摘要

采用高强度钢丝进行径向加固的轮胎需要在橡胶和钢之间形成粘合。目前脐带上的黄铜涂层用于促进结合，但随着时间的推移会发生劣化，最终会发生底层钢的腐蚀。锌钴涂层已被用作黄铜的替代品。只要钴含量为1.5wt%，这些涂层就能够在脐带制作操作中拉伸。硫化后的拉出试验表明，锌钴镀层的粘附强度与黄铜镀层相似。在温暖潮湿的条件下老化16天后，锌钴涂层保持了比黄铜更高的附着力。在轮胎试验中，锌钴涂层在防止钢的红锈形成方面表现优异

Use of Zinc Alloy Coatings on Steel Cord Reinforcement in Vehicle Tyres

SUBJECTTyres which are radially reinforced with high tensile steel cords need to develop a bond between the rubber and the steel. Brass coatings on the cord are currently used to promote the bond but deterioration takes place with time and corrosion of the underlying steel occurs eventually. Zinc-cobalt coatings have been used as a replacement for brass. These coatings are capable of being drawn in the cord making operation provided that the cobalt content is 1.5wt%. Pull-out tests after vulcanising show that zinc-cobalt promotes similar adhesive strengths to that achieved with brass coatings. After ageing in warm moist conditions for up to 16 days the zinc-cobalt coating maintained higher levels of adhesion than brass. In tyre tests the zinc-cobalt coatings were superior in preventing red rust formation on the steel

期刊介绍： Transactions of the Institute of Metal Finishing provides international peer-reviewed coverage of all aspects of surface finishing and surface engineering, from fundamental research to in-service applications. The coverage is principally concerned with the application of surface engineering and coating technologies to enhance the properties of engineering components and assemblies. These techniques include electroplating and electroless plating and their pre- and post-treatments, thus embracing all cleaning pickling and chemical conversion processes, and also complementary processes such as anodising. Increasingly, other processes are becoming important particularly regarding surface profile, texture, opacity, contact integrity, etc.
