Beschreibung
Zusammenfassung:	A method of manufacturing a surgical instrument that includes an energized feature operable to apply ultrasonic energy or RF energy to tissue. The method includes forming at least one of a microscopic surface pattern or a nanoscopic surface roughness into a base surface of the energized feature to produce at least one recessed portion. The method also includes applying a hydrophobic coating that includes at least one of silicone, titanium nitride, chromium nitride, or titanium aluminum nitride to at least the recessed portion of the energized feature after forming at least one of the microscopic surface pattern or the nanoscopic surface roughness.
