Abstract
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.
