Funded EngD Scholarship: Addition of Alloying Agents to Improve the Performance of Zn/Al Metallic Coated Steel

Swansea University - Engineering

Start date: October 2018

Sponsoring Company: Tata Steel Colors

Tata Steel Europe (TSE) is the second largest producer of pre-painted steel in Europe. To maintain this position, the organisation is constantly trying to improve the current product range, either through the development of best in class coatings for the construction industry, improved offerings in service or through added functionality. The majority of the premium coated products produced by Tata Steel Colors combine Zn/Al metallic coated steel substrate with advanced Cr(VI) free organic coatings, which allows Tata to offer the warranties of up to 40 years.

The aim of this project is to add different alloying additives to the Zn/Al coating to further improve corrosion performance or maintain performance at lower coating thickness.

Project Aims: 

  • Introduce new alloying additives e.g. Mg, to Zn/Al coatings and assess their impact on corrosion resistance using analytical techniques such as SVET and time lapse imagery.
  • Determine how additions to the Zn/Al metallic coating would affect the paintability, corrosion performance and durability of organically coated products.
  • Understand the relationship between modified Zn/Al coating thickness with corrosion performance in comparison with conventional systems.

Candidates should hold an Engineering or Physical Sciences degree with a minimum classification level of 2:1 or equivalent relevant experience. This project is suitable for a materials or chemistry student, with an interest in sustainability or paint chemistry.
