Experimental Investigation on Metal Coating by Means of ESD

摘要

The technology of electro-spark deposition has been investigated and the thickness of H13 steel coating up to 16.2μm has been achieved by applied SH-1000 electro-spark deposition power. It analyzed the effect of parameters such as voltage, discharge frequency, argon gas flow and rate deposition on the deposition thickness. The optimum deposition parameters have been selected through the orthogonal design. In order to improve coating quality, a novel method based on ultrasonic-assisted electro-spark deposition has been put forward.
