Engineering: M2A Fully Funded EngD Scholarship: Wettability and bonding of coating alloys on substrates

Closing date: 28 February 2018

Key Information

Start Date: October 2018

Sponsoring Company: Tata Steel

The manufacturing of coated light weight alloys for transportation is critical for meeting the required standards for emission. Technical challenges involve coatability and adhesion on complex substrates with highly engineered micro-structures and requirements for the coated materials to survive processes such as hot-pressing and joining.  New coating alloys (Zn-Mg, Zn-Mg-Al, etc.) are being developed for galvanic protection of steel sheets for such automotive applications. The steel sheet substrates themselves are becoming more complex in micro-structure, ranging from simple IF steels to DP steels to TRIP and TWIP steels to future (Fe-Al-Mn-C-Ni) Low Density Steels for light weighting. As the steels become more complex in chemistry, so does the surface micro-structure in terms of selective oxides, phases, etc.  in order to engineer coating procedures, it would be beneficial to develop a laboratory scale test which allows for coating drops to be dropped onto pre-characterized steel substrates for controlled lengths of time under carefully controlled atmospheres and temperatures.  The purpose would be to (i) image the wetting behaviour of the melt, (ii) allow it to solidify and react with the substrate under controlled conditions for post characterization through SEM-EDS and TEM.

Project Aims:

  • Construct a laboratory setup of for the aforementioned purpose. It would include a high speed imaging system and a small scale sessile drop furnace ideally heated through IR with controlled atmosphere in terms of Ar/O2/H2.
  • Carry out experiments for a simple model system, e.g. Zn on Fe or IF Steel under various oxidizing conditions.
  • Carry out experiments for a selected AHSS, wherein selective surface oxidation and other surface heterogeneities are expected. Coatings will be gradually increased in complexity from Zn, to Zn-Mg to Zn-Mg-Al.

The samples (substrate and coating) will be selected such that they are of relevance to TATA Steel UK’s product lines.
