Description

technical field [0001] The invention belongs to the technical field of hard alloys, and in particular relates to a ruthenium-containing hard alloy material and a preparation process thereof. Background technique [0002] Cemented carbide is a kind of cermet material made by powder metallurgy process of hard compound of refractory metal and bonding metal. Cemented carbide has a series of excellent properties such as high hardness, good wear resistance, high strength, heat resistance, and corrosion resistance, especially its high hardness and wear resistance, which remain basically unchanged even at a temperature of 500°C. It still has high hardness at 1000°C. Cemented carbide is widely used as tool material, such as turning tools, milling cutters, reamers, drills, boring tools, etc., for cutting cast iron, non-ferrous metals, plastics, chemical fibers, graphite, glass, stone and ordinary steel, and can also be used for Cutting heat-resistant steel, stainless steel, high man...
