利用化学气相渗透法(CVI)在束丝SiC纤维表面沉积BN和BN/SiC两种界面层,并将其制备成mini碳化硅复合材料。应用扫描电镜(SEM)观察了界面层和mini复材的表面和断口形貌,应用原子力显微镜(AFM)表征了界面层的表面粗糙度。采用X射线衍射(XRD)和透射电镜(TEM)对界面层结构进行表征,利用电子万能试验机对mini复材的拉伸性能进行分析。结果表明,CVI方法制备的BN表面光滑,为层状-岛状生长,与基体结合较弱,其mini复材拉伸强度为970MPa。热处理后的BN结晶度增强,表面粗糙度增大,与基体的结合略微增强,其mini复材拉伸强度有所提升,为1050 MPa。BN/SiC界面层表面粗糙,为岛状生长,与基体的结合较强,其mini拉伸强度最高,为1720MPa。 |

BN and BN/SiC interphases were prepared on the surface of SiC tows by chemical vapor infiltration(CVI).The tows were furthered deposited a thick SiC layer to form mini SiC composites,whose tensile properties were tested.The surface and cross-section of interphase and mini-composites were observed by SEM.The surface roughness of the interphase was evaluated by AFM.The crystal structure of interphase was characterized by XRD and TEM.The results show that the BN interphase prepared by the CVI method follows Stranski-Krastanov growth mode,possessing smooth surface and weak bonds with the matrix.After heat treatment,the crystallinity and the surface roughness of BN interphase increase,and the bond with the matrix is also slightly enhanced.The BN/SiC interphase follows V-W growth mode,possessing rough surface and weak bonds with the matrix.The tensile strength of mini-composites with BN,HBN and BN/SiC interphases are 970,1050 MPa,and 1720MPa,respectively. |
