Influence of polarization curve slope on the accuracy of local copper electrodeposition from sulphate electrolyte

Local electrochemical deposition is an emerging technique, used in the field of additive manufacturing. The advantage manufacturing lies utilization room temperature electrolyte and permits to manufacture microscale objects with high precision. increase current increases area, so measures are be taken focus electric field. This work describes influence polarization curve slope on accuracy local deposition, both experimentally by computer modelling. copper was deposited using rotating anode surface stainless steel from sulphate electrolyte. composition investigated. profile parts analyzed profilometry microscopy. increased amount sulfuric acid presence shown changing cathodic 320 1100 mA V–1cm–2).
