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