摘要： A hybrid preform component (100) including a plurality of elongated metallic cores (101) and a coating paste (102) is provided. The coating paste (102) envelops the elongated metallic cores (101). The coating paste (102) includes a first material having a first melting point, a second material having a second melting point, and a binder. A method (200) for treating a component (100) is also provided. The method (200) includes mixing a second material, a first material, and a binder to make coating paste (102). The method (200) further includes coating the cores (101) using the coating paste (102) to form a coated rod assembly. The method (200) further includes compressing the coated rod assembly to envelop the coating paste (102) to the cores (101) and form a preform component (100) having a near net shape. The method (200) further includes sintering the preform component (100) to form a pre-sintered preform.
