1results about How to "Improve cladding efficiency" patented technology

This invention discloses an ultrasonic vibration-assisted full-domain transient cladding device and method in the field of surface strengthening technology for components. The cladding chamber is equipped with an inert gas cylinder, an ultrasonic generator, and a vacuum pump on its exterior. Inside the cladding chamber, from top to bottom, are arranged an ultrasonic vibrating head, a perforated graphite felt, coating powder, a workpiece, and a third telescopic motor. The top surface of the workpiece is covered with a layer of coating powder. The perforated graphite felt has through-holes, and an ultrasonic vibrating head extends into one of the holes in the perforated graphite felt. Using air as a carrier, ultrasonic vibration is transmitted to the cladding layer. The workpiece itself does not vibrate, allowing the metal dendrites in the cladding layer to fracture during metal crystallization, promoting the growth of new crystal nuclei and achieving grain refinement. After the cladding layer is formed, the DC power supply is turned off, but the ultrasonic vibrating head continues to operate. The cladding layer of the workpiece impacts the ultrasonic vibrating head, forging the cladding layer and further improving its plasticity and mechanical properties.
