“…The material of the contrate gear is 20Cr2Ni4A, which is an excellent carburized steel, and high hardenability, after carburizing and low temperature tempering, the surface hardness is very high, and the heart strength and toughness and plastic fit are very good [12]. And the gap between the contrate gear teeth is very small, which is difficult to process by conventional mechanical cutting methods.…”

In the field of aviation, the contrate gear is an important component, the material of the contrate gear is the basis for ensuring the reliability and high performance of the aircraft engine, the commonly used material for contrate gear is 20Cr2Ni4A. In order to fully understand the electrolytic machining of the toothed groove of the contrate gear, a multiphysics coupling model of the electric field, the gas-liquid two-phase flow field and the temperature field was established to study the distribution of bubble rate, temperature, conductivity and current density in the processing gap. Simulation results show that the temperature and bubble rate gradually increase along the process direction in the processing gap, the conductivity and current density of the electrolyte gradually decrease.
