Electrodeposited Coating:

  1. Development of corrosion resistant functionally gradient Alloys (Ni-Zn):
This coating on steel consists of an alloy of Zn and Ni. Zn is anodic to Iron, whereas Ni is cathodic. Hence, a Zn-Ni undercoat followed by Ni coating provide a combination of cathodic and anodic coating 
  1. Development of corrosion resistant composite coatings (Ni-ZrO2, Cu-SiC, Ni-CeO2, Ni-Co-SiC) with high wear resistance:  
This composite assembly is designed to perform both as corrosion resistant as well as wear resistant coating. Ni and Cu provide cathodic protection to steel and hard particles like SiC, CeO2, and ZrO2 when dispersed within the matrix provide excellent wear resistance. Pulse electrodeposition technique is employed to synthesis this composite coating.
Lead-free Solder:
  1. Development of Creep resistant Sn-Cu-Y2O3 composite solder :
This Sn-Cu eutectic composition is an environment friendly alternative to the conventional toxic Sn-Pb based solders. The distribution of hard Yttria particles within the matrix enhances the creep property.
  1. Development of Creep resistant Sn-Ag-CeO2 composite solder:
Copper is replaced by silver for better conductivity
Electrodes for Li-ion battery:
  1. Development of Sn-alloy based porous multiphase electrodes for Li-ion battery:
 
Sn-alloys form intermetallics with lithium having capacities at least thrice than that of the commercial graphite electrodes. However, they suffer from high volumetric strain. In order to minimize the strain a porous multiphase tin alloy is electrodeposited on copper foil. This porous framework minimizes the strain by providing space for the lithiated product to expand.
    The conventional copper foil is replaced with a foamy current collector. The foamy structure was fabricated by electrodeposition by exploiting hydrogen evolution as dynamic template. The foamy collector buffers the volumetric strain generated at the interface of the collector and the electrode (Sn-alloy). Thus, it prevents the detachment of the electrode.
