I have a question: does anyone know whether the aluminum surface treatment Allodine 1200 can give rise to outgassing when used in high vacuum conditions ? As I understand it, it is a chemical deposition of CrO3 on the Al surface.
Aluminum Allodine 1200 is a chemical treatment used to protect aluminum surfaces from corrosion. It is also known as chromate conversion coating or chromate conversion coating.
Outgassing is the release of gases or vapors from a material, usually due to increased temperature or vacuum conditions. This can be a concern in scientific experiments as it can affect the accuracy and cleanliness of the environment.
In high vacuum conditions, there is very little air or gas present, so any outgassing from materials can significantly affect the purity of the environment. This can be a problem for sensitive scientific equipment that requires a clean and controlled environment.
Yes, Aluminum Allodine 1200 does outgas in high vacuum. It is a chemical treatment and can release gases at elevated temperatures or under vacuum conditions.
Outgassing from Aluminum Allodine 1200 can be reduced by baking the material at high temperatures before use. This process drives out any trapped gases and reduces the potential for outgassing in a high vacuum environment.
