Abstract

The invention discloses a ceramic-metal reinforced composite material, which comprises the components of (by weight percentage) 60-90% of Cr3C2, 10-40% of Ni, 1.4-1.6% of TiN, 0.4-0.8% of NiP, 2-5% of Nb, 1-5% of W, 5-10% of WC. The advantages of the material include high compression strength, high hardness and high oxidation resistant property.

Description

(1) Technical field [0001] The invention relates to a composite material, in particular to a metal-ceramic composite material with high strength, high hardness and high temperature oxidation resistance. (2) Background technology [0002] At present, alloy steel is mainly used in the manufacture of non-ferrous metal pipe hot extrusion molding, profile hot processing molds, and worm gear discs. Taking the manufacture of hot extrusion mold cores as an example, 3Cr2W8V alloy steel is mainly used. This traditional alloy The disadvantages of steel materials are: [0003] 1. Severe high temperature oxidation; [0004] 2. During use, the high-temperature strength and bending strength drop sharply at 700°C, and only 17-21 knots can be extruded, which reduces the service life of the mold. (3) Contents of the invention [0005] The technical problem to be solved by the invention is a cermet composite reinforced material with high compressive strength, high hardness and high high te...
