Webinar: SEM-EDS Insights into Inconel 625 Corrosion Speaker: Teemu Paunikallio 29th of January, 2026 This session provides a deep dive into the high-temperature corrosion resistance of Inconel 625, a nickel-based superalloy. Our researcher Teemu Paunikallio examines how oxide layers form and eventually fail under harsh conditions, such as those found in waste-to-energy boilers. Key findings highlight the presence of dual oxide layers, the vaporization of volatile chlorides, and the identification of specific niobium-rich precipitates within the metal matrix. Highlights 0:44 – Scope Change: Explanation of why the content was split into two parts; this session focuses exclusively on Inconel 625 corrosion results. 1:24 – Next Event: Announcement of the follow-up webinar on March 5th regarding the selection of EDS systems. Technical Presentation 1:59 – Core Presentation: Teemu Paunikallio begins the detailed study on SEM-EDS analysis of Inconel 625 corrosion mechanisms. Focus: Analyzing oxide scale morphology and chemical composition. Q&A and Expert Insights 24:37 – Blister Formation: Discussion on a "void" in the oxide layer. Teemu confirms it is a blister and notes that it forms between two distinct oxide layers rather than directly at the metal-oxide interface. 25:12 – Absence of Metal Chlorides: An inquiry into why nickel or chromium chlorides weren't detected. Teemu explains that these products likely vaporized (e.g., as HCl gas) due to high temperatures. 26:12 – Durability Expectations: Insights into how long Inconel 625 lasts compared to stainless steel. While the test showed stability for 6 hours, its industrial value lies in its superior resistance in waste boilers. 27:11 – Niobium-Rich Particles: A technical question regarding whether certain particles are the "Eta phase" (δ-). Teemu suggests further point analysis with EDS and Raman is needed for definitive identification. Closing & Contact Info 28:12 – Collaboration: Instructions on how to contact Top Analytica for research partnerships. 29:01 – Final Wrap-up: QR code for feedback and a reminder for the March 5th session.
