Description
Technical field
The present invention relates to bullion manufacture technology fields, and in particular to a kind of artwork Ornament production of ceramic inserts metal
Method.
Background technique
Ceramics have its distinctive material characteristic and history culture inside information as a kind of unique artistic medium language.From material
For expecting angle, ceramics have a mild quality, changeable muffle painting, and skin texture abundant is high rigidity, wear-resisting, acidproof, alkaline-resisting, resistance to
The superior functions such as cold, heat-resisting become a kind of material of unique feature in artwork Ornament.However, traditional ceramics material crystal structure
With apparent directionality, sliding system is considerably less, is nearly free from plastic deformation under external force, and Chang Chengxian brittleness is disconnected
It splits.When merely carrying out manufacture craft ornaments using ceramic material, decorative effect has biggish limitation.Using with a certain toughness
High technology ceramics material, and by the combinations of materials such as ceramic material and metal, synthetic cut stone, become the important development of ceramic jewelry exploitation
One of direction.
In existing ceramic jewelry production, substantially formed using single ceramic material by high temperature sintering.For example, specially
Benefit 201711362661.9 discloses a kind of ceramic ornament process for making, and basic process includes production green body, molding, system
Base dries in the shade, repaired biscuit, biscuiting, glazing, wipes bottom, puts coloured glaze, high temperature sintering, mill bottom, is made with dual-surface stereo pattern, two-sided extension
The ceramic ornament of glaze.Patent 201410278496.9 discloses a kind of processing molding method of high technology ceramics ornaments, it first will be smart
Close ceramics main material is ground into nanoscale powder, and binder is added in the powder, blank is obtained after injection molding, blank dries
Molded blank is made by degreasing and low-temperature sintering, then carves moulding in molded blank, pottery is finally made after high temperature sintering
Porcelain ornaments.Patent 201310453182.3 describes a kind of ceramic jewelry and preparation method thereof, it is by kaolin, calcite, oxygen
Change aluminium, magnesia, talcum powder, zinc oxide, colorant etc. to be uniformly mixed, after the thawing of high temperature Cinker clew furnace, molten slurry is poured into spherical shape
Spheres of ceramic is obtained in mold, then is processed into jewellery with spheres of ceramic.But the ceramic jewelry of these methods production, no matter from
For decorative effect, material value or energy consumption environmental-friendly, it is difficult to jump out the scope of traditional cheap ceramic.
Around decorative effect and the technique value for promoting ceramic jewelry, industry has carried out some research and explores.For example, specially
Benefit 201120326282.6 describes a kind of drum-shaped ceramic jewelry inlaid with gold, its arc-shaped surface among drum type ceramic body waist is arranged
Annular groove, the mosaic gold waist hoop in groove obtain ceramic jewelry inlaid with gold.This method improves the decorative effect and material of jewellery
Expect technique value, still, since ceramic material hardness is very high, difficulty of processing is very big, and is fragile material, cannot directly use
It carrys out embedded with metal as base material, can only be using the fixed metal of method of gluing, or the metal that selection ductility is excellent
It is welded and fixed again after the insertion of material use mechanical force.Patent 201610886035.9 discloses one kind and inlays in zirconia ceramics
The method of sapphire glass, using injection moulding method the ceramic green with mosaic site is made in zirconia ceramics by it,
The surface of mosaic site coats one layer of glass phase silica, then sapphire glass is placed in mosaic site, burns in sintering furnace
Form type and is formed and inlay effect.But the technics comparing of this method is cumbersome, fabrication cycle is longer, and there are green compact and glass
The problem of glass assembly is difficult or ceramics may fall off with glass.
