Research history

• Topographical Characterization (since 1997) Generation of 3-D surface topography data using the non-causal 2-D auto-regressive model for tribology and surface metrology

• 3-D Parameters for tribology

• Contact simulations

• Water Lubrication and Tribo-Corrosion (since 2002) Tribological research for the development of metal-based water hydraulics using stainless steel, brass and DLC

• Mechanisms of the droplet impingement erosion in nuclear power plants focusing on mechanical-chemical interaction (National Research Project)

• Modeling and simulation of tribo-corrosion (This is what I am going to study during my stay in Southampton)

Miscellaneous

• Development of the portable friction tester (PAT. P JAPAN)

• Tool wear monitoring using a laser displacement sensor and AE

Skills * Programming for the experimental apparatus, analysis software and numerical simulations (mainly with Visual C# and C++)

• Experiments on tribology with the electro-chemical setups

• Operating instruments such as a profilometer, SEM, EPMA, AFM and nano-indenter Visit Details Sponsorship: the Japan Society for the Promotion of Science Host Researcher: Prof. Robert. J. K. Wood

Subject of Research: Research on electrochemistry and potential-drop under corrosive wear environment

• Aim Friction and wear in aqueous solutions are affected by the synergy between the mechanical and chemical factors. The surface open-circuit potential drops when the fresh surface is exposed. How much? The rate of contributions of the factors? A numerical analysis is needed to understand the phenomena.
