    Abstract: The present disclosure discloses an oscillating-pressure-and-spark-plasma combined sintering equipment and sintering method. By providing a system comprising a mainframe structural system, a servo motor hydraulic system, an oscillating pressurized hydraulic system, a vacuum and inert gas supply system, a pulse plasma power control system, and a mainframe control system, the mainframe structure adopts a pre-tightened frame beam to ensure the strength of the system under oscillation pressure and the stability of the overall structure. The equipment is additionally provided with an oscillation hydraulic system with adjustable frequency and pressure. During the sintering process of workpieces, the oscillation pressure can achieve the slip rearrangement of particles. It adopts an overlay mode of dual hydraulic systems. Therefore, the accuracy of pressure control in the system is ensured.
