用连续电流法研究了香豆素对氯化物镀锌层的影响。用扫描电子显微镜(SEM)分析了沉积层的形貌。并对矿床的择优取向进行了探讨。在J=4A/dm(2)时，未加添加剂的锌在香豆素存在下的(112)织构转变为(110)织构。通过阳极极化曲线、极化电阻(R-p)测量和失重研究，研究了其在3.5%氯化钠溶液中的腐蚀行为。采用香豆素作为添加剂，提高了镀锌层的耐蚀性。(C)2006爱思唯尔B.V.保留所有权利。
Continuous current was used to study the effect of coumarin on zinc deposits from chloride bath. Scanning electron microscopy (SEM) was used to analyze the morphology of the deposits. The preferred orientations of the deposits were also investigated. At J=4 A/dm(2) the (112) texture of zinc electrodeposited without additive changes to a (110) texture in presence of coumarin. The corrosion behaviour was investigated in aerated 3.5% NaCl solution as well as under anodic polarization curves, polarization resistance (R-p) measurements and weight-loss studies. The corrosion resistance of zinc deposits was improved by the use of coumarin as additive. (c) 2006 Elsevier B.V. All rights reserved.
