An effective barrier coating aims to minimize exposed surface area. A sacrificial layer requires a large exposed surface.to maintain long term protection of the substrate. This work is to investigate this synergy in order to elucidate the factors that have the greatest influence over the corrosion protection properties and failure modes of TSN.
Nanoparticles are being considered in the development of durable coating systems due to their beneficial electrical and mechanical properties. The present study aims to investigate the corrosion performance of a nanoparticle enriched zinc rich primer (NPE-ZRP) for structural steel in aggressive marine exposure.
Chemically Bonded Phosphate Ceramic coating was investigated in various environments such as inland, beach and salt-fog exposure. After 8-month outdoor testing, the coating was evaluated by visual inspection, coating thickness, adhesion measurement and X-ray diffraction. Long term testing ensued, up to 24 months.
Fitness for purpose of low temperature cure liquid-applied coating systems for pipeline maintenance and repair. Potential revisions to incorporate low temperature cure liquid-applied coating products into Table 1 of CSA Z245.30-14 will be presented along with commentary related to the deviations from the standard.
