This invention proposes a high-load gear forming grinding method based on the local phase transition strengthening effect of liquid gallium assisted by ultrasonic rapid cooling. When room-temperature liquid gallium is transported from a constant-temperature storage tank to an ultrasonic atomizing device, the liquid gallium metal is vibrated by ultrasonic waves into atomized particles, which are then propelled forward. Due to the rapid increase in kinetic energy and decrease in internal energy, the ejected liquid gallium atomized particles quickly condense, forming a solid-liquid transition state. The direction of movement of the ejected liquid gallium droplets is controlled by charging electrodes and deflection electrodes, focusing the precise ejection of liquid gallium droplets into the core grinding area. During the solid-liquid transition process of the liquid gallium particles, a large amount of heat energy is rapidly absorbed on the gear processing surface. After thermal melting, gallium atoms react with titanium atoms to form a metastable gallium titanate compound, achieving local phase transition strengthening of the high-dynamic-load gear. This method utilizes the local phase transition strengthening effect of the liquid gallium solid-liquid transition process to significantly enhance the metal strength and toughness of the high-dynamic-load gear, which is in line with the concept of green development.
