“…In general, phenolic resin is susceptible to form a glassy carbon during pyrolysis. Glassy carbon is highly inert and impermeable to gases [1][2][3][4]7]. In the present study, the fibers in the layers and the space between the layers are covered by this glassy carbon.…”

“…Before CVI treatment, the tubes were polished with diamond wheel and then heated at 700 1C for 3 h to remove the free carbon. The parameters used for CVI treatment can be found elsewhere [2,3]. The SiC tubular products are shown in Fig.…”

“…Hence, these are widely used in structural, nuclear and semiconductor applications. Their high stability with respect to neutron radiation, associated with sufficient thermal conductivity, gives scope for potential application in nuclear industries [3][4][5]. Recently, SiC has become a prime candidate material for high-temperature heat exchanger applications, primarily because of its excellent thermal stability and corrosion resistance in severe environment, and sufficient thermal conductivity.…”

“…Many researchers have already investigated the effect of particle size on the solid particle erosion of various materials [29][30][31][32][33][34]. Some researchers reported that the erosion rate increases with a rise in the particle size up to a limiting size, beyond which the erosion rate becomes independent of the particle size [29,31,32].…”

Polymethyl methacrylate (PMMA) is one of the most popular synthetic polymers in aircraft windshields as an alternative to glass, due to its lightweight, high transparency and impact-resistant characteristics. The erosion behavior of PMMA is critical when used as an alternative to glass in an aircraft windshield. This paper presents experimental data on the effects of particle size, velocity and impingement angle on the roughness of PMMA, using 3D optical profilometry after solid particle erosion tests. Particular attention is paid to determining the different morphologies of imprints and cracks with regard to particle size, impact velocity and impingement angle. It is further shown that the removed volume in overlapping impacts measured by 3D profilometry is captured well. It is demonstrated that maximum erosion rate occurred at a 30° impingement angle and correlates well with the ductile erosion behavior of PMMA. Detailed worn surface analysis was performed using 3D optical profilometer scanning to investigate effects of particle size, velocity and impingement angle on the roughness of PMMA.

“…However, while mechanical properties such as strength, hardness and thoughness have been extensively evaluated [17][18][19][20][21][22][23], in the case of wear only erosion has been studied [24,25], and no sliding wear studies exist in the literature to the best of our knowledge. With this in mind, we have studied sliding wear of bioSiC derived from wood precursors of different species at different applied loads, with the double intention of obtaining relevant data of friction coefficients and wear rates as well as to elucidate the effect of microstructure and, ultimately, wood precursor, on these properties.…”

Biomorphic SiC ceramics were fabricated from four different wood precursors and their Knoop hardness and sliding wear resistance when sliding against a Si3N4 ball in air were studied.Tribological experiments were performed using a pin on disk apparatus, under normal loads of 2 and 5 N, at a sliding speed of 100 mm/s. The effects of specimen porosity and microstructure on measured wear were evaluated. A commercial sintered silicon carbide ceramic was also tested for comparison. Small differences in friction coefficient comparable to monolithic SiC ceramics were obtained. Several concurrent wear mechanisms are taking place: microfracture, plastic deformation in the Si phase and oxidation of the Si and/or SiC phase. The presence of an oxide tribolayer was assessed using fluorescence microscopy. Wear rates were found to scale with SiC content and depend on residual porosity in the composite.
