Would a thermal spray coating have a marked difference in adhesion for wrought vs cast C276? The characteristics of the two components are definitely different…

We had a cast nozzle tip coating delaminate and the zirconia coating held up well on the wrought section. Granted there are markedly different atmospheres operating there but I wasn’t sure if this was a common thing
