Specific embodiment
In the following, the present invention is described in detail.
The present invention relates to can be in the degradability Mg mainly by developing corrosion at high speed in the water system environment of water intervention
Alloy, using degradability Mg alloy the degradability structural member and degradability structural member corrosion rate adjustment
Method.
Degradability Mg alloy, Al content of the present invention needs to reach 3.9 mass % or more, preferably 7.0 matter
Measure % or more.Above-mentioned degradability Mg alloy obtains the effect for improving intensity by the addition of Al, but if less than 3.9 matter
% is measured, then said effect can become inadequate.If intensity is insufficient, the durability under hyperbaric environment is become inadequate, portion
A possibility that degradation speed adjusted that part is stated afterwards damages before being degraded will increase.On the other hand, the content of Al
Need to be set as 14.0 mass % hereinafter, preferably 13.0 mass % or less.This is because not only toughness (is stretched if Al is excessive
Long rate) it reduces, the deformation of creep also is easily caused under high temperature environment and is likely to result in strength reduction, if it exceeds 14.0 matter
Measure %, it is likely that be difficult to the shape of maintaining member.
Degradability Mg alloy, Mn content of the present invention needs to reach 0.1 mass % or more.Mn has conduct
Impurity and effect that a part of element for containing removes, if very few, the corrosion rate of above-mentioned degradability Mg alloy can be substantially
Deviate and be adjusted resulting value using aftermentioned Ni and Cu, so that control is possible to become inadequate.On the other hand, Mn
Content need to be set as 0.6 mass % hereinafter, preferably 0.5 mass % or less.This is because if excessive, Mn and Al's
Intermetallic compound and Mn monomer are largely precipitated and become fragile, so as to cause strength reduction.
Degradability Mg alloy of the present invention can contain 1.0 mass % Zn below.Zn, which can be obtained, improves intensity (spy
Not yield strength) effect.If it exceeds 1.0 mass %, then ductility becomes inadequate, and not only extrusion process, forging add
The moulding process of the structural member of work etc becomes difficult, moreover, because the effect for inhibiting corrosion rate is shown, therefore for
It is preferred for not being for degradability structural member.On the other hand, Zn can not be contained, its content range can also be made to fall into conduct
The content range of aftermentioned inevitable impurity.
Degradability Mg alloy of the present invention needs to contain both elements containing Ni, Cu or simultaneously.Because containing rule
Quantitative Ni or Cu and arbitrarily corrosion rate of the alloy under water system environment can be adjusted.That is, can make by the drop
The degradability structural member of solution property Mg alloy manufacture (timing) at the time of not needing the component is degraded.Wherein, though Ni and Cu
Degradability is so both contributed to, but since its influence power is different, it is preferred in order to be adjusted to optimal corrosion rate
Content range is different.
In the case where degradability Mg alloy of the present invention contains Ni, the content of Ni need to reach 0.01 mass % with
On.Compared with Cu, influence of the Ni to corrosion rate is bigger, nonetheless, is also difficult to sufficiently obtain if it is less than 0.01 mass %
As effect needed for degradability Mg alloy.On the other hand, the content of Ni is preferably set to 7.0 mass % or less.Even if exceedingly
Corrosion rate will not be extremely improved containing Ni, and physical property becomes difficult to control.In addition, if Ni is excessive, from cost this
From the aspect of, burden also becomes excessive.

Quality % range below, then can relative to the content of Ni logarithm and to corrosion rate (mg/cm2/ day) carry out it is linear close
Seemingly.That is, the corrosion rate for the degradability structural member that can be manufactured according to the content of Ni and to the above-mentioned degradability Mg alloy of utilization
It is adjusted.It, can be accurately to until the degradability structure manufactured using above-mentioned degradability Mg alloy by utilizing the property
Making the time until component is disintegrated is set.In addition, becoming the state of the corrosion of the benchmark of above-mentioned corrosion rate here
Refer to：It degrades from original alloy BOB(beginning of block), is dissolved or dispersed in water solvent and is formed as one and disappears with described piece.
In the case where degradability Mg alloy of the present invention contains Cu, the content of Cu need to reach 1.0 mass % with
On.Compared with Ni, influence of the Cu to corrosion rate is smaller, if it is less than 1.0 mass %, then is difficult to sufficiently obtain as degradability
Effect needed for Mg alloy.On the other hand, preferably the content of Cu is set as 10.0 mass % or less.Exceedingly containing Cu not
Corrosion rate can be improved to heavens, and physical property becomes difficult to control.
Especially if the amount of the Cu contained by degradability Mg alloy of the present invention is in 1.5 mass % or more, 7.0
Quality % range below, then can relative to the content of Cu logarithm and to corrosion rate (mg/cm2/ day) carry out it is linear close
Seemingly.That is, the corrosion rate for the degradability structural member that can be manufactured according to the content of Cu and to the above-mentioned degradability Mg alloy of utilization
It is adjusted.It, can be accurately to until the degradability structure manufactured using above-mentioned degradability Mg alloy by utilizing the property
Making the time until component is disintegrated is set.Especially because compared with Ni and influence power is smaller, so as to corresponding
Ground is easy to carry out high-precision adjustment.
In addition, degradability Mg alloy of the present invention can also contain both ingredients of Ni and Cu simultaneously, pass through difference
Adjustment appropriate is carried out to their content and realizes optimal corrosion rate.Since influence power is different according to content,
It is preferred that utilizing the difference when being adjusted.For example, it is also possible to ensure enough corrosion using the stronger Ni of influence power on one side
Speed carries out finer micro-adjustment using the lesser Cu of influence power based on content on one side.
Degradability Mg alloy of the present invention can contain the element other than above-mentioned element as inevitable impurity.

Amount is both less than 0.2 mass %, more preferably less than 0.1 mass %.In above-mentioned element, particularly preferred Si, Li, In, Ca's is respective
Content less than 0.1 mass %, more preferably less than 0.05 mass %.In order to exclude in utilization above-mentioned Ni and Cu to corrosion rate
Uncertain element in need of consideration when being adjusted, for the arbitrary element as inevitable impurity, and preferably
More fewer, better, particularly preferably less than detectable limit.
Other than above-mentioned Al, Mn, Zn, Ni, Cu and inevitable impurity, degradability Mg alloy of the present invention
Also contain Mg.
It, can be to be set as the range of above-mentioned quality % and reach for degradability Mg alloy of the present invention
The mode of desired corrosion rate is deployed using the raw material containing above-mentioned element and by usual way.In addition, above-mentioned
Quality % not directed to raw material percentage, but for after allotment alloy, ands being cast, being sintered to raw material etc.
The percentage of manufactured degradability structural member.Wherein, it is especially manufactured in the degradability structural member to desired strength
In the case where, preferably squeezed (extrude), forging (forge) etc. processing, thus reduce the crystalline size of alloy structure and
Improve intensity.In the case where being cast to above-mentioned degradability Mg alloy, which reaches 100~200 μm or so,
But if miniaturizeing crystalline size to 10 μm or more 20 μm or less Zuo You, then by force by above-mentioned extruding, forging, extension etc.
Degree is improved, therefore is preferred embodiment.Even if implementing to miniaturize to crystalline size in this way, corrosion rate will not be significant
It changes, arbitrarily corrosion rate can be adjusted by the content of Ni and Cu.
Especially if Ni is in 0.01 mass % or more, 0.3 mass % restriction range below, Cu is in 1.5 mass %
The above 7.0 mass % restriction range below then can suitably make relative to the increase of the logarithm of the content of Ni and Cu
The raising for obtaining corrosion rate is approximate to linear function.It can use the property and reduce Al, Mn and inevitable as much as possible
Impurity content fluctuation, correspond to the degradability Mg alloy of above-mentioned restriction range to the content of Ni or Cu for multiple spot
Corrosion rate is determined, and is calculated the slope and intercept of the corrosion rate of the logarithm of the content relative to Ni or Cu, is found out
The content of Ni or Cu corresponding with obtained corrosion rate thereby determines that the degradability structural member for being suitable for wanting manufacture
The composition of degradability Mg alloy.In addition, the common side such as least square method can be used when calculating slope and intercept
Method.In addition, linear approximation to a certain degree is able to carry out being less than above-mentioned restriction range, but if the amount of Ni, Cu are very few,
It is then difficult to accurately be adjusted actual content.On the other hand, if it exceeds above-mentioned restriction range, then can not ignore phase
Influence for the deviation of linear function.
For degradability structural member of the present invention, if first passing through the methods of extrusion process in advance applies pressure
And reduce crystal grain diameter, then compared with by casting manufactured structure, the coefficient (above-mentioned slope) that corrosion rate increases becomes smaller,
To become easier to carry out the adjustment of corrosion rate.
As the product for the degradability structural member that application is made of degradability Mg alloy of the present invention, such as can lift
The excavation apparatus of producing well, Gas Wells etc..In order to be introduced to underground dearly, it would be desirable to be able to bear the intensity of hyperbaric environment.Separately
On the one hand, if you do not need to the component is then not necessarily to the working hour being drawn off from deep under ground, work is being excavated by being exposed to
The aqueous solution introduced when industry can be degraded and corroding it at the time of appropriate, and thus, it is possible to remove the component.
