Investigation of Dependency of Microstructure Quality on Vibration Mode

摘要

The quality of microstructure, created on polycarbonate (PC), by using hot imprint process and changing vibration parameters is investigated in this paper, in order to reveal the best option and further successfully apply this process in research and industry. Earlier it was revealed, that high frequency excitation, with usage of vibroactive pad, made from aluminum and piezoceramic (PZT-4) positively affects the quality of microstructure. Now, when working regimes are known it is necessary to find out which of them influences the quality of created microstructure best. Thus the experiment, when holding all parameters of the process constant, and only changing vibration modes, which are already known, is carried out. After the experiment qualitative analysis, using optical microscope is performed.
