Abstract

The invention relates to a composite material containing a high-entropy alloy coating on the surface and a preparation method of the composite material, and belongs to the technical field of surface composite materials. The preparation method of the composite material with the surface containing the high-entropy alloy coating comprises the following steps that firstly, the surface of an evanescent mode model is coated with coating liquid, drying is conducted, and a model with the coating is obtained; and then carrying out lost foam casting on the molten steel by adopting a model with a coating. The preparation method of the composite material containing the high-entropy alloy coating on the surface is simple in process, short in production period and low in cost. When molten steel is subjected to lost foam casting, metal powder on the surface of a lost foam model can be subjected to metallurgical reaction with iron elements in the molten steel, a FeCoCrNi series high-entropy alloy coating is formed on the surface of a base body formed after the molten steel is cooled in situ, good metallurgical bonding is achieved between the coating and the base body, and cracks are not prone to being generated between the high-entropy alloy coating and the base body.

Description

technical field [0001] The invention relates to a composite material with a high-entropy alloy coating on the surface and a preparation method thereof, belonging to the technical field of surface composite materials. Background technique [0002] Conventional alloys generally consist of a metal element as the main element and alloying elements in minor amounts. The purpose of adding alloying elements is mainly to meet the requirements of the alloy for some special properties. However, limited by the traditional design concept, the structure and performance of traditional alloys are limited by the main elements. Therefore, the basic properties of the main elements set a ceiling for the performance improvement of alloys. The properties of the alloy can be improved by adding special alloying elements. For example, high-chromium cast iron is one of the common metal wear-resistant materials, and its high wear resistance is mainly due to the presence of a large amount of Cr in t...
