| 摘 要： | 采用等离子喷涂技术在碳／碳复合材料上制备了羟基磷灰石（HA）涂层，用扫描电镜（SEM）观察了涂层的微观结构．用X射线衍射仪（XRD）分析了涂层的相组成，并测定了涂层与基体的结合强度。结果表明：在碳／碳基体表面获得了具有一定粗糙度的羟基磷灰石涂层；在等离子喷涂过程中，发生了羟基磷灰石的非晶化现象，经过热处理后可转变为晶相；涂层与基体的剪切强度为7.15MPa。 |

| Abstract: | A simple plasma spraying method was employed in coating hydr oxyapaptite (HA) on to carbon/carbon composites(C/C composites). The morphology of the coating was examined under scanning electron microscope (SEM). The phase con stitutions of the HA coating were determined by X-ray diffractometer (XRD). The shear strength of the HA coating-C/C composite substrates was detected. A hydro x yapatite coating with rough surface was observed. A considerable amount of amorp hous phase appeared as a result from the coating process, which could be tran sformed into the morphous phase crystalline HA after subsequent heat treatment. The shear strength between the H A coating and C/C composite substrates was 7.15 MPa. |
