“…In the study of Sun et al [35], the glass forming abilities of AleNieCe, AleNieLa and AleNieY were investigated and the AleNieY system showed a higher glass forming ability. Besides, the AleNieY amorphous phases have been reported in the cladding coatings [36]. Though Al, Ni, and Y all existed in the molten pool, AleNieY amorphous phase was not spotted out in this paper, which might be attributed to the limited amount of Al and Y.…”

“…However, the energy distribution of the laser beam was uneven. Thus, a portion of the nano-Y 2 O 3 particles in the edge of facula were able to retain the nano-metric size, which diffused into every location of the molten pool due to their high diffusion coefficient [11]. As is shown in Fig.…”

Laser cladding of the Al3Ti+TiC+(Ni-coated WC) pre-placed powders on titanium alloy can form the Ti3Al/Al3Ti matrix composite coating, which improves the surface performance of the substrate. With addition of nano-Y2O3, this composite coating exhibited a finer microstructure. In this study, the Al3Ti+TiC+(Ni-coated WC)+nano-Y2O3 laser-cladded coatings have been researched by means of X-ray diffraction and scanning electron microscope. The function of nano-Y2O3 acted as the heterogeneous nuclei, and the growth of the grains was hindered by Y2O3 and Y. Y2O3 can also decrease the temperature of the molten pool. Thus, the probability that grains traverse potential barrier decreased, leads to more stability of the grains.K e y w o r d s : coatings, rare earth compounds, laser cladding, intermetallics, diffusion

In this study, the Al/Mg powders were firstly used to improve the wear resistance of titanium by mean of the laser cladding technique, which owned a great potential in the field of the surface modifications of the metals. Laser cladding of the Mg/Al+TiN pre-placed powders on pure Ti can form the TiN reinforced composite coatings. With addition of 10wt.%TiC, the growth of the TiN was retarded in a certain extent, which further increased the wear resistance of the coating. This research provided essential experimental and theoretical basis to promote the application of the laser cladding technique in the manufacturing and repairing of the aerospace parts.
