Abstract
A composite piezoelectric coating (CPC) method includes entraining a powder in a first carrier gas stream; heating a second carrier gas stream to a predetermined temperature; combining the first carrier gas stream and second carrier gas stream into a combined carrier gas stream; ejecting the combined carrier gas stream at a target at a predetermined velocity, and consolidating the powder on the target by impact of the ejected combined carrier gas stream with the target.
