Innovative high performance coatings for grain oriented electrical steel

Key Information

Supervisors: Dr Pleydell-Pearce, Dr J Searle and Dr F Robinson

Expected Interview Date: week commencing 17th June 2019.

Cogent Power Ltd is a producer of World Class electrical steels including grain-oriented products at Orb Works in Newport. 

Grain oriented electrical steel is an essential material in the manufacture of energy-efficient transformers and large high-performance generators. 

The unrivalled magnetic properties result from the unique grain structure, formed through a complex production process, starting with high-silicon hot-rolled coil feedstock. 

The coatings applied to grain-oriented steels play a critical role in their performance providing insulation between laminations, holding the steel strip in tension to reduce magnetic losses and reducing magnetostriction during magnetisation and demagnetisation of the transformer core in service. 

There are two coating layers present on grain oriented electrical steel, namely Forsterite and tension coating. The Forsterite layer can exhibit variation in coverage, colour and thickness that is accentuated by the current tension coating, which is undesirable and solutions are sought to minimise or eliminate. 

This research aims to improve consistency of appearance, colour and adhesion combined with increasing the tension applied and avoidance of sticky coatings. 

The Research Engineer will: 

  • Develop a practical and academic understanding of the grain orientated electrical steel tension coating process and product. 
  • Applied knowledge gained on the surfaces and coatings to explain current deviations in tension coating performance and to work collaborative with Orb personnel in problem solving activities to optimise the current system. 
  • Identify / consider potential for improving surface cleanliness, surface treatment / conditioning prior to coating and tension coating to deliver an innovative next generation tension coating system. 
  • Conduct laboratory scale research on the surface cleanliness, surface treatment / conditioning / surface reactivity and coating options identified by feasibility studies.
