Rare Metals, Volume 42, Issue 9, Page 3114-3129, September 2023., 2023 Graphic Abstract Abstract Electrochemical tests and surface analysis were applied to study the corrosion behavior and passive film characteristics of three‐dimensional‐printed NiTi shape memory alloys fabricated by laser‐powder bed fusion (L‐PBF) in artificial saliva at 37 °C. The passivity of L‐PBF NiTi shows to be influenced by the process parameters

Gongye shui chuli, 2009 针对中央空调冷却水循环系统中的腐蚀问题,进行了单独投加臭氧、单独投加缓蚀剂、臭氧及缓蚀剂联合使用三种情况下对空调冷却水的缓蚀试验研究。结果表明,臭氧单独作用时,腐蚀速率为0.14~0.26 mm/a,缓蚀率为25%~55%。臭氧与钼酸钠共同作用时,碳钢的腐蚀速率小于0.16 mm/a,缓蚀率大幅度提高,两者有很好的协同作用。
