development of nano zro2 reinforced self flowing low
Tribological behaviour of nano-zirconia reinforced iron
For obtaining low friction and improved wear properties various techniques have already been developed including reinforcing of bearing materials with solid lubricants. Recently several self-lubricating composites have been used for the design and development of plain bearings . These self-lubricating composites are reinforced with hard materials for the enhancement of their hardness
