Novel direct connection method for high-chromium white wear-resistant cast iron part and metal part

The invention provides a method for connecting a high-chromium wear-resistant white cast iron part with a metal part, the high-chromium wear-resistant white cast iron part is connected with the metal part to be connected by adopting an electric welding method, and the mass of carbon in the high-chromium wear-resistant white cast iron part accounts for 6-10% of the total mass of the part. Unique powder is mixed and processed into a porous green body, and then the high-chromium white wear-resistant cast iron part is prepared through liquid forging and infiltration processes. According to the method, the high-chromium wear-resistant white cast iron part can be directly connected with other metal parts to be connected through an electric welding method, use of the high-chromium cast iron is greatly promoted, and the actual application range of the wear-resistant high-chromium wear-resistant white cast iron part is effectively widened. The carbon content of the component can reach 6% or above, and the toughness va
