Is hard anodizing influenced by size factor of component?




2006

What will happen if we subject two different components of different sizes (for example, say one 2 Kg's and other 20 Kg's) with identical properties, which one will have the higher hardness

Coming to our real problem.
in the same manner we subjected our components the one with lower mass shows much higher hardness than the one with higher mass, does it mean that higher mass components need to maintain in the bath for longer times compared to relatively smaller ones, if so are there any guidelines to follow in resolving the above issue

I am not sure that I fully understand the question, but the surface properties of the two parts should be the same, including their hardness. It sounds like the hard-coating on the larger part is defective for some reason, perhaps you do not have enough rectifier capacity.
