Abstract

The invention relates to an alloy material with wear-resistance, heat-resistance, corrosion-resistance, high hardness. The alloy is composed of, in wt%, 1.3-1.8 of C, 19-23 of Cr, 13-17 of W, 2.5-3.5 of B, 1-3 of Si, less than or equal to 5.0 of Fe, 5.0 of Ni, and the balance being Co and impurities caused by smelting processes. The alloy material relates to cobalt-based alloy, can ensure good performances of wear-resistance and corrosion-resistance, has relatively low cost, and is suitable for applications in the fields of mining machinery, metallurgical industry, national defense and military, etc.

Description

Technical field [0001] The invention relates to an alloy material, specifically an alloy material with wear resistance, high temperature resistance, corrosion resistance and high hardness. The high-hardness alloy material still has excellent mechanical properties and corrosion resistance at a high use temperature of 1000°C. Background technique [0002] Cobalt-based or nickel-based superalloys are known in the prior art, and they have good material strength under high temperature conditions. Compared with nickel-based superalloys, cobalt-based alloys often have improved heat and corrosion resistance, as well as higher wear resistance and oxidation resistance. [0003] The cobalt-based alloys currently produced are mainly composed of cobalt-chromium-tungsten-carbon quaternary alloys. Although they have good wear resistance and corrosion resistance, they can be used in various acidic, oxidizing, and electrochemical corrosion media. Poor. Moreover, the mechanical properties of thes...
