UA Startup Caltrode Tackles Galvanic Corrosion

March 2, 2016
Posted in:
Researchers have invented a new type of sensor designed to work effectively in high-temperature environments, and it has implications for solar power, nuclear reactors and petroleum refining.

The metal alloys used in pipes corrode faster when the temperature of the material that flows through them is higher.

University of Arizona College of Engineering professor Dominic Gervasio and principal research specialist Hassan Elsentriecy from the Department of Chemical and Environmental Engineering, in collaboration with Peiwen "Perry" Li from the Department of Aerospace and Mechanical Engineering, have invented a new breed of sensor — a reference electrode — designed to work in these ultrahigh-temperature environments.
