Influence of Cu on microstructure and wear resistance of TiC/TiB/TiN reinforced composite coating fabricated by laser cladding

Effect of high dilution on the in situ synthesis of Ni–Zr/Zr–Si(B, C) reinforced composite coating on zirconium alloy substrate by laser cladding

“…For those substrates, in order to obtain in-situ synthesized reinforcements, some adscititious particles (e.g., WC, TiC and Al 2 O 3 ) were needed to make decomposition before in-situ synthesizing in the molten pool. However, due to the violent and complex reactions in molten pool in short time, it is difficult to control the microstructure evolution using mixed powders or adding reinforced particles during laser cladding [18][19][20][21][22][23]. Yue et al [24] could not be ignored when cladding Ni-Cr-B-Si coatings on the surface of zirconium alloys.…”

Influence of Y2O3-SiC-Mo and Ce-Al-Ni amorphous alloy on laser melting deposition stellite matrix composites

“…2c). In fact, due to the dilution effect, lots of Ti entered into the molten pool from the substrate, favoring to formations of the TiB one-dimensional nanoscale precipitates [17].…”

Physical properties and microstructures of Fe3Al matrix laser amorphous–nanocrystals reinforced coating

“…Moreover, the diffraction ring image indicated that the TiB 2 nanocrystals were produced in coating. TiB 2 nano-particles applied in such coating can improve wear resistance, corrosion resistance and high temperature properties, and the nano-particles located on the grain boundaries could block the motion of dislocation, and also refined the microstructure of the coating [7][8][9]. And the amorphous ring and incomplete diffraction spots in polycrystalline ring revealed that a portion of the amorphous phases just began to crystallize when the laser molten pool had completed the solidification process.…”
