某些金属材料的结构性能,对腐蚀损失极为敏感。如,作为磁盘及磁头的磁薄膜材料,在磁记录应用上有着非常重要作用的Co制品,就是如此。为此,人们往往采用缓蚀剂来处理Co制品。缓蚀剂的缓蚀作用,可以不同程度地减少或延缓Co制品的腐蚀损失。 但是,目前许多推荐使用的缓蚀剂,对Co制品的保护极为有限,一旦把Co制品脱离含 The structural properties of certain metallic materials are extremely sensitive to corrosion losses. This is the case for the magnetic thin film materials used as magnetic disks and heads, and Co products, which play a very important role in magnetic recording applications. To this end, people often use corrosion inhibitors to deal with Co products. Corrosion inhibitor corrosion inhibition, to varying degrees, reduce or delay the corrosion loss of Co products. However, at present, many recommended corrosion inhibitors have very limited protection of Co products. Once the Co products are removed from the
