Zusammenfassung:The invention relates to the technical field of copper-tungsten contact preparation, in particular to a high-pressure ablation resistant Wf-CuCrW contact and a preparation method thereof. The preparation method comprises the following steps: preparing modified WCr fibers, preparing a W sheet, preparing a W ring sleeve based on a metal additive preparation method, and preparing a Wf-CuCrW contact based on an infiltration method. On the basis of a metal additive preparation process, the fiber-net-shaped W sheet is used as an additive to prepare the CuW contact, the use amount of an adhesive in the additive preparation process is greatly reduced, and then pores generated in a subsequent adhesive removal process are reduced; moreover, a W-CuCr layer capable of achieving component compensation is further designed, the inner and outer CuCr component concentration difference, caused by the infiltration gradient, of the contact is compensated, and the structure uniformity and the overall performance of the Wf-CuCrW c
