The purposes of product, prepared prepared by a kind of novel production process of forging type joint prosthesis and metallic article
Rough forging is used to forge medical implant.
Further, the joint prosthesis forged using production technology of the present invention is directly used in clinic.
Joint prosthesis production technology can be divided into two types, and one kind is cast moulding, and one kind is forging type.At present it is generally accepted that
Cast moulding joint prosthesis is compared with forging type joint prosthesis, and the crystallite dimension of cast moulding joint prosthesis is thick, and uneven,
Consistency is also poor；Therefore forging type joint prosthesis is the preferred technique for producing high-quality joint prosthesis.
But the process of the production technology of traditional forging type joint prosthesis is that comparison is more, detailed process is：Cast first
Big steel ingot is produced, large steel ingot cogging, rolling, drawing are then turned into the thin rod of certain diameter again, then again thin rod is cut into
Segment, then carries out gathering stock by the thin rod of segment again, and local bend of the thin rod jumping-up of segment then is made into forging type people again
The rough forging in work joint, then could take this blank away forging.Therefore rough forging is made and is accomplished by substantial amounts of highly energy-consuming
Process, moreover, cogging, rolling, drawing need it is multiple leave out the beginning and the end, waste substantial amounts of expensive joint prosthesis metal material.
If casting small steel ingot, although cogging, rolling, drawing and the amount left out the beginning and the end can be lacked, but the forging that small steel ingot is made
Blank again can be not big enough due to deflection, and make it that the crystallite dimension of rough forging is not tiny enough, and causes the crystalline substance of final products
Particle size is not tiny enough.Moreover, casting out big steel ingot, large steel ingot cogging, rolling, drawing are then turned into certain diameter again
Thin rod, is then cut into segment by thin rod again, the thin rod of segment then is carried out into gathering stock again, then again by the thin rod jumping-up of segment
The crystallite dimension for locally bending the rough forging that forging type joint prosthesis is made is although tiny, but stored energy is higher,
And be deformation texture type fine grained texture, there is very strong directionality, if this results in annealing temperature not enough, with regard to crystal grain group
Knit unstable, Mechanical Property Anisotropy, be exactly generally product intensity it is directional, such as, longitudinal intensity is very
Height, but horizontal intensity is not high.And if annealing temperature is too high, the crystal grain chi driven by stored energy will be caused
Modest ability is big, and declines intensity.
And novel production process of the present invention is then the rough forging for directly casting out crystallite dimension very fine uniform, this is used
The final products that blank forging goes out are not only that crystallite dimension is more tiny, and because the fine grain of its rough forging used belongs to
In the equi-axed crystal of equilibrium freezing, therefore the storage energy and texture direction of generation are not deformed, so metal structure is stable
's.In addition, compared with conventional forging process, this novel process is that direct cast blank is just taken away forging, therefore process is few, power consumption
Less, material saving.Highly note in addition with a bit, exactly this forging technology can be protected with the forging deformation amount of very little
Demonstrate,prove the very tiny grain structure of final products.Because its rough forging initial grain size is just very tiny；Due to fine grain casting
The solidification shrinkage made is diffusion-type, therefore metal structure also can be very fine and close after forging；So, due to can be with deflection
It is small, therefore just can be using intensity, hardness on Design of Chemical Composition very high alloy, this makes it possible to make the strong of final products
Degree, hardness are higher.And traditional handicraft need large steel ingot cogging, rolling, drawing big deflection to be like that from principle cannot
Using intensity, hardness on Design of Chemical Composition very high alloy.

(1) present invention process method is applicable not only to the production in metal artificial joint, while suitable for outside joint prosthesis
All metal mold medical implants and other non-medical implants forging type metallic article, component of machine, with potential
Application value；
(2) present invention process method directly carries out forging using fine grain casting manufacture rough forging, can make final
Intensity, the hardness of product are higher, wearability is good；
(3) compared with similar products, consumption of raw materials is few for present invention process method, and energy resource consumption is few, and product qualification rate is high, fits
For industrial production.
