Project Description

Applications are invited to undertake a PhD programme in partnership with Lloyd’s Register Foundation.

Background

“Assurance of coatings” is one of the priorities for future development. A barrier to the application of novel coatings is an understanding of how coatings perform over long durations of time in their operating environment through short- term testing. This barrier is causing severe delays in the uptake of coating solutions available in one market sector to another. The research proposed herein aims to minimise the risk of unexpected coating failure on offshore structures in ambient, arctic and hot subsea environments, and improve understanding of the long-term performance of thermally sprayed coatings from relatively short-term tests.

Project Outline

The first objective of this project is to develop a method of accelerated pre-conditioning to produce a standard, stable coating system so that short-term testing can then be undertaken to measure the stable corrosion rate in response to coating variables such as coating composition, coating microstructure, use of sealants and the introduction of coating defects. The method of accelerated pre-conditioning will investigate the effect of the following factors on the deposition of the calcareous layers. The major focus of the work will be the production of bespoke specimens created in engineered environments by short-term exposure which will simulate the state of a damaged coating exposed to a subsea (arctic, ambient and hot) environment for long periods of time. The second objective of this project is to investigate the effect of coating composition, coating microstructure, use of sealants and the introduction of new coating defects using quantitative electrochemical techniques. The novel accelerated test approach developed in this project will help the understanding of how both existing and new coatings perform over long durations of time in their operating environment through short-term testing. This will further facilitate the industrial uptake of novel coatings in the future.
