AI Technical Summary
Technical Problem
The presence of pores in existing additively manufactured alloy parts affects the material's density and strength, thus hindering the large-scale promotion and application of additive manufacturing technology.
Method used
By adjusting the vibration frequency to 50-60 Hz on the vibration device, alloy parts are prepared using coaxial powder feeding laser energy deposition. A 50-60 Hz vibration field is provided by a variable frequency vibration motor to eliminate bubbles in the molten pool and remove internal pores.
Benefits of technology
It improves the density and mechanical properties of alloy parts, prevents molten pool collapse, and enhances the quality of additive manufacturing.

Abstract
本发明公开了一种用于消除激光增材制造合金内部孔洞的方法，包括如下步骤：步骤1：将增材制造的基板固定在振动装置上；步骤2：调节振动装置振动频率为50—60赫兹；步骤3：在基板上采用同轴送粉激光能量沉积方式制备合金零件；该方法在增材制造过程中通过振动装置给基板上的零件熔池施加一个50—60赫兹振动场，让熔池中的气泡能够及时的排出，从而消除了合金零件孔洞，提高了合金零件的致密性，且熔池不会坍塌；本发明还公开了一种用于消除激光增材制造合金内部孔洞的装置。
