环文蛤角质层与棱柱层结合特性研究

Binding Characteristics of Cuticle and Prism Layer of Cyclina sinensis

采用JSM-6700F型扫描电子显微镜和CSM instruments Revetest Xpress Plus型划痕测试仪分别观察了环文蛤角质层与棱柱层表面微观形貌和测定环文蛤角质层与棱柱层之间结合特性。结果表明,当环文蛤角质层背面球形颗粒的粒径与棱柱层表面凹孔的孔径处在同一范围时,角质层和棱柱层的结合特性较好。环文蛤不同部位角质层表面形成的划痕存在一定差异,横向刻划时环文蛤各部分的摩擦因数变化波动比较大,纵向刻划时其摩擦因数变化波动均较小,角质层与棱柱层的结合情况相对较好,尤其是环文蛤腹部的角质层与棱柱层的结合情况更优。

In order to study the binding characteristics of cuticle and prism layer of Cyclina sinensis and apply it to improve the anti-corrosion performance of agricultural machinery,type-JSM-6700F scanning electron microscope and the revetest scratch tester of CSM instruments Revetest Xpress Plus were used to observe the surface microstructure and binding characteristics of cuticle and prism layer of Cyclina sinensis,respectively.The results showed that the binding characteristics of cuticle and prism layer was better when the spherical particles size of the back of Cyclina sinensis cuticle layer and the bore diameter of the prism layer surface were in the same range.The scratches of different parts of Cyclina sinensis cuticle surface existed a certain difference.The fluctuations of friction coefficient were large when horizontal scored and they were small when longitudinal scored.The results indicated that the binding characteristics of cuticle and prism layer was relatively better,especially the binding characteristics of cuticle and prism layer of Cyclina sinensis abdomen.
