Abstract

The invention discloses a zinc base alloy and a preparation method thereof, and relates to a zinc base alloy taking aluminum as a secondary principal component. The zinc base alloy is a Zn-Al-Cu-Ba-Mg-La-Ce zinc base alloy which comprises the elementary components, by mass percent, 5.5-7.5% of Al, 2.5-4.5% of Cu, 3.5-5.5% of Ba, 0.011-0.016% of Mg, 0.13-0.17% of La, 0.22-0.29% of Ce, and the balance Zn. Ba is added to Zn-Al-Cu-Mg molten metal, then LaBr3 and CeBr3 are added for modification treatment, and then AlCl3 is used for refining treatment, thus the high-intensity wear-proof Zn-Al-Cu-Ba-Mg-La-Ce zinc base alloy is obtained. The defects that the prepared zinc base alloy is thick and big in grain structure, the impurity content is high, the mechanical property is poor, and environmental pollution and potential safety hazards are caused in the preparation process in the prior art are overcome.

Description

technical field [0001] The technical solution of the invention relates to a zinc-based alloy with aluminum as the secondary main component, specifically a zinc-based alloy and a preparation method thereof. Background technique [0002] Zinc-based alloy is a new type of metal alloy material that has been developed rapidly and widely used in recent decades. It belongs to the category of non-ferrous metal alloys. The emergence of different types of zinc-based alloys has greatly improved the selectivity of engineering materials. Due to its unique physical and chemical properties, zinc-based alloys have obvious performance advantages in the application of non-ferrous metal alloys. First, due to the extremely low melting point of zinc-based alloys (the melting point of pure zinc is only 419.5 ° C), it can be used in zinc The smelting and processing of zinc-based alloys can save a lot of energy consumption; secondly, in the actual application process, zinc-based alloy materials can...
