Abstract

The invention discloses a high-strength magnesium alloy material and a preparation method thereof. The high-strength magnesium alloy material is prepared from, by weight, 60-65 parts of magnesium powder, 15-25 parts of zirconium silicide, 2-8 parts of tin powder, 4-9 parts of tungsten carbide powder, 10-20 parts of fluoride magnesium stone powder, 3-8 parts of tourmaline powder, 4-9 parts of smithsonite powder, 6-8 parts of germanium dioxide, 3-6 parts of potassium oxide, 4-8 parts of yttrium oxide and 3-5 parts of oleic acid. The high-strength magnesium alloy material prepared according to the method is superior to similar products on the market in terms of strength, hardness, abrasion resistance and corrosion resistance, and the service life of an alloy part is prolonged. In addition, easiness in raw material acquisition, low processing cost, technical simplicity in preparation, easiness in parameter control, safety and environment friendliness in production and suitableness for large-scale industrial production are realized.

Description

Technical field [0001] The invention specifically relates to a high-strength magnesium alloy material and a preparation method thereof. Background technique [0002] Metallic materials refer to composite materials that use metal or alloy as a matrix and fibers, whiskers, particles, etc. as reinforcements. According to the different base metal used, the temperature range is 350~1200℃. Its characteristics in terms of mechanics are high transverse and shear strength, good comprehensive mechanical properties such as toughness and fatigue, and it also has thermal conductivity, electrical conductivity, wear resistance, low thermal expansion coefficient, good damping, no moisture absorption, no aging and no pollution Etc. Metal matrix composites can give full play to the respective advantages of the component materials, realize the optimal configuration of each component material resource, save precious metal materials, and realize the performance requirements that a single metal cann...
