Corrosion inhibition systems, including coated substrates, coating materials and corrosion inhibition compounds, and methods of making the same are disclosed. These systems and methods include corrosion inhibition compounds that are responsive to corrosion at a surface, releasing active inhibitor groups upon a corrosion stimulus. The active inhibitor groups are selected to block corrosion at the surface by inhibiting oxidation reactions, reduction reactions and/or by forming a passivation layer. Corrosion inhibition compounds may be linear polymers that include the inhibitor groups linked together with labile linkages that are disulfide or metal-sulfide bonds.
本发明公开了缓蚀系统,包括涂层基材、涂层材料和缓蚀化合物,以及制造方法。这些系统和方法包括对表面腐蚀有反应的缓蚀化合物,在腐蚀刺激下释放活性抑制剂基团。活性抑制剂基团可通过抑制氧化反应、还原反应和/或形成钝化层来阻止表面腐蚀。缓蚀化合物可以是线性聚合物,其中包括以二硫键或金属硫键等易变连接方式连接在一起的抑制剂基团。
