在适当的电解液中可使酚及取代酚在钢材的表面进行电聚合,而生成有机涂层。本文作者测试了这些涂层的物理和抗腐蚀性能。在槽液内以胺或表面活化剂为添加剂以促进镀层的均匀性。为了测取电流密度和电解液成份的最佳值,采用了赫尔槽方法。文内还提供了涂层厚度、干燥时间和附着力等物理性能的测定值。并用电桥测定电容和电阻及进行盐雾试验等来评价涂层的抗腐蚀能性。在含有六胺的电解液内酚的聚合可以给出满意的涂层,这种涂层在盐雾试验时的抗腐蚀能力为72小时。
Phenols and substituted phenols can be electropolymerized on the surface of the steel in an appropriate electrolyte to form an organic coating. The authors tested the physical and anticorrosion properties of these coatings. Amines or surfactants are added as additives in the bath to promote the uniformity of the coating. In order to determine the best current density and electrolyte composition, the Hull cell method was used. The article also provides the coating thickness, drying time and adhesion and other physical properties of the measured value. The resistance and corrosion resistance of the coating was evaluated by measuring the capacitance and resistance with a bridge and performing a salt spray test. Polymerization of phenol in the electrolyte containing hexamine gives a satisfactory coating with a corrosion resistance of 72 hours in a salt spray test.
