Abstract

The invention relates to a self-lubricating wear-resistant damping alloy and a preparation method thereof. The alloy takes a magnesium alloy as a matrix and is characterized in that compound complexes are uniformly distributed on the magnesium alloy matrix; the alloy material comprises the following chemical components by weight percent: 6-8% of aluminium, 2.5-3% of strontium, 2-3% of tin, 1-2.5% of iron, 0.03-0.09% of carbon, 0.3-0.5% of graphite, 0.1-0.3% of manganese, 0.5-1.2% of nickel, 0.01-0.03% of molybdenum, 0.03-0.05% of boron, 0.03-0.05% of vanadium, 0.001-0.003% of tellurium, 0.8-1.2% of dysprosium, 1.2-1.5% of yttrium, 0.8-1.2% of lanthanum and the balance of magnesium and less inevitable impurities.

Description

Technical field [0001] The invention belongs to the field of functional metal alloy materials, in particular to a self-lubricating wear-resistant shock-absorbing alloy and a preparation method. Background technique [0002] At present, in the field of metal materials, the use of magnesium alloys as wear-resistant and shock-absorbing materials has received widespread attention. The prior art proposes to add zinc, yttrium, and zirconium to magnesium to produce magnesium-based alloys, but this technology requires yttrium and zirconium It is added in the form of magnesium-30% yttrium and magnesium-30% zirconium respectively, and a magnesium alloy with high shock absorption is prepared through preheating, smelting and forming. However, the preparation method of this material has strict element control and limited improvement in shock absorption. At the same time, the wear resistance of ordinary magnesium alloys is not high. Summary of the invention [0003] The purpose of the present ...
