Muto-Nishimoto Lab
Machine-translated · View original
The lab uses electrochemistry to uncover how metals corrode and to create materials that do not rust.
AboutAbout the lab
Understanding how corrosion occurs, at the atomic and electronic level.
Muto-Nishimoto Lab investigates electrochemical reactions on metal surfaces at the molecular, atomic, and electronic levels.
The aim is to create corrosion-resistant alloys and technologies that prevent corrosion.
Because the surfaces of real materials are not uniform, the lab uses micro- and nanoscale electrochemical measurements, chemical imaging, and scanning probe microscopy.
By observing metals dissolving in situ, the lab analyzes reactivity at the nanoscale and develops technologies to control it.
Key terms
- Electrochemical reaction
- A reaction that involves the transfer of electrons. Metal corrosion and battery discharge are both examples
- Pitting corrosion
- Corrosion in which a very small area of a metal surface dissolves deeply, forming a hole
- Passive state
- A state in which a very thin oxide film forms on a metal surface, making it resistant to further dissolution

ResearchResearch themes
The lab studies electrochemical reactions on metal surfaces at the molecular, atomic, and electronic levels, with the goal of advancing surface functions and improving corrosion resistance. In addition to developing corrosion-resistant alloys and corrosion protection technologies, it develops techniques for evaluating and analyzing corrosion resistance, sensors for that purpose, and new surface modification technologies.
*Illustrative imageCorrosion-resistant materials for a circular, resource-recycling society
Building on the electrochemical measurement and in situ observation techniques developed in the lab, it is developing new, highly corrosion-resistant structural materials suited to a resource-recycling society.
*Illustrative imageImproving the pitting corrosion resistance of stainless steel
In passive metals such as stainless steel, nonmetallic inclusions in the steel become the starting points of pitting corrosion. This research aims to improve pitting corrosion resistance by controlling the electrochemical properties of the inclusions.
*Illustrative imageMaking light metals more corrosion-resistant through surface treatment
Using new surface treatments such as plasma in liquid, the lab works to give light metals, including aluminum, magnesium, and titanium alloys, ultra-high corrosion resistance.
*Illustrative imageAlloys for additive manufacturing in harsh environments
For use in harsh environments, the lab develops alloys for additive manufacturing (metal 3D printing) that have excellent environmental resistance.
