Abstract

The invention discloses a device for manufacturing a progressive interface of a heterogeneous material and a control method, and relates to the technical field of laser additive manufacturing. The mixing uniformity of components in a heterogeneous material transition region is remarkably improved, and the size and distribution uniformity of grains and a brittle second phase in a heterogeneous interface transition region are reduced, so that the mechanical property of a heterogeneous material connection region is remarkably improved. And meanwhile, the double-barrel powder feeder and the spiral powder mixing stirrer are adopted, uneven mixing caused by large density difference of heterogeneous materials is avoided, online real-time adjustment and conveying of the metal powder in the progressive mixing proportion can be achieved, and cracking caused by interface component mutation due to component gradient step length of the mixed powder is avoided. On the basis, progressive transition of titanium alloy-transition interface-aluminum alloy components is formed, effective connection of heterogeneous materials with large physical property parameter differences is achieved, and then integrated composite forming of the heterogeneous alloy and large complex structural parts can be achieved.
