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, 2003 用点蚀电位法和失重法评价了七种阻垢缓蚀剂在不同冷却水样中对不锈钢的缓蚀效果。用腐蚀失重法评价阻垢缓蚀剂对不锈钢的缓蚀效果，既不合理也很难测准。点蚀电位法是评价阻垢缓蚀剂对不锈钢缓蚀效果的有效方法，但要选择合适的空白水样。

Gongye shui chuli, 1998 讨论了冷却水系统各种常用缓蚀剂在采暖水系统软化水中的缓蚀作用，除钼酸盐、葡萄糖酸盐、羧-磺盐共聚物少数几种外，其余的需要通过Ca2+、Mg2+、OH-等水中离子参与成膜才能起缓蚀作用的缓蚀剂不宜在软化水中使用，一些酸性介质缓蚀剂对软化水有很好的缓蚀作用。自制的MYN系列软化水缓蚀剂，只要控制Na2MoO4的浓度在15mg/L左右就对软化水有极好的缓蚀作用，该缓蚀剂具有成本低，缓蚀效果好，适应水质范围宽，操作控制弹性大等特点。
