Abstract

The invention relates to a high-temperature-resistant oxidation-resistant alloy. The high-temperature-resistant oxidation-resistant alloy is characterized by consisting of main components and auxiliary components, wherein the main components consist of the following components in percentage by mass: 10-25% of magnesium, 5-15% of aluminum, 10-15% of lithium, 1-3% of cobalt, 15-25% of nickel, 1-5% of vanadium, 1-2% of manganese, 0.5-1% of molybdenum, 0.5-1% of niobium and 0.5-1% of titanium; and the auxiliary components consist of the following components in percentage by mass: 20-30% of polypropylene, 1-10% of a lubricant and 1-10% of inorganic minerals, and the melt flow rate of polypropylene is 50g / min. The high-temperature-resistant oxidation-resistant alloy has the beneficial effects as follows: (1) the magnesium alloy is low in cost, and the production process is simple and easy to operate and control; (2) the magnesium alloy is good in corrosion resistance and high in strength, and has certain fire resistance; and (3) multi-component alloying is used in the technical scheme, and the high-temperature-resistant oxidation-resistant alloy which has the characteristics of good process stability, high-temperature resistance, wear resistance, oxidation resistance, impact resistance and the like is obtained by adjusting the proportion of the alloy, reducing components of a precious alloy, adjusting the production process and experimenting repeatedly.

Description

[0001] technical field [0002] The invention relates to the field of alloys, in particular to a high-temperature-resistant and oxidation-resistant alloy and a preparation method thereof. Background technique [0003] 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 limite...
