Abstract
The present invention discloses an anti-corrosion multi-element imitation gold colour cast copper alloy and a manufacturing method thereof. The cast copper alloy comprises the components according to weight percentages: 60 to 84% of Cu, 0 to 35% of Zn, 10.5 to 10% of Al, 0.5 to 15% of Ni, 0.1 to 8% of Mn, 0 to 5% of FeO, 0.01 to 15% of Ti, 0.001 to 5% of Ce and 0 to 8% of Sn, and is manufactured by a conventional casting method. The present invention utilizes chemical inert performance of several kinds of elements, or a compact inert protection film formed on the surface of the copper alloy to protect the colour of the imitation gold copper alloy from changing at atmosphere. The present invention utilizes the performance that some elements are easy to form metal oxides with elements which are easy to corrode and change colours, such as zinc, copper, etc. to inhibit the elements, such as zinc, copper, etc. from corroding in corrosive media, such as atmosphere or acid rain, etc. The present invention omits expensive metal of gold, and obtains 18K to 22K imitation gold. The processing surface and the non-processing surface of the present invention are both golden yellow, and are basically equal. The imitation gold cast copper alloy of the present invention has the advantage of atmospheric corrosion resistance, and can not change colour when immersed in a water solution with 4% of NaCl for two months. Besides, the present invention can be tolerant of the etching from 4 days and nights in a water solution with 1% of sulfuric acid, a water solution with 5% of sulfuric acid, a water solution with 10% of sulfuric acid, and a water solution with 20% of sulfuric acid.
Description
Technical field
The present invention relates to copper base alloy, relate in particular to corrosion-resistant multicomponent simulating golden colour casting alloy and manufacture method thereof that zinc is made time main component.
Background technology
In background technology, be used for the large-scale open-air copper relief in city, the bronze statue of indoor and outdoor display, artwork is generally with brass or bronze casting, this two Albatra metal-pours into a mould out appearance the black oxidation skin, though the economy-combat polishing is bright, expose to the sun and rain and acid rain but cannot stand, salt fog corrodes, even indoor, they are the meeting variable color in some months, verdigris appears in blackout at last, can't cast golden yellow, existing artwork, electrogilding is often used in their flavous acquisition, gold-decorated, gilding, plating titanium nitride, electro-coppering-zinc-methods such as Xi ternary alloy, gold-plated, the way of gold-decorated gilding needs expensive gold, though the method color and luster of plating titanium nitride picture gold, but not wear-resisting (as stainless steel surface plating TiN), the plating ternary copper-alloy is had to weak golden, and (about 14～18K) is not wear-resisting, more not anti-corrosion, just turns black in indoor 3～June.And because device-restrictive, ion plating and plating are not suitable for massive article.
Summary of the invention
The invention provides a kind of anticorrosion cast multi-element Cu-alloy simulating golden colour and manufacture method thereof, make the copper alloy color and luster, the erosion of anti-atmosphere (acid rain, salt fog) at 18K～22K simulating golden colour.
The component of anticorrosion cast multi-element Cu-alloy simulating golden colour of the present invention (% by weight) is:
Cu 60～84 Zn 10～35
Al 0.5～10 Ni 0.5～15
Mn 0.1～8 Fe≤5%, but be not equal to 0
Ti 0.01～15 Ce 0.001～5
Sn 0～8
Manufacture method: adopt precision-investment casting or permanent mold casting or sand mold casting.
The present invention utilizes the synergistic effect between several elements, makes the color and luster of copper alloy adjustable in 18K～22K scope, reaches imitative golden purpose; Utilize the chemical inertness of certain several element or form fine and close inertia protective membrane, the imitative gold copper nondiscoloration in atmosphere of protection at copper alloy surface; Utilize some element and zinc, copper etc. to be subject to lose the character that the oxidation stain element forms Intermetallic compound, suppress the corrosion of element in corrosive mediums such as atmosphere or acid rain such as zinc-copper.
The present invention compares with background technology, the beneficial effect that has is: the present invention has saved the such expensive metal of gold, and the simulating golden colour of acquisition 18K～22K, machined surface and non-machined surface all are golden yellow, basically identical, imitative gold copper atmospheric corrosion resistance of the present invention soaks nondiscoloration in two months in the 4%NaCl aqueous solution, etch 4 round the clock in ability 1%, 5%, 10%, 20% aqueous sulfuric acid.
