A knowledgeable teacher, please help me figure out how to deal with this

I have a screw conveyor in my hands; upon opening it, I found that the spiral coating (it seems to be an electroplating process) had come off. I tested the material of this coating, and its composition is quite unusual. Moreover, this coating is only present on the outer edge of the spiral, covering an area of about 3 cm in width, while the rest of the surface is made of ordinary 316 stainless steel. So the question is: how should I repair this situation? Where can it be repaired? This thing comes from the Japanese devils, so sending it back to the factory for repair is too costly and unnecessary. Thank you first!
The coating shouldn’t be an alloy structure, right? This is a cobalt-based alloy; plating should not be used. Cobalt-based alloys are generally used in applications requiring high temperature and wear resistance; it is recommended to have them handled by professional maintenance personnel or manufacturers.
Yes, I also don’t think it’s plating, but I don’t know exactly how to do it! !
Come on, it won’t affect your use, so just make do with it:lol:lol:lol
Look for professionals who specialize in this; if possible, it’s also okay to choose those based in China
Isn’t this a Stellite cobalt-based alloy? It’s welded, right, and then machined
This is the screw inside the centrifuge, right? The layer on top is there to improve wear resistance. In China, it’s common to coat it with cemented carbide. It seems that the wear isn’t severe yet; if you need, I can coat it again for you
