We have developed nano structured coatings ( Ni-CeO2/ZrO2, Ni-Co-SiC, Cu-SiC, Sn-CeO2, etc.) by pulse electrodeposition route. We have also developed Cu based functionally gradient nano composite material by pulse electrodeposition for electrical contact application. These developed materials have been characterized for their microstructure and different properties such as, hardness, wear, corrosion, electrical resistivity, etc.
We have also produced Al2O3 reinforced aluminium alloy (Al-Zn, Al-Zn-Cu, Al-Mn, Al-Zn-Mn, and Al-Cu-Mn) matrix composites by three different routes, i.e., reactive sintering, reactive milling followed by thermal treatment, and combined mechanical and thermal treatment and evaluated microstructure, wear and corrosion property. Low expansion Cu and Al based composites have been also produced using negative filler expansion material Y2W3O12 by high energy ball milling followed by sintering. Beside microstructure, wear and corrosion property, thermal properties (thermal expansion coefficient and thermal conductivity) are also evaluated for such low expansion composites.
Composite materials with steel matrix and ceramic particle reinforcements provide a scope of producing relatively inexpensive wear resistant materials. We have synthesized TiC reinforced iron-based composites from a waste product of aluminium extraction plant through an energy-efficient, economical and simple process. The composite has shown excellent wear resistance property. Beside Fe-TiC, we have also developed wear resistant Fe-ZrC composite by aluminothermic reduction of zircon sand and blue dust in the presence of carbon.
We have also synthesized TiC and (Ti,W)C reinforced austenitic manganese steel matrix (Fe-12Mn, Fe-17Mn and Fe-17Mn-3Al) composites by conventional melting and casting route which have shown excellent wear resistance property.
Although steel matrix composites show excellent wear resistance property, they do not possess good toughness resulting in restricted applications. Improvement in properties of austenitic manganese steel has been achieved by thermo mechanical processing. Currently, effort is being made to design and develop steels with good wear resistance and mechanical properties for wider applications.
