Abstract
The invention discloses a kind of antimicrobial form cochromes, by weight percentage include following chemical component: Cr 26~27.8%, Mo 5~8%, W 3~3.8%, Mn 3.6~4.2%, Si 2.5~3.5%, Ag 3~3.6%, Cu 0.5~1.8%, Ti 0.3~0.6%, compound rare-earth element 0.2~0.5%, surplus Co.The present invention is by adding suitable Ag and Cu and adjusting the content of other chemical components to assign its good spectrum antibacterial performance on the basis of guaranteeing the cochrome good mechanical property, the binding force of itself and porcelain body is effectively increased in the form of further improving the microstructure of the cochrome by the incorporation of compound rare-earth element simultaneously.
Description
Technical field
The present invention relates to dental material field, in particular to a kind of cochrome.
Background technique
Cobalt chromium porcelain alloy is applied to transplantation medical earliest, is used as hip joint and is used.Due to being traditionally used for baking-ceramic tooth
Ni-cr porcelain alloy have the defects that Ni harm and nickel-base alloy corrosion resistance it is not good enough, and cobalt chromium porcelain alloy contain it is more
Chromium, fusing point is higher, exists between alloy and investment and centainly reacts, gradually replaces ni-cr porcelain alloy.In the prior art
Has the report for improving to cochrome material and being adapted to artificial tooth, as invention patent publication number is CN1827814A
" a kind of dental ceramic stent cochrome containing rare earth La " and invention patent publication number are the " dentistry of CN102002613A
With cobalt chromium porcelain alloy material ".Although above-mentioned patent application is studied and has been reported to this kind of material, compared with the prior art
There is certain improvement.But it has been proved by practice that its preparation material the mechanical property that its specification is claimed cannot be fully achieved, and
And be still further improved with the binding force of porcelain, in addition, the alloy material of above-mentioned patent report does not have anti-microbial property, and
It is well known that it is vital for having good anti-microbial property for artificial tooth material.
Summary of the invention
It is an object of the invention in view of the above shortcomings of the prior art, provide a kind of antimicrobial form cochrome, mention simultaneously
For the preparation method of the cochrome.
The technical solution used in the present invention is: a kind of antimicrobial form cochrome, includes as follows by weight percentage

~3.6%, Cu 0.5~1.8%, Ti 0.3~0.6%, compound rare-earth element 0.2~0.5%, surplus Co.
As a further improvement of the foregoing solution, the chemical component of the compound rare-earth element is made of Ce, Re and La.Into
One step, the ratio of Ce, Re and La by weight percentage in the compound rare-earth element chemical component is 1:1:1.Specifically,
The particular determination of heretofore described compound rare-earth element has superior cochrome microcosmic compared with Rare Earth Elements Determination incorporation
Form improvement, to substantially increase the binding force of itself and porcelain body.
A kind of preparation method of antimicrobial form cochrome as described above comprising following technique: by each chemical component
Ingredient is put into high-temperature ceramic copple, is stirred 3~8s after vacuum intermediate-frequency or the fusing of high frequency stove heating, is then cast into mold,
It is to be cooled at ingot bar rear surface blasting treatment, obtain finished product.
The beneficial effects of the present invention are: the present invention is by adding suitable Ag and Cu and adjusting the content of other chemical components
To assign its good spectrum antibacterial performance on the basis of guaranteeing the cochrome good mechanical property, while by multiple
The incorporation of rare-earth elements effectively increases the knot of itself and porcelain body in the form of further improving the microstructure of the cochrome
With joint efforts.
