A high-strength, wear-resistant and corrosion-resistant molybdenum-based composite material and a preparation method thereof

Abstract

The invention discloses a high-strength, wear-resistant and erosion-resistant molybdenum-based composite material and a preparation method thereof in the field of metal-based composite material technology, comprising the following steps: step 1, preparing the raw materials of the following components: 91-93 parts of Mo powder, 0.1-0.8 parts of Ti powder, 0.01-0.2 parts of Zr powder, and 2-20 parts of TiB2 powder; step 2, mixing the raw materials in step 1 for 4-20 hours to obtain a mixed raw material; step 3, treating the mixed raw material by a spark plasma sintering process or a cold isostatic pressing + high-temperature sintering process to obtain a high-strength, wear-resistant and erosion-resistant molybdenum-based composite material. The molybdenum-based composite material prepared by the present invention improves the density, hardness, high-temperature creep resistance, friction and wear resistance, and erosion resistance of the molybdenum-based composite material as a whole.
