| 英文摘要 | Ni3al-hbn-ag intermetallic matrix composite coating was prepared on ni-based superalloy by reactive sintering. the crystalline phase and microstructure of the coating were examined by means of x-ray diffraction (xrd), scanning electron microscopy (sem), and energy dispersive spectroscopy (eds). the results showed that the hbn particles pretreated by electroless nickel plating and hot-dip aluminizing and ag particles with a size of several micrometers were homogeneously dispersed in the nial matrix, and the composite coating had strong interfacial bonding with a fine and dense microstructure. during the reactive sintering, an exothermic reaction between ni and al associated with a transient liquid phase occurred, leading to in situ synthesis of the densified ni3al matrix in the coating with a high tensile strength of more than 70 mpa. the high-temperature tribological properties evaluated on a ball-on-disc test rig showed that the coating possessed self-lubricating properties from room temperature to 800 degrees c due to a synergetic lubricating action of ag and hbn.
