Development of Joining and Coating Technique for SiC and SiC/SiC Composites Utilizing Nite Processing

Current status and critical issues for development of SiC composites for fusion applications

“…Initial work demonstrated that PHMS systems with appropriate filler materials for joining SiC, particularly as a field repair technology, were viable. The NITE SiC/SiC matrix processing technique was also applied for SiC joining [61]. The 'NITE Joint' demonstrated tensile strengths in excess of 200 MPa, however, the joining process requires pressurization at high temperatures in a controlled environment.…”

Recent advances and issues in development of silicon carbide composites for fusion applications

“…Of many joining techniques [13][14][15][16][17][18][19][20][21][22][23], NITE-joining is very attractive, since it allows a robust structure with the same composition of the matrix of NITE-SiC/SiC composites [15]. A 200 mm-long NITE-tube joint was successfully manufactured ( Fig.…”

Assessment of Silicon Carbide Composites for Advanced Salt-Cooled Reactors

“…The TEP joining takes advantage of reduced melting temperature for particular silica-bearing oxide systems (such as yttria-alumina-silica) to develop SiC-based joint material through the solution and re-precipitation process. The NITE joint belongs to this category, in which the joint material is ideally identical with the matrix material for the NITE SiC/SiC [32]. The selective area CVD is obviously the method that produces most radiation resistant joint of SiC [33].…”
