Investigation of the factors affecting the strength of a metal-rubber interface joined by vulcanization: a review

Abstract

Metal-rubber parts are used in many sectors because of their ability to combine the advantages of both rubber and metals. Thanks to the advances acquired as a result of the studies carried out by researchers and industries, the usage area of metal-rubber parts expands day by day. The focus of researchers in this field continues to be on achieving effective joints, improving their durability, and ensuring their preservation, as these composites find wide-ranging use. In particular, the positive effects of newly developed surface treatments and adhesive materials on bond strengths have been observed in recent years. Within the scope of this study, the metal-rubber bonding mechanism, vulcanization, bonding during/after vulcanization, some standards related to rubber, bond failures, and their causes are investigated. This review focuses on studies addressing the factors influencing the interfacial strength of metal-rubber bonds joined by vulcanization. Additionally, it provides information on studies and their findings up to date regarding the effects of vulcanization parameters, corrosive environments, components in the bonding process, and different substrates on the bond strength.
