Dr Julian Wharton is a Associate Professor within Engineering and the Environment at the University of Southampton.

Current position

Julian Wharton is a lecturer in corrosion and surface engineering at the University of Southampton, UK; Deputy Director of the National Centre for Advanced Tribology at Southampton (nCATS); and Programme Coordinator for Mechanical Engineering with responsibility for overseeing the undergraduate and master’s degree courses in the Faculty of Engineering and the Environment.

Career history

Julian Wharton graduated in 1993 with a BSc(Hons) in Applied Chemistry from Portsmouth University . He obtained a PhD at the Loughborough University in 1997 for research into non-chromate conversion coatings sponsored by the DRA at Farnborough. He joined Engineering Materials at the University of Southampton in 1997 as a postdoctoral researcher, investigating methods to sense and study localised corrosion processes.

Research interests

Tribocorrosion:  Wear resistant materials functioning in corrosive environments and subject to abrasive wear often fail prematurely due to the combined effects of coupling wear (mechanical process) and corrosion (electrochemical process). Wear-corrosion interactions can lead to either an increase or a decrease in the overall mass loss.

There are a number of projects which either have  been or are currently under investigation:

  • Tungsten-carbide based sintered hardmetals and sprayed coatings for downhole drilling operations.
  • Metal-on-metal hip replacement CoCrMo alloys.

Biocorrosion:  Microbial activity may induce or enhance corrosion reactions.  The deterioration of a metal, either directly or indirectly, as a result of bacterial activity is often called as microbiologically influenced corrosion (MIC).  MIC is also known as biological corrosion, biologically induced corrosion and biocorrosion.

Green Tribology

Tribology is the study of friction, lubrication and wear. Decreasing friction by any means always leads to welcome reductions in fuel and energy consumption, with a corresponding decrease in carbon dioxide (CO2) emissions.
