摘　　要：采用活化燃烧合成法制备MoS2 /MoSi2 原位复合材料 ,用X -射线衍射仪 (XRD)对燃烧合成产物进行物相分析。结果表明 ,产物中MoS2 的相对含量与设计含硫量、球磨时间等因素有关。产物中的MoS2 量并不是随着设计含硫量和球磨时间的增加而线性增加。产物中MoS2 量在设计比例 2 0 %MoS2 、球磨时间 4h以及 5MoS 2/MoSi 2 in situ composites are produced by combustion synthesis with mechanical activation and pre heating. The mineral composition of combustion synthesis products is checked by X ray diffraction The quantity of MoS 2 in MoSi 2 matrix is related with milling time and the quantity of S in reactant powders The content of MoS 2 in combustion synthesis products does not increase with increase of design sulfur content and milling time, and its maximum is obtained on the condition of 20% design sulfur content, 4h milling time, and 50℃ pre heating temperature MoS 2/MoSi 2 in situ composites can be produced by combustion synthesis
