    摘要:

    采用箔-纖維-箔 (FFF) 法分別制備無涂層、C涂層和Cu/Mo雙涂層改性的SiCf/Ti6Al4V復(fù)合材料，對制備態(tài)復(fù)合材料的力學(xué)性能和界面微觀組織進(jìn)行對比分析，進(jìn)一步研究不同真空熱暴露處理對Cu/Mo雙涂層改性復(fù)合材料的界面微區(qū)的影響規(guī)律。結(jié)果表明，制備態(tài)下Cu/Mo涂層比C涂層較好地改善了復(fù)合材料的界面組織和性能，且對基體和纖維中元素擴(kuò)散均具有一定的阻擋作用；求得900 ℃下SiCf/Cu/Mo/Ti6Al4V界面反應(yīng)的生長動力學(xué)公式為H=1.380t1/2+ 5.397

    Abstract:

    Foil-Fiber-Foil (FFF) method was used to prepare Ti6Al4V-matrix composites reinforced by SiC fibers without coating, with C coating and Cu/Mo duplex coatings, respectively. The mechanical properties as well as interfacial microstructure of the as-prepared composites were compared. Moreover, the interfacial reaction characteristics of the SiCf/Cu/Mo/Ti6Al4V composites were also investigated by different vacuum heat treatments. The results show that for as-prepared samples, Cu/Mo coating is better than C-coating to improve the interfacial microstructure and properties of titanium matrix composites; the growth kinetic expression of the SiCf/Cu/Mo/Ti6Al4V interfacial reaction at 900 ℃ is H=1.380t1/2+5.397
