Surface Finish

March 1, 2011

Hi,
How are you ?

My question is how to work to Asst chamber ?
What type of corossion comes in ASST analysis, Green, white or Red ?
We are using in filter aid Cello salt (Atotech chemistry) but Cello salt not properly work because suspended particles are not removed in plating bath.
Grade of Cello salt?

Note: I am working with Faucet industry and base mat. Brass. So, please suggest because huge rejection rate due to microroughness, pitting and pinhole.

Hi, Amit.

You should ask Atotech or another supplier to come in and look around. The roughness could be from anodes, inadequate filtration turnover rate, etc. How many turnovers per hour are your filters working at? Unfortunately, I am not understanding all of your words.

Regards,

Ted Mooney, P.E.
