“…In contrast to solutes, reinforcing particles typically involve the incorporation of highmelting-point and hard materials. For instance, Wu's group [184,188] introduced SiC and TiC particles into L-DEDed Al 2 O 3 -ZrO 2 ceramics. These hard particles did not undergo melting during laser heating and disperse uniformly in the as-printed components, as shown in figure 13(i).…”

Ceramic oxides, renowned for their exceptional combination of mechanical, thermal, and chemical properties, are indispensable in numerous crucial applications across diverse engineering fields. However, conventional manufacturing methods frequently grapple with limitations, such as challenges in shaping intricate geometries, extended processing durations, elevated porosity, and substantial shrinkage deformations. Direct additive manufacturing (dAM) technology stands out as a state-of-the-art solution for ceramic oxides production. It facilitates the one-step fabrication of high-performance, intricately designed components characterized by dense structures. Importantly, dAM eliminates the necessity for post-heat treatments, streamlining the manufacturing process and enhancing overall efficiency. This study undertakes a comprehensive review of recent developments in dAM for ceramic oxides, with a specific emphasis on the laser powder bed fusion and laser directed energy deposition techniques. A thorough investigation is conducted into the shaping quality, microstructure, and properties of diverse ceramic oxides produced through dAM. Critical examination is given to key aspects including feedstock preparation, laser–material coupling, formation and control of defects, in-situ monitoring and simulation. This paper concludes by outlining future trends and potential breakthrough directions, taking into account current gaps in this rapidly evolving field.

“…Additionally, the presence of SiC particles can reduce crack energy by increasing the crack path length. SiC particles can also pin cracks, and prohibit crack development [46]. At last, the fracture toughness increases and the wear behaviour of the ternary composite coatings enhances.…”

This paper aims to study the effect of adding different SiC content on the wear performance of Al 2 O 3 -TiB 2 -SiC ternary composite coatings produced by the air plasma spraying process. The study used SHS powders as primary materials, consisting of H 3 BO 3 , Al, and TiO 2 , and 5, 10, and 15 Vol.% SiC. The microstructure and wear specifications of the coatings were characterised using FESEM, microhardness, and pin-on-disk methods. The results showed that the addition of SiC led to higher hardness and lower wear track width and rate compared to Al 2 O 3 -TiB 2 composite coatings. The best wear behaviour was observed in Al 2 O 3 -TiB 2 -10%SiC and 15 wt% SiC composite coatings. The main wear mechanisms were found to be brittle fracture, delamination and adhesive for all samples.

“…Although Ti 3 SiC 2 has to be seen as a potential structure/functional material as its combined metallic-and ceramic-like properties, the relatively low strength and hardness limit its further application. Al 2 O 3 ceramics with superb performances such as low price, high hardness, good corrosion resistance and stability at elevated temperatures [16], has been incorporated into Ti 3 SiC 2 to improve the mechanical properties.…”

Ti3SiC2/Al2O3 and Ti3SiC2-TiC/Al2O3 composite ceramics with various Al2O3 fractions were prepared by Ti, Si, Al, TiC and Al2O3 powers via in-situ reaction. Al2O3 contents in raw materials could influence the reaction process of Ti3SiC2 generated. It would lead to react completely when the Al2O3 volume percentage between 50% to 70%, otherwise TiC as an impurity would be found. Finally the Ti3SiC2/Al2O3 composites with 54.4 wt% Ti3SiC2, and Ti3SiC2-TiC/Al2O3 composites with 54.7 wt% Ti3SiC2 and 9.2 wt% TiC were fabricated successfully. There were two types of TiC existed in composites, called intragranular and intergranular particles. The Ti3SiC2-TiC/Al2O3 composite ceramics with 9.2 wt% TiC showed the higher mechanical properties than Ti3SiC2/Al2O3 composite. From the analyzing of microcrack propagation paths, the dispersed TiC particles as reinforcement agents would cause significant crack deflection, improving the flexural strength and fracture toughness up to 492 MPa and 7.8 MPa.m1/2 respectively.
