Corrosion Resistance of Super Duplex Stainless Steels

Key Information

Super duplex stainless steels (SDSS) offer an appealing combination of properties, providing superior levels of strength and corrosion resistance than more heavily-alloyed (and expensive) alternatives. Three main SDSS alloy types were developed through the 1970’s by Sandvik (S32750), Weir Materials (S32760) and Langley Alloys (S32550) with slightly varied compositions - the main differences being additions of Cu and W to influence pitting corrosion resistance.

  The influence of both Cu and W additions has been previously studied, with sometimes conflicting results by different groups, although the choice of electrolyte/environmental conditions can affect results.

Project Aims

The successful candidate will work as part of the leading corrosion group at Swansea University. The project will utilise advanced techniques such as SVET and time-lapse microscopy as well as more conventional electrochemical methods to;

1) Gain greater insight into the passivation phenomenon from Cu (and W) additions in SDSS

2) Identify conditions under which chosen alloy(s) provide enhanced performance

3) Seek to identify optimum alloy additions based upon insight gained of passivation phenomenon

Suitable candidate 

The role will be suitable for someone with a background in;

·       Materials Science and Engineering

·       Chemistry

·       Physics

·       Or equivalent industrial experience
