Specific embodiment
The present invention relates to the manufacture method of a kind of dentistry dental filling alloy, comprising: material mixing step, it mixes dentistry dental filling alloy material; Melting step, the material of mixing described in its melting; Casting mold step, it makes the material of melting have a shaped, and described dentistry dental filling alloy comprises copper, nickel, palladium, iron, aluminium, manganese.
In addition, also comprising: calendaring processes, the alloy calendering having a shaped through described casting mold step is thin panel-shaped by it; Cutting off step, the alloy of described thin panel-shaped is cut to required size by it.
In addition, described melting step melting 2～4 hours at 1000～1200 DEG C.
If it is to dentistry dental filling alloy manufacture method of the present invention in detail, then as follows. Fig. 1 is the artwork representing dentistry dental filling alloy manufacture method.
Dentistry dental filling alloy of the present invention is made up of copper, nickel, palladium, iron, aluminium and manganese.
In addition, the content of described dentistry dental filling alloy is than for as follows: relative to copper 70～80 weight part, nickel 3～5 weight part, palladium 3～4 weight part, iron 3～5 weight part, aluminium 7～10 weight part and manganese 4～5 weight part.
The copper of the present invention, nickel, palladium, iron, aluminium and manganese put into high frequency melting crucible oven with pulverulence, its content is than for as follows: relative to copper 70～80 weight part, nickel 3～5 weight part, palladium 3～4 weight part, iron 3～5 weight part, aluminium 7～10 weight part and manganese 4～5 weight part.
Seemingly, price is lower than gold, if less than 70 weight parts, then manufacturing expense rises, and the dentistry dental filling alloy color manufactured becomes white, if more than 80 weight parts, then color can turn red quality deliquescing for the color of copper and metallographic. When utilizing dentistry dental filling alloy to manufacture dentistry dental filling, mobility is good in the molten state for nickel, if nickel is less than 3 weight parts, then when utilizing the dentistry dental filling alloy manufactured to manufacture dentistry dental filling, mobility decline in the molten state, if more than 5 weight parts, then elasticity disappears.
When utilizing the dentistry dental filling alloy manufactured to manufacture dentistry dental filling, palladium makes fusing point rise, if less than 3 weight parts, then when utilizing the dentistry dental filling alloy manufactured to manufacture dentistry dental filling, there is following defect: fusing point declines thus is easy to boiling and overflows, and the dentistry dental filling manufactured becomes frangible. If more than 4 weight parts, then fusing point becomes high, it may also be useful to become effort when person uses. When utilizing dentistry dental filling alloy to manufacture dentistry dental filling, iron makes intensity increase, if less than 3 weight parts, then the weakened of dentistry dental filling, if more than 5 weight parts, then too hard, elasticity disappears. If aluminium is less than 7 weight parts, then dentistry dental filling alloy color cannot become golden yellow, if more than 10 weight parts, then color becomes white.Manganese makes evaporating point improve, if manganese is less than 4 weight parts, then evaporating point reduces and while seething with excitement, can produce the phenomenon burnt, if more than 5 weight parts, then frangible.
As mentioned above, it is necessary, drop into material in crucible oven through melting step, melting 2～4 hours at 1000～1200 DEG C. If temperature is less than the situation of 1000 DEG C, melting is insufficient, if more than 1200 DEG C, then produces superheating phenomenon, so that material composition changes. Further, if the fusion time was less than 2 hours, then melting is incomplete, if more than 4 hours, then because long-time melting, institute is so that material composition changes or manufacturing cost rises.
On the other hand, as mentioned above, it is necessary, through the alloy solution of melting step melting, by foundry processing, form a shaped, then to the mould inside cast fused solution of the metal material of a shaped. Described metal is made up of high temperature resistant metals such as tungsten, even if injecting fused solution, mould also can not melt or be out of shape. Usual mould is made up of upper and lower mould, and the mold slots because being made up of upper and lower mould tool is formed as pole shape, thus inject alloy solution hardening after manufacture pole shape.
The alloy of the pole shape become through described manufacture technics can through calendering technology.
As long as calendering technology is suitable for common common technology, if between making the pole made in front technique by up-down roller, then manufacture the thin panel of thickness.
Described panel is cut to required size, thus manufactures dental filling (denture) or corona. Mainly cut into the square cross section being formed as easy to use.
Therefore, the unusual effect of the manufacture method of the dentistry dental filling alloy of the present invention is to manufacture dentistry dental filling alloy, and its surface is dazzling golden yellow, and attractive in appearance, intensity is big, good springiness, compare cheap for manufacturing cost with gold with gold.
