Copper particles embedded into polymer surfaces by cold spray (CS) have been confirmed as a method for antifouling (AF) protection. CS is a low-heat coating process which can be used or employed over large areas. The key parameters that indicate AF potency are particle penetration depth and copper surface coverage. Adaptation of this process towards industrial level requires the process inputs leading to the best outputs to be identified. In this paper, copper particles were deposited onto two polymers used in marine applications with CS, however, without the use of gas-heating hence deposition was free of any additional heat input. Analysis was carried out to determine which process conditions and material properties can lead to most effective AF coating results.
Cold Spray (CS) of copper particles onto polymers has been validated as an effective tool for maintaining surface integrity in bioenvironments. CS requires limited heat input, can be applied locally or in large areas. The key parameters are particle penetration depth and copper surface coverage. However, the process parameters that can optimize the coating performance with deposition have not been comprehensively explored. In this paper, copper particles were deposited onto two polymers used in marine applications. A detailed analysis was carried out to correlate the key surface properties to the process so as to determine the optimum conditions.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
