Hi Dedi

Yes possible to use metal spray to repair the bearing housing. I assume you would subcontract this out to a job shop?

Most likely they would use Arc Spray with a NiAl bond coat, and a 13% Chrome Steel 420 SS top layer. The thickness should be no problem at all.

Do you have your own equipment? Do you need a job shop recommendation?
