| Abstract: | In this paper, the properties of NiCrFe/Al/hBN composite powder and coating prepared by four different
binders were compared and analyzed. The results showed that the curing performance and thermal degradation
performance of A3 binder match well with the powder preparation process and spraying process of NiCrFe/Al/
hBN composite powder. The morphology and performance of the composite powder were excellent. The seal
coating thus prepared exhibited uniform structure and good corrosion resistance to salt bath, with the hardness and
bonding strength of 62 HR15Y and 7.99 MPa, respectively. |
