摘要:Amorphous surrounded nano polycrystals (ASNP) are found in this study. An amorphous nanocrystal-reinforced coating was fabricated on an important aeronautical material Ti-6Al-4V titanium alloy by laser cladding of the Al3Ti-TiB2-SiC-Cu-Y2O3 mixed powders. Transmission electron microscope and scanning electron microscope test results indicated that with Cu addition, the TiCu2Al nano polycrystals were produced in the matrix of laser clad coating, which grew along (200), (220), (222), and (400) planes; high resolution transmission electron microscope image indicated that with glass addition, the particles grew up, leading to the formation of a micronano structure. Moreover, Cu addition led the agglomeration of ASNP to decompose then distributed uniformly in the coating matrix. This research provided essential theoretical and experimental basis to promote the application of laser cladding technique in the modern aviation industry.
