Multi-scale corrosion assessment of additively remanufactured metallic components used in flow equipment

The EPSRC Centre for Doctoral Training in Future Fluid Dynamics is now recruiting to this fantastic PhD opportunity in partnership with Sulzer.<br /> <br /> As a student on the CDT you will participate in a four-year programme that combines an integrated MSc (completed over the first two years) paired with a three-year PhD-level research programme. This gives you a combination of bespoke taught modules and inter-disciplinary research training.<br /> <br /> You will be part of a supportive cohort of research students with different academic backgrounds, all focusing on different aspects of Fluid Dynamics. During the taught aspects of your course you will receive a range of tailored seminars, lectures and practical laboratories to cover the computational, experimental and analytical aspects of Fluid Dynamics. This provides you with a strong background to the fundamentals of Fluid Dynamics. In addition you will have access to a wide range of personal development activities.

<p>Please visit the <strong><a href="https://fluid-dynamics.leeds.ac.uk/">EPSRC Centre for Doctoral Training in Future Fluid Dynamics</a></strong> website to find out more about the programme.</p> <p style="margin-right:-1px; margin-bottom:11px; margin-left:-1px"><strong>The PhD project: Multi-scale corrosion assessment of additively remanufactured metallic components used in flow equipment</strong></p> <p>Additive manufacturing is achieving rapid adoption in flow equipment, such as pumps, offering significant advantages over traditional manufacturing through new design freedoms, material-usage efficiencies, and bespoke production. However, corrosion remains a major challenge, causing rapid degradation of materials as a result of interaction with aqueous environments. ‘Additive remanufacturing’ is a specific additive manufacturing technique used to rework damaged or worn components, restoring their function with notable cost, lead-time and environmental benefits to industry. Despite the unique benefits of remanufacturing for flow machinery, there is a requirement to understand the aqueous corrosion behaviour of additively remanufactured components.</p> <p>This PhD will investigate the corrosion behaviour of additively remanufactured metallic flow components in collaboration with Sulzer. This interdisciplinary PhD project will develop the necessary corrosion understanding of remanufactured stainless steel in aqueous CO2-containing environments, typical of geothermal energy and carbon capture infrastructure. Corrosion behaviour of traditional manufactured materials has been widely studied, but understanding has yet to be established for additively remanufactured materials. Developing this understanding is essential, particularly in demanding aqueous flow environments that can lead to high rates of corrosion. Of particular interest in this project will be the interface between the original traditional manufactured component and the additively remanufactured repair zone, where galvanic and localised corrosion may be initiated. Using advanced electrochemical techniques, the localised corrosion mechanisms will be examined at the micro-milliscale within fluid droplets. This behaviour will then be evaluated using macroscale hydrodynamic experimental methods to evaluate the suitability of remanufactured metals for industry application.</p> <p><strong>Company spotlight</strong></p> <p>Sulzer Ltd is internationally renowned leader in flow equipment technologies; particularly high-performance pumps used in shipping, energy generation, and transportation of fluids. Sulzer has a large-scale manufacturing and testing facility in Leeds. This studentship will hugely benefit from the direct support and mentoring from the research and production staff at Sulzer, complemented by access to equipment and materials to facilitate the research.</p>

Applicants to research degree programmes should normally have at least a first class or an upper second class British Bachelors Honours degree (or equivalent) in an appropriate discipline. The criteria for entry for some research degrees may be higher, for example, several faculties, also require a Masters degree. Applicants are advised to check with the relevant School prior to making an application. Applicants who are uncertain about the requirements for a particular research degree are advised to contact the School or Graduate School prior to making an application.

The minimum English language entry requirement for research postgraduate research study is an IELTS of 6.0 overall with at least 5.5 in each component (reading, writing, listening and speaking) or equivalent. The test must be dated within two years of the start date of the course in order to be valid. Some schools and faculties have a higher requirement.
