摘要

镁合金的缺点是电负性高,耐腐蚀性低。提高镁合金耐腐蚀性能最有效的方法之一是在镁合金表面形成转化胶粘剂涂层,然后再涂漆材料。在对镁及其合金进行染色之前,彩色涂料被广泛用作油漆表面的附着层。近年来,在世界各国的实践中,作为镁及其合金表面铬酸盐层的替代品,纳米级转化钛和/或含锆和含铈的粘接涂层已被广泛应用。本文的工作是致力于开发生产这些涂层的技术。结果表明,制备的AZ31B镁合金钝化涂层在耐蚀性能和防护性能上可与铬酸盐涂层相媲美。研究结果表明,与含铬酸盐的涂层相比,含铬酸盐的涂层对基体的粘附强度更高。

DEVELOPMENT OF CHROMATE-FREE PASSIVATION PROCESSES FOR MAGNESIUM ALLOY AZ31B
The disadvantage of magnesium alloys is their low corrosion resistance due to high electronegativity. One of the most effective methods to improve the corrosion resistance of magnesium alloys is to form a conversion adhesive coating on their surface, followed by applying paintwork materials. Chromatic coatings are widely used as adhesion layers under the paintwork before staining magnesium and its alloys. In recent years, in world practice, as an alternative to chromate layers on magnesium and its alloys, nanoscale conversion titanand/or zirconiumcontaining, and cerium-containing adhesive coatings have been used. The present work is devoted to the development of the technology for producing these coatings. It has been established that the developed passivating coatings based on the AZ31B magnesium alloy are comparable with chromate coatings in terms of corrosion resistance and protective ability. It has been established that coatings with developed adhesive sublayers have a higher adhesion strength to the base compared to coatings with chromate adhesive sublayer.
