| Abstract: | The basic principle of the plasma spraying technology for piezoelectric material is that the precursor ceramic powder injected into plasma jet is heated,accelerated and projected on to the subtrate. The droplets are deformed and solidified at the surface of substrate and the coating is formed. It is easy to develop piezoelec tric sensors and actuators from plasma piezoelec tric coating by polarization in certain conditions.The piezoelectric elements based on this technol ogy have the characteristics of high productivity,small size with thin coating and can be utilized without bondage. Some problems such as high porosity, contamination and volatilization, poor cohesion may be overcome by optimizing the processing parameters. |
