摘要
A functionally graded sintered body consisting of laminated SiO2/Mo layers was fabricated using spark plasma sintering. A high sintered-body density was achieved using fine powders of SiO2 (4.0m) and Mo (1.3m), which ensured no cracks were formed between layers. The highest joining stress (1.2 MPa) was found to occur at the interface between SiO2 layers with 0 and 8 vol% Mo, with the electrical resistance decreasing rapidly when the Mo content was increased to 13 and 22 vol%. This is attributed to the use of spark plasma sintering, suggesting further work is needed to fully optimize this process.
