“…13,17 In the present study, ZrB 2 -SiC composites were heated upto 800°C and eroded that resulted in the formation of zirconia (ZrO 2 ), boria (B 2 O 3 ), and silica (SiO 2 ) (as per the following Equations 1 and 2). 31,32 ZrO 2 and B 2 O 3 form as a result of oxidation of ZrB 2 , whereas SiO 2 forms as a result of oxidation of SiC.…”

“…Furthermore, as SiO 2 is more viscous and less volatile than B 2 O 3 , the oxidation resistance of ZrB 2 -SiC composites depends on SiC content. 13,17 In the present study, ZrB 2 -SiC composites were heated upto 800°C and eroded that resulted in the formation of zirconia (ZrO 2 ), boria (B 2 O 3 ), and silica (SiO 2 ) (as per the following Equations 1 and 2).…”

“…[1][2][3] However, poor oxidation resistance in high temperature conditions (in excess of 1200°C), poor hardness, fracture toughness and flexural strength restrict use of ZrB 2 ceramics for high temperature structural components. 11,12 Zhang et al 13 reported higher ablative resistance for ZrB 2 -15 vol.% SiC compared to ZrB 2 -30 vol.% SiC composite. 11,12 Zhang et al 13 reported higher ablative resistance for ZrB 2 -15 vol.% SiC compared to ZrB 2 -30 vol.% SiC composite.…”

“…4,5 The reinforcement of SiC into ZrB 2 improves hardness (17-26 GPa), [6][7][8] fracture toughness (3.5-5.5 MPa m 1/2 ), 7,9,10 and enhances the oxidation resistance as well as thermal shock resistance at higher temperature. 11,12 Zhang et al 13 In addition to high temperature oxidation and strength degradation, atmospheric particles are likely to impact on the surfaces of structural components of space vehicles. 15 In particular, the material undergoes inelastic deformation by the abrasive action of the atmospheric debris particles during the take-off, re-entry, or landing of space vehicles, and result into material loss.…”

This research work deals with the investigation of erosive wear of spark plasma sintered ZrB2‐SiC composites with variation in angle of incidence (30°, 60°, and 90°), test temperature (room and 800°C) and SiC content (10, 20, and 30 vol.%). Results indicate a large variation in erosion rate from 2.13 to 75.45 mm3/kg with change in angle of incidence, test temperature, and SiC content. Erosion rate decreased with the decrease in angle of incidence, increase in temperature, and increase in SiC content. With increase in SiC content from 10 to 30 vol.%, a maximum reduction of 68% in erosion rate obtained at shallow incidence and room temperature, and a maximum reduction of 78% in erosion rate obtained at shallow incidence and 800°C. SEM‐EDS and XRD analyses indicate that formation of B2O3 and SiO2‐rich protective surface is responsible for high temperature erosion resistance of ZrB2‐SiC composites.

“…ZrB 2 has a relatively low density compared with other UHTCs, which makes it a promising material for use in extreme environments, such as sharp leading edge and control surface components on hypersonic vehicles [2][3][4]. ZrB 2 -SiC composites are currently considered as the baseline ultra-high temperature ceramic composites owing to the fact that the introduction of SiC not only improves the mechanical properties of ZrB 2 by inhibiting the grain growth during sintering, but also increases the oxidation resistance of ZrB 2 by promoting the formation of silicate-based glasses that inhibit oxidation at temperatures between 800 and 1700 ℃ [5]. However, the inherent brittleness and poor thermal shock resistance of ZrB 2 -SiC ceramics are still obstacles for their engineering applications [6].…”

ZrB 2 -SiC-C f composites containing 20-50 vol% short carbon fibers were hot pressed at low sintering temperature (1450 ℃) using nanosized ZrB 2 powders, in which the fiber degradation was effectively inhibited. The strain-to-failure values of such composites increased with increasing fiber content, and the value for the composite with 50 vol% C f was even more than 3 times higher than that of the composite with 20 vol% C f . Furthermore, the composite exhibited non-brittle fracture mode when the fiber content was above 30 vol%, and the thermal shock critical temperature difference of the composite with 30 vol% C f was up to 727 ℃, revealing excellent thermal shock resistance of this composite. Additionally, ZrB 2 -SiC-C f composites displayed good oxidation resistance when the fiber content was below 40 vol%, suggesting that this method provides a promising way for preparation of high-performance ZrB 2 -SiC-C f composites at low temperature.

This study investigates the mechanical properties and erosion resistance of high temperature–pressure carbon‐epoxy novolac insulation reinforced with ZrB2/SiC particles. For this reason, at first, five samples were fabricated using the hot press, which included resin epoxy novolac EPN1180 base without reinforcement and four samples containing resin with 20:80, 30:70, 40:60, and 50:50 of SiC: ZrB2 particles respectively. After manufacturing of the samples, the mechanical properties were evaluated through bending and tensile testing, followed by erosion resistance properties by the use of oxyacetylene flame erosion tests. Chemical composition and surface morphology analysis of the composites were conducted using energy‐dispersive spectroscopy, scanning electron microscopy, and x‐ray diffraction analysis. Results indicate that the addition of ceramic particles enhances both mechanical properties and erosion resistance of the composite. The pure resin sample exhibited the highest weight loss and thickness reduction, while the sample containing 40% SiC and 60% ZrB2 demonstrated the least weight loss and thickness reduction about 55% and 83% respectively compared to pure sample. Additionally, the sample with 30% SiC and 70% ZrB2 had the lowest backside temperature. Furthermore, the sample with 20% SiC and 80% ZrB2 exhibited the highest mechanical properties, with a tensile strength of 422.5 MPa and flexural strength of 587.11 MPa. Morphological analysis revealed the presence of phases such as SiO2, ZrO2, and ZrSiO4 attributable to the ZrB2/SiC particles, contributing to the enhancement of erosion resistance.Highlights Examines volume ratios of ZrB2/SiC. Discovers the best particle ratio (20%SiC, 80%ZrB2) for mechanical properties. Identifies the best particle ratio (30% SiC, 70% ZrB2) for erosion resistance. Reveals key phases enhancing erosion resistance with advanced analysis methods. Linear and mass ablation rate improved by 83% and 55% (best formation).
