Abstract

Corrosion is a leading challenge that engineers and researchers face when working in marine environments. Annually, corrosion costs an estimated $2.5 trillion globally and can lead to environmental damage and pose a threat to public safety. This thesis investigates the effects of crevice corrosion on the performance of different epoxy adhesives when mated with stainless steel to determine if using epoxy is a viable option for the development of systems operating in marine environments. To accomplish this, metal-to-metal lap shear samples were created using Araldite 2015-1, Plexus MA560-1, Plexus MA310, and Plexus MA8120 epoxies and different preparation methods. These samples were deployed in a natural marine environment for up to 6 months before bond strength and visible corrosion were assessed. While the samples with Araldite 2015-1 experienced the least amount of corrosion, with most bonds failing at 6 months, replication of the work done in this paper for real marine applications is discouraged.
