    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.

    Abstract: A system may include a substrate having a tensile strength of at least 10,000 PSI at an ambient temperature. The system may also include a carbon rich layer deposited on the substrate, wherein the carbon rich layer comprises at least one of a carbide, a nitride, a boride, a silicide, an oxide, a sulfide, or a transition-metal or non-metal ceramic-forming element, wherein the carbon rich layer comprises a carbon content including sp2 carbon and sp3 carbon, wherein the carbon content has greater than 40% sp3 carbon, a sp2/sp3 ratio of the carbon content is less than 1.5, or both. The carbon-rich layer is designed to reduce or prevent the formation of adherent scales on flow system surfaces used in well production, fluid injection or gas sequestration, and includes electrically-actuated downhole components having dynamic sliding surfaces.
