“…Therefore, it is confirmed that the tribo‐chemical oxidation is the dominant wear mechanism for ST30 at 900°C. It is because of the oxidation of material and the formation of oxide film that such outstanding antiwear property can be achieved …”

Si 3 N 4 as a structural ceramic is desirable for applications in spacecraft, transportation, and energy, but its poor high-temperature properties still do not satisfy the actual requirements. Here, a TiC 0.3 N 0.7 reinforced Si 3 N 4 ceramic is successfully designed and fabricated via the high-temperature nitridation of TiC x . It is found that TiC 0.3 N 0.7 grains with the size of 1-2 μm are uniformly dispersed in the Si 3 N 4 matrix and show a firm bond with substrate. Compared with pure Si 3 N 4 , the doping of harder TiCN phase can effectively improve ceramic's hardness and fracture toughness at a certain temperature. Importantly, the ceramic material displays extraordinary wear resistance across a wide temperature range (eg, the wear rate of TiC 0.3 N 0.7 containing Si 3 N 4 over 63 times and 178 times better than pure Si 3 N 4 at 600 and 900°C, respectively). More broadly, a correlation between wear mechanism and temperature is established, and the result shows that the mechanical strength and tribochemical oxidation as two key factors determine the wear behavior of the material. These results developed here can provide a springboard for preparation and optimization of multiphase ceramics that serve under hightemperature conditions.

“…Table S2 shows the parameters of the wear test. The wear volume ( V ) of the wear track on the flat specimens is defined in Figure S1b, and the value of V can be calculated from the formula where W , d , and L are the width, depth, and length of the track, respectively, and r is the curvature radius of the cross section. After the tests, the wear surfaces of the tested specimens were investigated by the NANO FEI-450 SEM to analyze the wear mechanism.…”

Here, a unique combination of a novel carbon-nitrogen source (g-CN) with different mole ratios of Ti/g-CN has been utilized to fabricate iron matrix composite coatings by a synchronized powder feeding plasma transferred arc (PTA) cladding technology. The results show that submicron Ti(C,N) particles are successfully fabricated in situ on a Q235 low carbon steel substrate to reinforce the iron matrix composite coatings and exhibit dense microstructures and good metallurgical bonding between the coating and the substrate. The microstructure of the coating consists of an α-Fe matrix and Ti(C,N) particles when the mole ratio of Ti/g-CN is no more than 5:1. The microhardness and wear resistance of the coating gradually improve with increasing abundance of the in-situ-synthesized Ti(C,N) particles. Interestingly, for a Ti/g-CN mole ratio of 6:1, a fine lamellar eutectic Laves phase (FeTi) appears, and this phase further improves the microhardness and wear resistance of the coating. The microhardness of the coating is 3.5 times greater than that of the Q235 substrate, and the wear resistance is enhanced 7.66 times over that of the substrate. The Ti(C,N)/FeTi and FeTi/α-Fe interfaces are very clean, and the crystallographic orientation relationships between the phases are analyzed by high-resolution transmission electron microscopy (HRTEM) and an edge-to-edge matching model. The theoretical predictions and the experimental results are in good agreement. Furthermore, based on the present study, for the solidification process near equilibrium, smaller interatomic spacing misfits and interplanar spacing d-value mismatches contribute to the formation of crystallographic orientation relationships between phases during the PTA cladding process. The existence of orientation relationships is beneficial for improving the properties of the coatings. This work not only expands the application fields of g-CN but also provides a new idea for the preparation of Ti(C,N) particle-reinforced composite coatings.

“…The method of preparation of AMCs has a crucial role to attain a clear interface and homogeneous distribution of ceramic particles. The literature reveals that very little work has been done on the microstructural features and wear behaviour of the Al 2014-based composites reinforced with TiB 2 particles produced by casting, melt stirring, powder metallurgy and in-situ production methods [15][16][17][18][19][20]. However, limited literature appears to exist reporting on the effect of TiB 2 particles on the microstructural, mechanical and wear properties of Al 2014-based composites produced by vacuum infiltration.…”

In this study, microstructural, mechanical and wear properties of TiB 2 reinforced Al 2014-based composites produced by vacuum infiltration were investigated under different production temperatures. It was observed that the microstructures of the composites consisted of Al matrix and TiB 2 particles. TiB 2 particles exhibit various shapes such as cubic, triangle and spherical. It was observed that the hardness and porosity of the composites increased with increasing TiB 2 content. It was also observed that the production temperature has an important effect on the porosity and hardness of the produced composites. The highest wear resistance was obtained from Al 2014-8% TiB 2 composite among the materials tested. It was observed that the production temperature and hardness are effective parameters on wear of produced composites. Evaluation of microstructural and mechanical test results suggest that it would be beneficial to keep the production temperature around 800 °C and Al 2014-8% TiB 2 composite can be recommended for engineering applications where the hardness and wear resistance are considered to be significant factors.
