Description
Technical field
The invention belongs to field of alloy material, and in particular to a kind of ornament colour alloy material.
Background technique
Existing jewellery are made with gold, platinum or silver mostly, these noble metals are since Traditional Factors are in state
It is interior that there is large market, but more focus on appearance, the style of ornaments in European & American Market, and pay no attention to the value of ornaments material.It passes
Gold, silver quality of uniting is softer, is easily deformed, be not suitable for it is more complex inlay, welding processing；It can also aoxidize for a long time, lose light
Pool；Make ring using other metals, it is too heavy such as pure tungsten, pure titanium it is too light etc.；Also the ring of useful nonmetallic materials production
Refer to as used stone material or jade, the disadvantage is that: frangible and style is single.1600 DEG C of the sintering temperature of traditional tungsten steel ring, wolfram steel
The conventional sintering time of ring is 30 hours, and for energy angle, consumption of heat energy is big；Meanwhile the change of conventional sintering ring
Shape amount is low, and the process costs of cold working are high, and the workpiece of conventional sintering is greater than the contraction of horizontal direction in the shrinkage ratio of vertical direction
It is more unbalanced than, shrinkage ratio, therefore the qualification rate of product is made to be extremely difficult to 90% or more.And tungsten steel ornament only has canescence a kind of
Other non-ferrous metals need to be electroplated in color, other colors.The non-ferrous metal of plating is easy to wear, and ornaments service life is by electroplated layer shadow
It rings.
Tungsten alloys most at present is all applied industrially, with the raising of people's lives level, the demand of aesthetic conceptions,
Jewellery, ornaments material since developing to the noble metals such as traditional jade and gold, silver, palladium, platinum apply tungsten alloy material.The U.S.
Patent US6928734 has registered a kind of method for preparing ring shaped jewelry with tungsten alloy.Which disclose by weight percentage
Amount composition are as follows: tungsten carbide 50-90；Bonding agent nickel 2-10；Cobalt 1-2 and chromium carbide 0.5-3.As it can be seen that the patent is disadvantageous in that:
Firstly, the ornaments are only limitted to ring shaped jewelry；Secondly, being then that tungsten carbide lower limit is too low.If tungsten carbide accounts for 50%, the material of configuration
The requirement of tungsten alloy jewellery has been not achieved.Its hardness is decided by the number of hard phase tungsten carbide.Tungsten carbide is lower than 70%, there is no
High rigidity, wearability are lost the characteristic of tungsten alloy jewellery；Third, the patent tungsten alloy material color is single ash
White is unable to satisfy the diversity requirement of existing market.
Based on above-mentioned analysis, a kind of density, hardness are high, porosity is low, and ornaments heavy feeling is stronger, while having golden yellow coloured light
Pool still has good color after any processing, and jewelry surface is not easy to wear, and glossiness is good after ornaments are polished, and texture is thin
Greasy, processing performance is excellent, the huge market demand ornament colour alloy material is that current European & American Market is salable.
Summary of the invention
It is made the purpose of the present invention is to provide one kind for ornament and density, hardness height, porosity is low, ornaments are thick and heavy
Still there is good color after feeling stronger any processing, jewelry surface is not easy to wear, and glossiness is good after ornaments are polished, texture
Exquisiteness, the excellent production bracelet of processing performance, colored alloy material of ring and preparation method thereof.
In order to achieve the above object, the invention adopts the following technical scheme:
