Abstract
The invention relates to a wear-resistant zinc alloy for manufacturing a water pump bearing bush, which comprises the following components in weight percent: 15 to 20 percent of aluminum, 2.5 to 5 percent of copper, 0.05 to 0.1 percent of magnesium, 0.05 to 0.1 percent of titanium, 0.05 to 0.15 percent of cerium, and the balance being zinc. Because rare earth elements are added to the alloy, the crystal structure of the zinc base alloy is changed, and the problem of decladding of an alloy coating layer of the water pump bearing bush is solved, thus the wear-resistant zinc alloy has the characteristics of high hardness, high intensity and high wear resistance.
Description
Affiliated technical field
The present invention relates to a kind of non-ferrous metal alloy material, particularly a kind of abrasion-proof zinc alloy of making water pump bearing insert belongs to the alloy material technology of preparing.
Background technology
At present, pasting one deck Babbitt metal on the internal layer surface of the body skin of water pump bearing insert, is the cohesive force of strengthening housing and Babbitt metal, the housing internal layer axially and radially be processed with three roads play stern notch, since ensure the stability of the Babbitt metal after pouring into a mould.Yet Babbitt metal is fitted on the body skin, and meeting is owing to two kinds of materials expands with heat and contract with cold than difference, and fully closely zero-clearance, even appearance shells so that the card machine shuts down and causes power failure.Accident such as cut off the water, influence is produced.
Summary of the invention
The objective of the invention is to overcome the above-mentioned deficiency of prior art, composition to existing zinc base alloy improves, provided a kind of abrasion-proof zinc alloy of novel manufacturing water pump bearing insert, be added with rare-earth element cerium in this zinc base alloy, make the crystal structure sex change of zinc base alloy, solve the problem of the alloy coated layer shelling of water pump bearing insert, also had hardness height, intensity is big, wear resistance is high characteristics.
The technical solution that the present invention provides is: the abrasion-proof zinc alloy of this manufacturing water pump bearing insert, to form by zinc, aluminium, magnesium, silicon, nickel and cerium, and the content of each component is respectively:
Aluminium 15-20%, copper 2.5-5%, magnesium 0.05-0.1%,
Titanium 0.05-0.1%, cerium 0.05-0.15%, all the other are the content of zinc.
The preparation of the abrasion-proof zinc alloy of this manufacturing water pump bearing insert that the present invention provides can be made by the melt that contains said components, and the production method that is adopted is not had special restriction.
Compared with prior art, the invention has the beneficial effects as follows: owing to added rare earth element, make the crystal structure sex change of zinc base alloy, solved the problem of the alloy coated layer shelling of water pump bearing insert, also have hardness height, intensity is big, wear resistance is high characteristics.
Embodiment
Embodiment:
The chemical ingredients (weight %) that adopts the induction oven process to smelt the zinc base alloy of output is:
Aluminium 18%, copper 3.6%, magnesium 0.08%, titanium 0.065%,
Cerium 0.1%, all the other are the content of zinc.
Claims (1)
1. an abrasion-proof zinc alloy of making water pump bearing insert is characterized in that being made up of zinc, aluminium, magnesium, silicon, nickel and cerium, and the content of each component is respectively:
Aluminium 15-20%, copper 2.5-5%, magnesium 0.05-0.1%,
Titanium 0.05-0.1%, cerium 0.05-0.15%, all the other are the content of zinc.
