Abstract

The invention discloses wear-resistant and corrosion-resistant alloy for a lining plate and a preparation method of the wear-resistant and corrosion-resistant alloy. The alloy comprises a main component, an auxiliary component and the balance of iron and impurities, wherein the main component comprises, by weight percentage, 0.1-0.3% of molybdenum, 0.1-0.8% of vanadium, 0.5-0.8 parts of titanium, 1-3% of cobalt, 1-3% of nickel, 1-1.5% of manganese, 0.2-0.4% of yttrium, 0.2-0.4% of tungsten and 0.9-1.8% of indium; the auxiliary component comprises, by weight percentage, 5-10% of thermoplastic resin, 1-3% of lubricating agent and 1-3% of inorganic mineral, and the melt flow rate of the thermoplastic resin is 60g / minute. The wear-resistant and corrosion-resistant alloy can increase the toughness, wear resistance and impact resistance of the lining plate so as to prolong the service life of bucket teeth.

Description

technical field [0001] The invention relates to the technical field of metal materials, in particular to a wear-resistant and corrosion-resistant alloy for lining plates and a preparation method thereof. Background technique [0002] After more than 30 years of development, the liner material has experienced the development of high manganese steel, ordinary white cast steel, nickel hard cast iron, high chromium white iron, modified high manganese steel and medium and low alloy steel with various quenching and tempering processes stage. At present, in domestic practical applications, high manganese steel is still dominant. Among several mainstream materials, high manganese steel has good toughness, but its wear resistance and corrosion resistance are not ideal; high chromium cast iron has good wear resistance, but its toughness is low. Poor; the brittleness and corrosion resistance of medium and low alloy steels are not up to standard. It is necessary to research and develo...
