ฉันรัIf you remember, you sent samples were some were heat treated, some hand polished and passivated and some only electro polished. These (and many others parts and vendors) were used in salt spray tests which is almost finished. Result were very a little spread between the parts and to summarize the testing result we would need some further info regarding the passivation.
For the parts that are passivated… Could you describe what kind of passivation was used and the steps involved. E.g. do you have any documents regarding the process. What acid is used, how long time, if it varies from part to part etc.
Please get back to me with this info as soon as you can. We are looking to summarize all test and come to an conclusion what requirements we have after we are done.
