surface roughness and cleaness
surface roughness and cleaness
(OP)
I want to understand the downsides of the amplitude on the surface being too rough and the relationship between surface roughness and the degree of cleanness (Sa2, Sa2.5,... SA3).
From what I know, the peaks of metal will be exposed through the primary coat, but what if we thikens the primary a little bit to manage that. Because from what I have seen before it's hard to obtain a degree of cleeness of SA 2.5 for exemple in the roughness range required (40 to 75 um).
Thank you in advance.
