Description
Technical field
The present invention relates to technical field of alloy, specifically, being related to a kind of billon.
Background technique
From ancient times to the present, proof gold jewellery are very popular, not only because it can fully demonstrate the plentiful and luxurious of owner,
And value preserving effect is big.Currently, the demand of annual gold ornaments material accounts for about 80 % of golden total demand.Proof gold jewellery color beauty
It sees, corrosion resistance and anti-discoloration are good, but hardness is low, is easily deformed, and wears no resistance, and surface is easily worn, delineates, and cause gold
Loss, influences its finish.Therefore, Jewel inlaying jewellery can use karat gold, i.e., alloying element is added in proof gold, golden conjunction is made
Gold to improve intensity, the wearability of jewelry gold alloy, and adjusts the color of billon.
Gold ornament can be divided into proof gold ornaments, karat gold ornaments, plating gold ornaments and 4 major class of object of imitation gold.Proof gold jewellery are in China
Prevalence is with a long history for a long time.However, in recent years, with the progress of science and technology, new technology, new process are not
Disconnected application, there has also been very big development for gold jewelry manufacturing industry.Past has not been existed by the situation that proof gold jewellery rule all the land.
Not only glossy brilliant proof gold jewellery currently on the market, there are also up-and-coming youngster and colorful, gorgeous luxurious karat gold jewellery,
And the latter has greatly the gesture contended for supremacy and dominated.
Karat gold is alloy made of gold and other metal alloyings.Due to other metals type and incorporation ratio not
Together, karat gold shows different colors, such as red, green, grey, blue, black are rich and varied.According to gold content
Difference, karat gold is divided into 18K, the plurality of specifications such as 14K again.Karat gold jewellery win many with bright color elegance and variation in moulding multiterminal
The favor of consumer.It is the most popular with 18K jewellery in karat gold jewellery at home at present.And if at abroad, style fashion, uniqueness,
In addition to the jewellery of 18K, 14K even 9K, the jewellery of 8K all become the object that people rush to buy.
Karat gold fashion gold jewellery is broken through traditional design, by its distinctive material, colourful color change and novelty, is overstated
, bold personalized designs, by young man institute fanaticism high praise.And different modern womans can therefrom find and show oneself
Individual character, the karat gold jewellery for being suitble to different occasions.The protean moulding of karat gold jewellery, unique individual character bright characteristics, often by fashion
Personage is used to sufficiently show charisma.In American-European, Japan and other countries and area, the changeful karat gold jewellery of color gradually at
For fashion, and becomes people and show self, show being preferably selected for individual character.Some styles are modish, good luster, technique are fine
Brand karat gold jewellery even it is more taller than the price of solid gold jewelry.
In recent years, domestic karat gold jewellery scientific and technological content was higher and higher, had cultivated a large amount of outstanding Jewelry Design teachers and jewellery
With lapicide, electroplating technology work, processing and fabricating level is continuously improved, and technique is more and more exquisite, careful, or using whole polishing
Technology, or combined with sandblasting, pierced process, or mirror carves skin texture or engraves smooth lines on smooth surface, thus plus
No matter the three-dimensional stereopsis of strong jewellery and hierarchical space sense, have distinguished effect in terms of which angle.
On the one hand the addition of karat gold ornaments alloy element improves the hardness of gold ornaments, to be suitble to the various gemmy head of production
On the other hand decorations can also change the colors of karat gold ornaments by changing the ratio of the type of its ingredient.The color of karat gold in addition to
Yellow, white also have the type of grey with outside red.Traditionally, the bule gold formed when iron is added in gold just has
There is the color of grey.But regrettably, the addition of iron will form intermetallic compound.But due to the generation of ordering
With the generation of stress, which is extremely easy brittle failure at room temperature.It is easy to break just as dried firewood when serious, it does not show tough
The mechanical property of the excellent precious metal alloys of plasticity.This brittle fracture and the generation of crackle are not only in jewellery manufacturing process
It can generate, can also occur suddenly in the use process of jewellery.Frequent can find many places after the casting of jewellery manufacturing shop
Crackle, and incision position does not have any plastic deformation, and typical brittle fracture is presented, and factory's daily life of a family is stranded by this problem
It disturbs.The perception of such material is not only affected, the market sales volume and marketing of such material are also seriously reduced.
Although the absolute number of China's jewelry and decoration industry in quantity and yield is larger, scope of the enterprise is small, core
Heart competitiveness is not strong.In development process, jewelry enterprise is not innovated during productive accumulation usually as processor,
Form out the characteristic of oneself.For a long time, most domestic jewelry enterprise all rests on the OEM form of order processing, makes
With the production line of oneself, the product of oneself is produced, finally but sticks other people brand.It is first even some biggish enterprises
Decorations and the critical material of trim-alloy production but almost rely on import, are almost one in terms of Novel decoration material development
Piece blank.Therefore, research and development and industrialization high-performance karat gold material with independent intellectual property rights and its technology of preparing, for enhancing
The competitiveness of China's jewelry and decoration industry will have the function of very positive.
Summary of the invention
The purpose of the present invention is to overcome the deficiency in the prior art, provides the corrosion-resistant jewellery material 10K ash gold of rub resistance and closes
Gold and its technique.
To achieve the goals above, the present invention adopts the following technical scheme that：
Rub resistance corrosion-resistant jewellery material 10K ash billon and its technique.By weight percentage, the group of alloy becomes Li:
0.4-0.6wt.%,S:0.2-0.3wt.%,Ca:1.2-1.8wt.%,In:1.4-1.8wt.%,Co:20.0-24.0wt.%,Fe:
15.0-18.0wt.%,Au:41.0-42.0wt.%, surplus are silver.
Above-mentioned rub resistance corrosion-resistant jewellery material 10K ash billon and its preparation method of technique, include the following steps：
As above the raw material matched is added in the electric induction furnace of argon gas protection, and uses graphite crucible;Low stream is used after metal molten
The argon gas of amount is protected, and big air-flow is avoided to make the serious scaling loss of alloying element;10 minutes are kept the temperature at 1200 degree when melting, leans on high frequency sense
Answer furnace electromagnetic agitation uniform;1 minute, which is kept the temperature, at 1200 degree after mixing evenly and is cast comes out of the stove;Billon casting uses diameter 50-
The punching block of 100mm, and cooled down by the way of water cooling.Resulting ingot casting is rolled at room temperature, rolling lower amount per pass is
30-40%;It is 380 degree per intermediate anneal temperature after rolling twice, keeps the temperature 0.5 hour;Finally material is rolled into a thickness of 10-
The golden plate of 20mm;It in jewellery forming process, needs to carry out intermediate annealing process, eliminates the stress in process;Wherein,
Homogenizing temperature is 350 degree, and the time is 1-2 hours.
Compared with prior art, the present invention has the advantages that：
（1）Traditionally, the bule gold formed when iron is added in gold just has the color of grey.But it is unluckily
It is that the addition of iron will form intermetallic compound.But due to the generation of the generation of ordering and stress, the material is at room temperature
Extremely it is easy brittle failure.It is easy to break just as dried firewood when serious, the mechanics of the excellent precious metal alloys of toughness plasticity is not shown
Performance.This brittle fracture and the generation of crackle can not only generate in jewellery manufacturing process, in the use process of jewellery
Also can occur suddenly.The frequent crackle that many places can be found after the casting of jewellery manufacturing shop, and incision position does not have any modeling
Property deformation, typical brittle fracture is presented, factory's daily life of a family is perplexed by this problem.Not only affect the sight of such material
Sense, also seriously reduces the market sales volume and marketing of such material.This patent is by advanced materialogy technology to K ash
Gold has carried out multi-faceted innovation and raising.That is, it solves the face that the golden material of field of jewelry K ash is difficult to take into account
The status that color, corrosion resistance and processing performance cannot obtain simultaneously.
（2）The alloy has close to eutectic structure, possesses optimal etch resistant properties and Deformation Properties of Al.After casting

It is short, energy and material consumption is low, tissue be easy to control.As alloy content is in the variation of optimization range, the mechanical performance of the alloy can be with
Significantly adjusted.Meanwhile the alloy due to liquidus curve it is relatively low, thus be suitable for casting.Since crystal grain obtains carefully
The technical problems such as hot cracking tendency is big when changing, and solving solution casting, and casting cavity is low with loose obvious product yield rate, because
And it has a vast market foreground.
（3）The corrosion potential of the alloy is higher than the corrosion potential of traditional grey karat gold, thus is being subjected to corrosive environment
The lower material can show lower corrosion rate.Meanwhile the corrosion current of the material is the 0.2- of traditional grey karat gold
0.4 or so.The salt spray resistance of the grey karat gold, resistance to sulfur dioxide and hot resistance test performance are better than traditional karat gold, corrosion-resistant
There are clear superiorities for ability.Select the alloying element being added in alloy that can form passivating film on surface, thus to ambient enviroment
Corrosion plays a protective role.This film is in different media, since unpolarizing is as a result, different resistance to show
Corrosive nature is also more stable to the corrosion resistance of strong acid, strong basicity sweat.The jewellery of material preparation are worn in normal human body
There is no metachromatisms in environment lower 10 years.
（4）The alloy solves traditional grey karat gold casting fluidity deficiency, and yields is low, and the presentation quality on surface is not good enough,
Surface is easy to appear the casting flaws such as streamline trace, spot, loose, it is difficult to ensure that the bright and clean smooth quality requirement of product surface,
And very big surface dressing work load is brought, increase production cost.In addition, the product also has excellent mechanical property
Can, tensile strength can achieve 200-250Mpa, and elongation percentage has reached 30-40%.In addition, final products also have it is excellent resistance to
Grind performance.Under the conditions of sufficient lubrication, coefficient of friction 0.01-0.02 is not 0.04-0.08 under lubricating condition.Wearability is big
Amplitude improves.Using the material preparation jewellery after normal use 10 years, surface be not in scratch or fade the phenomenon that.
