Description
technical field [0001] The invention relates to the field of alloys, in particular to a wear-resistant alloy and a preparation method thereof. Background technique [0002] Magnesium is the lightest structural material, which meets the requirements of environmental protection and energy saving such as low energy consumption, so it is often used to prepare alloys in industrial fields such as automobiles, electronics, and aviation. However, magnesium has a low melting point and is easy to burn. Therefore, the alloy prepared from magnesium is easy to burn itself when the temperature is close to its ignition point, causing a fire hazard. At present, the commonly used materials for preparing flame retardant functions are divided into three types: composite type, coating type and interlayer type. However, most of the flame retardants are toxic substances, and the application range of the alloy prepared by this method is severely limited. Although magnesium alloys are sought afte...
