Abstract
 Nanostructured catalytic powders (NCP) were used to produce the laser melting deposition (LMD) amorphous-nanocrystalline composite coatings on titanium alloy. With amorphous alloy addition, amorphous surrounded nanoscale polycrystals (ASNP) and amorphous surrounded one-dimensional nanocrystals (ASON) were produced. A composite coating was fabricated by LMD of the Stellite 6-TiB2 mixed powders on a TA15 alloy. Scanning Electron Microscope (SEM) test results indicated that with Y2O3-SiC-Mo addition, a LMD amorphous-nanocrystalline composite coating was obtained. Addition of the Ce-Al-Ni amorphous alloy led a micro-nano structure LMD coating to be produced. This research provided essential theoretical and experimental basis to promote the application of LMD technique in the modern aviation industry. Key words
