Phase constituents and microstructure of laser cladding Al2O3/Ti3Al reinforced ceramic layer on titanium alloy

Surface modification of titanium alloy with the Ti3Al + TiB2/TiN composite coatings

“…[18] Thus, during the cladding process, a large amount of TiB 2 was melted completely in the molten pool of sample 2 because of low TiB 2 content, and then precipitated in a highly dispersed way during its crystallization. [19,20] It is noted that the microstructure of the laser-cladded coating in sample 3 was finer than that of the coating in sample 2 because of its higher TiB 2 content (Figs 1(a) and (b)). As shown in Fig.…”

Effect of SiC/nano‐CeO2 on wear resistance and microstructures of Ti3Al/γ‐Ni matrix laser‐cladded composite coating on Ti–6Al–4V alloy

“…Furthermore, during the cladding process, the chemical reaction between a portion of Al 2 O 3 and TiB 2 took place as follows: …”

Preparation, microstructural evolution and properties of Ni–Zr intermetallic/Zr–Si ceramic reinforced composite coatings on zirconium alloy by laser cladding

“…The laser cladding is one of the most promising surface technologies because of metallurgical bonding between coating and substrate, lower content of oxides and porosity, as well as high efficiency [21][22][23]. Current researches mainly focus on laser cladded coating on steel [24][25][26] and light metals (such as aluminum [27][28][29], magnesium [30][31][32][33], titanium [21,[34][35][36]). Riveiro et al [25] cladded aluminium on AISI 304 stainless steel by high power diode laser and reported that the width and height of coating were both mainly dominated by the cladding speed while the depth of coating was mainly controlled by the mass flow and scanning speed.…”
