Color of WC-Co coating grinded
Hello,

Now I have a porblem:
After grinding the coating, we did cleaning +FPI+cleaning. And then there exists blue marks on the coating like water marks. Do you know what is it and how does it happen?

Thanks guys.

Usually recommended (and required !) to perform FPI before Thermal Spraying.
