Abstract
The invention relates to a copper base multielement alloy with good wearing resistance, consisting of copper, zinc, aluminium, magnesium, silicon, nickel, chromium, niobium and cerium. The content of all the components is as follows: 25 percent to 30 percent of zinc, 3 percent to 5 percent of aluminium, 0.25 percent to 0.5 percent of magnesium, 2 percent to 3 percent of silicon, 0.5 percent to 2 percent of nickel, 4 percent to 6 percent of chromium, 0.08 percent to 0.12 percent of niobium, 0.05 percent to 0.15 percent of cerium and the balance of copper. As rare earth element cerium is added, the copper base multielement alloy leads the crystalline structure of the copper base alloy to denature, solves the problem that the wear-resistant parts of the original machine have poor wear resistance, and also has the characteristics of high strength and good wearing resistance.
Description
Affiliated technical field
The present invention relates to a kind of non-ferrous metal alloy material, the good copper-based multicomponent alloy of particularly a kind of wear resistance belongs to the alloy material technology of preparing.
Background technology
Some wear-resisting spare parts of existing metallurgical equipment and mining building and digging operation equipment still adopt common copper base alloys such as tinbronze, xantal.Its wear resistance is relatively poor, and work-ing life is shorter, need often to change, thereby influence is produced.Therefore, improve the wear resisting property of these machine wearing pieces, both can improve the work-ing life of equipment, can guarantee the driving time of equipment again, reduce cost.So the good copper base alloy of wear resistance that development makes new advances is the task of top priority.
Summary of the invention
The objective of the invention is to overcome the above-mentioned deficiency of prior art, composition to existing copper base alloy improves, provided a kind of novel good copper-based multicomponent alloy of wear resistance, be added with rare-earth element cerium in this copper base alloy, make the crystal structure sex change of copper base alloy, solve the problem of machine wearing piece wear resisting property difference in the past, also had hardness height, characteristics that wear resistance is good.
The technical solution that the present invention provides is: the copper-based multicomponent alloy that this wear resistance is good, to form by copper, zinc, aluminium, magnesium, silicon, nickel, chromium, niobium and cerium, and the content of each component is respectively:
Zinc 25-30%, aluminium 3-5%, magnesium 0.25-0.5%, silicon 2-3%, nickel 0.5-2%,
Chromium 4-6%, niobium 0.08-0.12%, cerium 0.05-0.15%, all the other are the content of copper.
The preparation of the copper-based multicomponent alloy that this wear resistance that the present invention provides is good 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 be added with rare-earth element cerium, make the crystal structure sex change of copper base alloy, solved the problem of machine wearing piece wear resisting property difference in the past, 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 copper base alloy of output is:
Zinc 26%, aluminium 3%, magnesium 0.3%, silicon 2%, nickel 0.12%, chromium 5%, niobium 0.10%, cerium 0.085%, all the other are the content of copper.
Claims (1)
