Preparation and Salt Spray Corrosion Resistance of Ni/BN and NiCrAl/BN Coatings

摘要：

　　Ni/BN and NiCrAl/BN abradable sealing coatings used in turbo engines were prepared by plasma spray technology.The phases and the microstructures of the coatings were characterized with X-ray diffraction (XRD) and scanning electron microscopy (SEM).Corrosion behaviors of these coatings were investigated with open-circuit potential (OCP) and salt spray corrosion test.The results showed that the NiCrAl/BN possess better corrosion resistance as compared with Ni/BN.
