Hi Steph

Can plasma sprayed coatings be applied to coated substrates? Yes in some cases where coating has high integrity and will accept surface preparation like grit blasting without damage.

Can CoCrAlY APS coating stick on top of Aluminum-Silicon coating? Not sure, I suspect so, but really it is something you will have try out and test for yourself.

Can be removed physically using waterjet however depends on job that can sustain the stresses during the physical removal process

Does anyone knows if plasma can be used to coat fine graphite powder on copper plate. This is to be used as electrode.

Thanks
