Research summary
AI-generated

Karthikeyan Hariharan works on the corrosion, oxidation, and degradation behavior of metals and alloys, including nickel-based superalloys made by additive manufacturing and high-entropy alloys produced from recycled scrap. Much of the recent work combines electrochemical testing with new analytical techniques (such as respirometry) to better understand how metals dissolve or oxidize in service, with an eye toward designing more corrosion-resistant structural alloys. Earlier work also touched on concrete and construction materials, though recent output is concentrated on metallurgy and corrosion science.
