Embodiment 1

[0019] A zinc alloy material consisting of the following components according to mass percentage: 7.2% iron, 1.65% copper, 1.31% nickel, 0.42% tungsten, 0.19% ruthenium, 0.077% vanadium, 0.28% cobalt, 0.045% beryllium, and the balance is zinc.

[0020] A preparation method of zinc alloy material, comprising the following steps:

[0021] 1) Put iron, copper, tungsten and nickel into the crucible of the vacuum melting furnace, and evacuate to 8×10 -2 Above Pa, start to heat up. After the temperature rises to 800°C, stop vacuuming and fill the vacuum melting furnace with inert gas to 4×10 4 Pa; then continue to heat up to 950°C to form an alloy liquid, fill the alloy liquid with an inert gas and stir for 35 minutes, cool the alloy liquid to obtain an intermediate alloy;

[0022] 2) Add the master alloy, vanadium, ruthenium, cobalt, and beryllium into the crucible of the vacuum melting furnace, and evacuate to 8×10 -2 Above Pa, start to heat up. After the temperature rises to 8...

Abstract

The invention discloses a zinc alloy material. The zinc alloy material is prepared from, by mass, 5.2%-8.25% of iron, 1.25%-2.1% of copper, 1.15%-1.4% of nickel, 0.32%-0.52% of tungsten, 0.12%-0.23% of ruthenium, 0.06%-0.09% of vanadium, 0.23%-0.39% of cobalt, 0.02%-0.06% of beryllium and the balance zinc. The invention further discloses a preparation method of the alloy material. The zinc alloy material is high in mechanical hardness, good in abrasion-resisting effect, extremely excellent in tenacity and extremely suitable for certain mechanical parts having special requirements for the mechanical performance; the zinc alloy material is light, low in cost and quite suitable for application and popularization.

Description

technical field [0001] The invention relates to a zinc alloy material and a preparation method thereof, belonging to the field of alloy manufacturing. Background technique [0002] Zinc alloy is an alloy composed of zinc and other elements. Often added alloying elements are aluminum, copper, magnesium, cadmium, lead, titanium and other low-temperature zinc alloys. Zinc alloy has a low melting point, good fluidity, easy welding, brazing and plastic processing, corrosion resistance in the atmosphere, and the residual waste is easy to recycle and remelt; but the creep strength is low, and it is prone to dimensional changes caused by natural aging. Prepared by melting method, die-casting or pressure processing. According to the manufacturing process, it can be divided into cast zinc alloy and deformed zinc alloy. [0003] Whether it is cast zinc alloy or deformed zinc alloy, in the production process of some products, certain requirements are put forward for wear resistance a...
