Overview

Electrochemical analysis reveals corrosion behavior of alloys in molten solar salt, suggesting longer lifespan for FeCrAl.

Key Points

  • This research aims to understand the in situ corrosion behavior of alloys in molten solar salt to improve thermal energy storage systems.
  • Used electrochemical impedance spectroscopy for in situ analysis of corrosion behavior.
  • Conducted post-exposure characterization with scanning electron microscopy and energy-dispersive X-ray spectroscopy.
  • Evaluated corrosion of stainless steel SS316 and Kanthal FeCrAl alloys in molten solar salt at elevated temperatures.
  • FeCrAl alloys showed superior corrosion resistance due to protective oxide scale formation.
  • SS316 may enhance corrosion resistance over longer exposure times.
  • Findings highlight the potential for improved materials in thermal energy storage applications.
