PhD Studentship - Lubrication Challenges - Impact of Electrostatic Charges on Bearings

Mechanical Engineering

Location:  Highfield Campus
Closing Date:  Tuesday 31 August 2021
Reference:  1347121DA

Supervisory Team:    Monica Ratoi, Brian Mellor

 Project description

Project fully sponsored by a Leading Oil Company

The proposed research aims to offer a generation of efficient lubricants optimised for the emerging technologies so as to overcome their long-standing problem related to hydrogen embrittlement. The atomic size of hydrogen enables it to diffuse readily through the lattice of solid materials and cause catastrophic failure in high strength steels. Embrittlement by hydrogen has been identified as a major consequence of hydrogen uptake and represents an extra challenge for lubricated tribological parts such as bearings that are normally subjected to high stresses. This study will investigate the influence of bearing material composition or type on preventing premature failure for any given lubricant due to the ingress of hydrogen produced by electrical discharges at the tribological contact. By understanding the mechanism of this process and how it is influenced by several factors, an informed selection of lubricants will be made to deliver superior energy savings and enhanced fatigue life. 

 The research will involve novel methods for investigating rolling contact fatigue, hydrogen embrittlement and the role of bearing materials and lubricants by employing a wide range of state-of-art technology. 

This is a unique opportunity not only to carry out doctoral studies and publish your research in high impact factor journals but also become one of the world’s leading specialist in lubrication for emerging technologies i.e. wind turbines, hydrogen fuel cells, electric vehicles etc. You will undertake interdisciplinary research at the National Centre of Advanced Tribology at University of Southampton, UK under the supervision of international experts in the fields of tribology, lubricant chemistry, and materials technology.
