Effect of Electrothermal Alloy Composition on Ceramiccoreatomization Performance
To investigate the influence of electrothermal alloy components on the performance of ceramic cores,a series of ceramic heating atomi-zers were prepared using a thick film firing process.This process employed conductive pastes with varying ratios of nickel,chromium,and iron el-ements.The heating temperature,atomization lifespan,and total particulate matter(TPM)of these atomizers were then examined.The influence mechanism of electrode composition and surface morphology on atomizer performance was assessed by scanning electron microscopy(SEM),en-ergy dispersive spectrometer(EDS),high-speed temperature collector and electronic cigarette smoking machine.The results showed that:1)Increasing the nickel and chromium content,and reducing the iron content in the electrode under the same power output condition of the atomi-zer,will enhance the heating temperature and fatigue life of the atomizer,and can also reduce the TPM fluctuation caused by the increase in smoking instances.2)Changes in the content of nickel,chromium,and iron elements in printed sintered alloy electrodes have little effect on the change in electrode resistivity,while the thickness of the electrode print has a more significant impact on resistance.3)Preparing a dense molten metal state on the surface of the alloy electrode can improve the heat transfer efficiency of the electrode and increase the surface temperature of the electrode,resulting in higher atomization efficiency.
