Thermal Properties of Sulphuric Acid Anodic Coatings

Click For Summary
A 25-micron sulphuric acid anodic coating begins to break down at temperatures around 135°C, leading to significant degradation in its electrical properties. The discussion highlights concerns regarding the thermal stability of anodic coatings under high temperatures. Participants emphasize the importance of understanding the thermal limits to ensure the integrity of the coatings in various applications. The effects of prolonged exposure to elevated temperatures on the coating's performance are also noted. Proper temperature management is crucial for maintaining the effectiveness of sulphuric acid anodic coatings.

Hi,

Can anyone tell me at what temperature a 25micron sulphuric acid anodic coating will start to breakdown. I have noticed that after exposure to 135°C the electrical properties of the coating have dropped drastically.

Regards
Dan

Thread 'Need to anneal 5052 aluminum'

I need to anneal 5052 aluminum for a home project. Google has given me mixed results on how to do this. Short version is that I'm doing some heavy forming on a piece of 5052-H32 and I'm running into issues with it work hardening. I've tried the Sharpie trick with a propane torch. But I'm not sure this is doing anything. I'm also seeing conflicting opinions whether to quench or air cool. So I'm looking for some expert opinions. (Oven heating is not an option due to size.) Thanks. edit: The...
