Abstract：Particles reinforced nickel-based alloy composite cladding layer is increasingly applied in engineering which could significantly improve the surface properties of machine element. In this paper the main reinforced particles of the nickel-based alloy composite cladding layer were summarized. The overview of the properties of hard ceramic particles, rare earth and self-lubricating particles were given, as well as the microstructure and properties of the nickel-based alloy composite cladding layer reinforced by them. The key problem and development direction were pointed out as well.
Key words：particles reinforced；Ni-based alloy；composite cladding layer；wear resistance；rare earth
