Corrosion Performance of Chemically Modified Multiwall Carbon nanotube Epoxy-Amine Coating Systems on Steel Substrates

Corrosion Performance of Chemically Modified Multiwall Carbon nanotube Epoxy-Amine Coating Systems on Steel Substrates
Available for download

Carbon nanotubes are well-known for their ability to improve critical properties of polymeric materials. Our research objective is to quantify the influence of incorporating multi-walled carbon nanotubes (MWCNT) modified with amine, hydroxyl, or epoxy functionalities on the corrosion performance of epoxy amine coatings on steel substrates.

Carbon nanotubes are well-known for their ability to improve critical properties of polymeric materials. Our research objective is to quantify the influence of incorporating multi-walled carbon nanotubes (MWCNT) modified with amine, hydroxyl, or epoxy functionalities on the corrosion performance of epoxy amine coatings on steel substrates. Coated substrates were exposed to ASTM B117 for 168 hours and were analyzed via optical imaging as a function of time. After 168 hours, the coatings were removed from the substrate and the substrate/coating interface was investigated by scanning electron microscopy (SEM) - energy dispersive X-ray spectroscopy (EDS). Coatings that contained MWCNTs reduced the rate of corrosion compared to coatings with without MWCNTs, however the corrosion resistance was statistically insignificant between formulations containing MWCNTs. SEM-EDS analysis showed a reduction in the frequency of corrosion products and corrosion-inducing NaCl at the coating/substrate interface of MWCNT formulations compared to without MWCNTs. It is hypothesized that the reduced amount of corrosive species at the coating/substrate interface is attributed to increased ion tortuosity from interactions between the permeating ions and the MWCNTs.

In this paper, failure analysis methodology will be applied to the principal mechanisms by which FBE coatings fail during long term service; with specific application to case studies involving blistering. The case studies apply standard failure analysis techniques to determine the primary causes and modes of failures.

A previous paper presented by the authors at SSPC 2015 demonstrated the futility and folly of attempting to use accelerated corrosion testing as a tool for predicting real world corrosion performance. The effect of corrosion was shown to be governed by the type of ions and the concentration of oxygen in the corrosion environment. By understanding these two factors, accelerated corrosion testing can, however, be used as an indicator of performance which may be encountered in the real world.
