 2023 Science Press.
