beta phase
HVOF CoNiCrAlY

Dear Gordon,

In this attaced photo, I did not EDX but assuming that the bright diffused layer between coating (hvof CoNiCrAlY) and base (Ni base alloy) and the fine bright phase in coating was Beta phase? Please advise.

Hi Mehongbo

Sorry, little experience with CoNiCrAlY microstructures, (I assume after heat treatment), so can't comment on beta phase. Hopefully, we may have other members that can, so probably best to address your post to everyone rather than just me (I don't know everything, in fact I know very little Happy0193).

RE: beta phase
No sorry. At least you provide a place to ask. We will see if there is any input from other experts then.
Thanks again Gordon.
