Selecting Passivation Technique(s) for Corrosion-Resistant Alloys to Complete Fabrication


Organizer: Nickel Institute
Venue: Online Platform –Zoom
Speaker: Dr Graham Sussex
Date: 26 Jul 2024
Time: 06:30pm - 08:30pm
Registration Close Date: 24 Jul 2024


Join us for an insightful webinar on selecting the most effective passivation techniques for Corrosion-Resistant Alloys (CRA) to ensure successful fabrication. This event will address common contamination issues in welded fabrications, such as grease, carbon steel contamination, and heat tint. Attendees will learn about various treatment sequences to restore the passive surface, including solvent or caustic washing, surface abrasion, chemical pickling, and chemical or electrochemical passivation. Additionally, the session will cover the limitations and applications of the more recent scanning laser ablation technique.

6:30 pm – 6:40 pm: Welcome and Introduction
6:40 pm – 8:00 pm:
