A liquid marble is a droplet of liquid coated with micro or nano-particles. A novel method of localized electrochemical deposition (LECD) using liquid marbles and the feasibility of application of this method in additive manufacturing/micro-repair is studied.Controllability of the transportation of liquid marbles to any desired location by pick and place technique has been demonstrated by depositing a 3 X 3 grid pattern with 1 mm period using an in-house built CNC set up. Electro deposition experiments performed at defective spots with liquid marbles confirm the feasibility of micro-repair using this novel technique.

Application of electrochemical methods for micro repair is being researched. A liquid marble is a liquid droplet coated with hydrophobic micro or nano powders. When the liquid used is a suitable electrolyte, it can be used for localized electrochemical deposition (LECD) which is in turn used for micro repair. Though the feasibility of this process is already established, the properties of the deposit with respect to the metal substrate has to be studied. Corrosion is an important property that can vary between two metals. An immersion corrosion test is performed on a substrates having micro spots made using LECD using 5% NaCl for 240 hours. The results are compared with specimens of the same dimension which underwent the same corrosion testing process. It was found that the micro deposits did not affect the corrosion rate significantly and therefore localized electro deposition using liquid marbles may be considered as a potential method for micro repair.
