Enhancement in wear resistance of sintered silicon carbide at various temperatures

Wear mechanisms of silicon carbide subjected to ultrasonic nanocrystalline surface modification technique

“…2. It has been reported earlier in our previous studies that the UNSM technique was able to increase the hardness and Young's modulus of SiC at the top surface [15,16], which may be attributed to the reduction in large interconnected pores and modified top surface layer with a thickness of about 4 mm as shown in Fig. 3.…”

“…Moreover, it is worth mentioning here that the UNSM technique has a significant effect on the mechanical, structural, and tribological properties of SiC sliding against bearing steel and alumina (Al 2 O 3 ) ceramic at various temperatures under dry and oillubricated conditions, respectively. [15,16]. However, in spite of excellent results, there is still a lack of knowledge about the effectiveness of UNSM technique on the tribological properties and wear mechanisms of SiC ceramic under water-lubricated conditions.…”

Preparation of Siliconized Graphite by Liquid Silicon Infiltration of Porous Carbon Materials

“…Siliconized graphite combines the merits of graphite material with self-lubrication, excellent electric conductivity, thermal conductivity, thermal shock resistance, high-temperature strength, and the advantages of silicon carbide with high hardness, oxidation resistance, and corrosion resistance. Therefore, siliconized graphite has been widely used in machinery, chemical industry, metallurgy, aviation, nuclear industry [1][2][3][4], such as bearing material and mechanical sealing material [5][6][7].…”
