The cost of material is relatively low, and easily diversification of forms, makes that obtained furnishings are cheap, and pattern is various, can adapt to client's day
The esthetic requirement of benefit change, occupies the substantial amounts of market share.
However, the furnishings of majority can be with the direct skin contact of wearer when wearing, and existing metal alloy
Contain metallic nickel (Ni) in material mostly, nickel is a kind of sensitization metal, when the skin of wearer is closed with nickeliferous metal is adopted
During the furnishings directly contact that golden material makes, once contact position produces sweat, nickeliferous metal alloy compositions can discharge greatly
The nickel ion of amount, these nickel ions can be penetrated into inside the skin of wearer by pore and sebaceous glands, cause wearer's product
Life is allergic, redness, even itch, the phenomenon such as decortication occurs, and the duration of nickel allergy is long, the pressure suffered by allergy sufferers
The humidity of power, sweat, air and skin and friction can all increase the symptom of nickel allergy, and this can seriously threaten the body of wearer to be good for
Health, largely effects on the quality of furnishings, makes have larger limitation when making furnishings using existing metal alloy compositions
Property.
Content of the invention
It is an object of the invention to provide a kind of preparation method without magnetic without nickel metal furnishings, processing procedure is simple, production
Efficiency high, and yield is high, obtained will not cause without nickel metal furnishings without magnetic allergic.
For achieving the above object, the present invention provides a kind of preparation method without magnetic without nickel metal furnishings, including as follows
Step：
Step 1, provide raw material, raw material components and its weight portion as follows：Cobalt 30-35 parts, chromium 55-60 parts and molybdenum 5-10 parts；

Step 3, high-pressure molding；
Step 4, dumping degreasing；
Step 5, vacuum high-temperature sintering.
The furnishings include wrist-watch and ornaments.
Parts by weight of raw materials in the step 1 is respectively 9 parts of 33 parts of cobalt, 58 parts of chromium and molybdenum.
The powder of the step 2 is filtered using 400 mesh half tones.
In the step 3, paraffin, microwax, stearin candle and plastic cement are added to alloy powder, and is well mixed, then adopted
With dry-pressing, hot pressing or isostatic pressing.
Each material content of the step 3 is distinguished as follows by weight：With alloy powder as 1000 parts, paraffin 11-17
Part, microwax 11-17 parts, stearin candle 1-3 parts, plastic cement 65-75 parts.
The plastic cement is therein a kind of from PE, PP, HIPS, PET or which combines.
In step 4, the temperature of dumping degreasing is less than or equal to 500 DEG C.
In the step 4, heating base substrate to 480 DEG C -500 DEG C, wherein base substrate degreasing before temperature reaches 100 DEG C,
Temperature reaches 200 DEG C of plastic removals afterwards.
In step 5, sintering temperature is 1350-1500 DEG C.
Beneficial effects of the present invention：The present invention the preparation method without magnetic without nickel metal furnishings, by group be divided into cobalt,
After the raw materials melt of chromium and molybdenum, chilling dusts to form alloy powder, then through high-pressure molding, dumping degreasing and vacuum high-temperature sintering
The step of, it is obtained without magnetic without nickel metal furnishings, processing procedure is simple, and production efficiency is high, and product yield is high, simultaneously because alloyed powder
End is made up of cobalt, chromium and molybdenum, not comprising the nickel with sensitization, makes obtained to draw without nickel metal furnishings without magnetic
Rise allergic, with higher product quality.
Specific embodiment
The present invention provides a kind of preparation method without magnetic without nickel metal furnishings, and the furnishings include wrist-watch and decorations
The all types of furnishings such as product, the preparation method without magnetic without nickel metal furnishings comprise the steps：
Step 1, provide raw material, raw material components and its weight portion as follows：Cobalt 30-35 parts, chromium 55-60 parts and molybdenum 5-10 parts.
Preferably, the parts by weight of raw materials in the step 1 is respectively 9 parts of 33 parts of cobalt, 58 parts of chromium and molybdenum.
Step 2, by each raw material components melt, then chilling dusts, formed alloy powder.
Specifically, the powder of the step 2 is filtered using 400 mesh half tones.
Step 3, high-pressure molding.
Specifically, in the step 3, paraffin, microwax, stearin candle and plastic cement are added to alloy powder, and are well mixed,
