摘要	316L-30W composites were successfully fabricated via spark plasma sintering at 1550 degrees C to evaluate their potential as the interlayer between W and 316L stainless steel in fusion reactors. The effect of holding time on the microstructure and its subsequent effects on the fracture morphology and wear properties of the composites were investigated. The results show that more W particles melted and reacted with 316L steel as the holding time increased from 1 to 5 min. The generation of voids was mainly caused by the differences in diffusivity and the coefficient of thermal expansion between W and 316L. The 316L-30W composite held for 3 min had a smaller and more stable friction coefficient, indicating that its interface was firmly bonded and homogeneous.
