摘要

采用多孔Ti3SiC2骨架SHS与Sn-10 wt % Pb熔体自发渗透相结合的新方法制备了Ti3SiC2 - sn (Pb)金属陶瓷。研究了燃烧结束与熔体入渗之间的时间延迟对金属陶瓷的自发入渗、密度、微观结构和相组成的影响。结果表明，Ti3SiC2 - Sn(Pb)金属陶瓷的相组成与时效关系不显著，主要由Sn、Pb、TiC和Ti3SiC2组成。结果表明，合成的金属陶瓷抗压强度为117 MPa，是Sn-10 wt % Pb合金抗压强度(47 MPa)的近两倍。

Preparation of Ti3SiC2–Sn(Pb) Cermet by SHS of Ti3SiC2 Porous Skeleton with Subsequent Spontaneous Infiltration with Sn–Pb Melt

Ti₃SiC₂–Sn(Pb) cermet was produced by a new method combining SHS of porous Ti₃SiC₂ skeleton and spontaneous infiltration with Sn–10 wt % Pb melt. The effect of the time delay between the end of combustion and the start of infiltration with melt on spontaneous infiltration, density, microstructure, and phase composition of cermet was investigated. It was found that the phase composition of Ti₃SiC₂–Sn(Pb) cermet does not significantly depend on the time delay and consists mainly of Sn, Pb, TiC, and Ti₃SiC₂. It was shown that the compressive strength of the synthesized cermet is 117 MPa that is nearly twice as large as that of Sn–10 wt % Pb alloy (47 MPa).

期刊介绍： International Journal of Self-Propagating High-Temperature Synthesis is an international journal covering a wide range of topics concerned with self-propagating high-temperature synthesis (SHS), the process for the production of advanced materials based on solid-state combustion utilizing internally generated chemical energy. Subjects range from the fundamentals of SHS processes, chemistry and technology of SHS products and advanced materials to problems concerned with related fields, such as the kinetics and thermodynamics of high-temperature chemical reactions, combustion theory, macroscopic kinetics of nonisothermic processes, etc. The journal is intended to provide a wide-ranging exchange of research results and a better understanding of developmental and innovative trends in SHS science and applications.
