Hard chrome coatings have gained wide acceptance as durable and high performance coatings on structural as well as engineering parts for wear and corrosion resistance. The hard chrome process utilizes chromium in hexavalent state in the plating bath and Cr6+ is a known carcinogen that evolves in the form of fumes during the plating process. As a result, enormous interest exists in finding suitable replacement for hard chrome coatings. Electrodeposited Ni-W-SiC alloy nanocomposite coatings have the potential to be a promising alternative for hard chrome replacement due to their hardness, high temperature thermal stability and process economy.
The present study will focus on the development of Ni-W-SiC alloy nano composite coatings by employing a novel pulsed electrodeposition technique from citrate bath. The structural, mechanical, tribological and corrosion properties of Ni-W-SiC coatings will be presented and compared with hard chrome and commercial NIKASIL coatings.
