The Effect of Pulse Energy on the Defects and Microstructure of Electro-Spark-Deposited Inconel 718
Abstract
Electro-spark deposition (ESD) is a technique whereby material is deposited from the ESD applicator towards a substrate via an electro-spark phenomenon. One potential use for this technique is to repair minor damages on turbine blades made of Ni-based superalloys, such as IN718. To better understand the effect of the processing parameters on the quality of the deposition, in terms of defect formation and the microstructure during the ESD …
