Scientists from the International Advanced Research Centre for Powder Metallurgy & New Materials (ARCI) developed a process for size-selective deposition of nanocomposite coatings, which can reduce the friction of these dynamic systems.

The aerospace, defence, automobile, space devices are in need to reduce friction, wear, and tear caused in the device in order to enhance the life of components. At present, to reduce friction, the dynamic systems are lubricated, which adds to the cost, complexity, and weight of these systems.

Nanocomposite coatings:
♦ The newly developed coating is of nickel tungsten-based with impregnation of particular sized Silicon Carbide (SiC) submicron particles. It uses economical and straightforward pulsed electroplating or electrodeposition process.
♦ It can provide an excellent combination of wear and corrosion resistance with the low friction coefficient and good oil retention capacity.
♦ The coating can withstand corrosion due to salt spray better than many similar wear-resistant coatings available in the market.
