“…After adding appropriate rare earth, the microstructure of the coating was lath martensite and retained austenite, the micro-hardness and corrosion resistance were all enhanced. Li et al [13] coated the Fe 3 Al+SiC−TiB 2 −Al 2 O 3 +CeO 2 mixed powder on the Ti-6Al-4V alloy. The composite coating and the substrate had a good metallurgical bonding.…”

The TiC/Fe-based composite coating with different CeO 2 content was fabricated on the Cr12MoV steel by laser cladding. The microstructure of cladding layers all had the planar grain, columnar grain, cellular grain, and equiaxed grain. Without adding rare earth, TiC ceramic particles had the irregular shape, large size difference, and a certain degree of reunion. Appropriate rare earth could effectively spheroidise and refine ceramic particles, and made the distribution uniform. Excessive rare earth could cause the burning loss of ceramic particles, inhibit the formation of second precipitated phases, and the reunion of particles occurred again. The Ti element, decomposed from TiC ceramic particles, combined with the Fe and Cr elements to form the Ti/Fe/Cr or Fe/Ti/Cr compounds. Hence, the metallurgical bonding between particles and cladding layer metal was increased. The micro-hardness and wear properties of the cladding layer had a close relation with the shape, size, distribution, and the form of TiC ceramic particles.

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.
