Can plasma be applied to coated substrates?
Can CoCrAlY APS coating stick on top of Aluminum-Silicon coating that was slurry, pack or gas phased applied or will this have a negative effect on bonding???

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

Hi hanker886

Though this post deserves a thread of its own, go to [split] Can plasma coat graphite on copper?
