Current Topic:
aluminum vs. steel in brake disc
what are the key values for failure?  how does anodizing change the numbers?  i'm not worried about fatigue life for now.

anodizing doesn't change any numbers, the way I see it it keeps the numbers the same.   Anodizing creates a controlled oxydation layer that prevents further oxydation of aluminum.

In WW2, America shipped a load of airplanes in the Pacific war theater, with planes sitting on deck and under deck. The aluminum was not anodized. Salt water corrosion made the planes located on top deck useless and they were thrown overboard, if my story is correct.


Anodizing is thus not adding anything to a material, it is preventing subtracting useful qualities from it.
