quality of Anodiz....

[IAMaxxer]

Can you judge the quality of anodizing by the lenght of time it takes to strip it off?
WE reanodize RC car parts, and the factory anodizing color comes off quicker and easier than when we have restripped our work.
Can I assume that ours is a better job than factory?

I have noticed alot of parts from Dye paintball seems to strip amazingly quick except for clear parts, But im not sure why

I would say yes... the ease at which a part strips is an indication of the durability of the ano.
Just my opinion, though... could be other factors I'm not considering.

[destroyer125]

parts ran in larger part runs seem to be less durable, also parts people do on their own and stripped down are usually done in a short amount of time, where as Ano's from a factory sit for 6-8 months probably before the part is stripped by you and is drained of the excess light oils and such used to restore oil to the surface, like WD-40

Just more guess'es

*** NOTE *** In my experience I have found that a clean, degreased part will strip more rapidly, effeciently and evenly oppsed to one that is oily or dirty.

I would think that the anodic layer's pore size and thickness would determine the duration of the stripping process (not including bath parameters of course...Temp, concentration, agitation, ect...). Having said that, a thicker layer will obviously take longer to completely strip away in comparison to that of a thinner layer. I would have to assume that a larger pore would decrease the length of time required to strip the film as the larger pore would allow for more chemical to funnel inside and therefore stripping at a more aggressive rate.

Conclusion? It would seem that a part which takes longer to strip would have a thicker, denser anodic layer. Is this how you might judge the quality of an anodized layer? I suppose...If the layer is thick with small pores and yet absorbed the dye effectively - I would think that it is a wonderfull anodic layer.

This is of course, just my hypothesis...And my $0.02.
