| 中文摘要 | 用等离子喷涂方法在45号钢基体表面制备了锆钛酸铅(PZT)陶瓷涂层,并用扫描电镜(SEM)、X射线衍射仪(XRD)、透射电镜(TEM)、纳米压痕测量仪和d33准静态测量仪等检测手段对涂层的微观形貌、成分、纳米硬度、弹性模量和压电常数等各项性能进行分析,并测量涂层的介电温谱。结果表明:等离子喷涂制备的PZT陶瓷涂层具有典型的层状结构,结构致密,孔隙率为1.96%;纳米硬度和弹性模量平均值分别为5.881GPa和113.413GPa;压电常数达到了74pC/N,并且由介电常数与温度关系图可推知PZT的居里温度约为370℃。制备的PZT涂层性能良好,使其在实际工况中的使用成为可能。; PZT piezoelectric ceramic coatings were prepared by plasma spraying on 45 steel substrate,then the microstructure morphology,phase composition and mechanical properties of the coatings were analyzed by scanning electron microscope(SEM),X-ray diffraction(XRD),transmission electron microscope(TEM),nano-indentation tester and Belincourt-type quasi-static d33 meter.The results show that PZT ceramic coatings by plasma spraying preparation have a typical lamellar structure,dense structure and low porosity;the surface of the PZT coatings were smooth,and characteristics of porosity is 1.96%.The average nana-hardness and modulus of elasticity were 5.881 GPa and 113.413 GPa,respectively.The piezoelectric constant reaches 74pC/N.Through dielectric constant and temperature diagram,the Curie temperature of PZT can be inferred to be about 370℃.The performance of the PZT coatings is good,so that the good effect can be acquired in actually working condition. |
