Solid particle erosion-wear behavior of SiC–Si 3 N 4 composite ceramic at elevated temperature

Tribological Behavior of Silicon Carbide Ceramics - A Review

“…The erosion rate reduced by one order of magnitude at 850 o C (0.10 mg/g) compared to that at 25 o C (2.20 mg/g). At 850 o C, the difference between erosion rates at 90 o and 30 o (0.02 mg/g) was much less than that found at 25 o C (1 mg/g), which attributed to increased ductility of composite at 850 o C. Similarly in a recent study, 63) solid particle erosion rate of SiC-Si 3 N 4 composite at elevated temperature increased firstly up to 800 o C, and then decreased with increase in temperature to 1400 o C. At lower temperature (up to 800 o C), wear occurred by brittle fracture where stripping of aggregates of composite resulted in loss of protection from the matrix. On the other hand, plastic deformation and oxidation protection dominated at higher temperature (beyond 800 o C).…”

“…Wang and Levy 64) reported that erosion for SiC fiber reinforced SiC composite at 25 o C occurred by cracking and chipping of the matrix as well as the fibers, while erosion rates considerably decreased at 850 o C owing to the increased ductility. Li et al 63) studied the erosion mechanism for SiC-Si 3 N 4 composites at different temperatures (25 o C-1400 o C). At low temperature, material removal occurred mainly by brittle fracture and stripping of aggregates as the protection from the matrix was lost.…”

“…Erosion rate ranges from 10 −1 to 10 3 mm 3 /kg based on erosion parameters, and microstructural and mechanical characteristics of SiC ceramics. [61][62][63][64][65][66][67] The complex tribological behavior of SiC ceramics and their composites in sliding and solid particle erosion conditions was mostly explained by several material removal mechanisms such as mechanical fracture, chipping, plastic deformation, ploughing, and/or formation and removal of tribooxide layer. [39][40][41][42][43][44][45][46][47][48]68) Considering the importance of the influence of microstruc-S Review ture and mechanical properties of SiC ceramics in different wear conditions, a comprehensive understanding on sliding and solid particle erosion wear behavior of SiC ceramics and composites is provided in the present review.…”

The investigation of the effect of particle size and velocity on solid particle wear properties of basalt base glass-ceramics

“…In the tests performed at 60°, scrapping effect activated, possibly. In ceramic materials, this trend is common result, generally [11,12]. In low impact angles, erodent particles hit to surface and rebound, hence, strong impact effect can't occur.…”

Low‐Temperature Synthesis of Graphene/SiC Nanocomposite Anodes with Super‐Long Cycling Stability

“…SiC has many attractive propertiessuch as broad band gap, high critical breakdown electric field, high thermal conductivity, excellent mechanical properties and good chemical stability, etc ,,. It has been widely used as high‐temperature structural materials, new generation of power semiconductor devices and wear‐resistant materials and high frequency, high power and radio resistance materials, and so on ,…”
