The result is a soft, controllable plume that follows a programmed path over the substrate without overspray bouncing off the surface, which is what makes the technique the workhorse for fuel-cell catalyst-coated membranes (CCMs), gas diffusion electrodes, perovskite and silicon photovoltaic interlayers, sensor films, and lab-scale battery electrode coupons.\u003c\/p\u003e\n\n\u003cp\u003eCompared with doctor-blade or slot-die coating, ultrasonic spray excels where the deposit must be thin (sub-micron to a few microns), where the substrate is fragile or non-flat (membranes, GDLs, frits, 3D parts), or where the ink is dilute and high-loss processes are unaffordable.

Unlike conventional air-pressure spray guns, which use high-velocity air to \"blast\" liquid into droplets, ultrasonic spray systems utilize piezoelectric vibrations to create a much more controlled and uniform spray.\u003c\/p\u003e\n\u003cdiv data-path-to-node=\"5\" style=\"text-align: start;\"\u003e\n\u003cp\u003eThe process starts with an ultrasonic nozzle, which contains piezoelectric transducers. (1) \u003cstrong\u003eVibration to Mist\u003c\/strong\u003e: When high-frequency electrical energy is applied, the transducers vibrate longitudinally. Liquid is introduced to the nozzle tip, where these vibrations create standing waves. When the amplitude reaches a certain threshold, the liquid \"disintegrates\" into millions of micron-sized droplets. (2) \u003cstrong\u003eLow-Velocity Plume\u003c\/strong\u003e: Because the droplets are created by vibration rather than high-pressure air, they emerge as a low-velocity mist. A very low-pressure carrier gas (usually Nitrogen or Air) is then used to shape the spray plume and direct it toward the substrate. (3) \u003cstrong\u003eDroplet Uniformity\u003c\/strong\u003e: The droplet size is determined primarily by the frequency of the nozzle (e.g., 20 kHz, 50 kHz, or 120 kHz). Higher frequencies produce smaller droplets, which are ideal for the thin, dense membranes required for YSZ or GDC electrolytes.\u003c\/p\u003e\n\u003cp\u003eThe working mechanism of an ultrasonic spray is shown below:\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0774\/6591\/1526\/files\/EFSRCUSC_02_160x160.png?v=1776615216\" style=\"float: none;\"\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003ctable width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd\u003e\n\u003cul\u003e\n\u003cli\u003eEFLSPUSC (EFL-SPUSC)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cem\u003ePower\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd\u003e\n\u003cul\u003e\n\u003cli\u003eAC220V±10%, single phase, 50\/60Hz, 2000 W\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cem\u003eSpray Coater Features \u0026amp; Parameters\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd\u003e\n\u003cul\u003e\n\u003cli\u003eSpray Head Frequency: 100 KHz with concentrated type.
