Hi, everyboday. I am facing a problem about the anti-corrosion of stator:
We use silicon steel and punch it to the shape we need. And then we will weld them together to form a stator about OD200mmx180mm Length.
Because there are many deep grooves on ID, we tried several coatings to protect the stator: Zn coating and black oxidation; but the results of both are bad. There are corrosion on ID and grooves. The reason is 1. For Zn coating, it could not be plated on the groove,2. For black oxidation, because we need to remove the oil before assembly, so it is corroded quickly in application.
We considered to paryline coating, but at present there seems no factory who can work on such large part.
We are wondering if someone can help us with this? We want to find a way or coating to protect the stator. Thank you in advance.
