Preferably, the layer of the second material is NiP layers, and is in particular the chemical NiP layers by chemical deposition to deposit.
The combination related to the description below is especially preferred：
- copper beryllium alloy, especially CuBe2Pb are as the first nonmagnetic material, and chemical NiP layers are as second material layer
5；
- adonic, especially Declafor orAs the first nonmagnetic material, chemistry
NiP layers are as second material layer 5；
- stainless steel, especially high gap stainless steel are as the first nonmagnetic material, and chemical NiP layers are as the second material
The bed of material 5.
Therefore, the exterior surface area of at least pivot part is hardened, i.e. the remainder of mandrel can keep not changing or almost
Do not change, without carrying out any great change to the mechanical performance of balance staff 1.This selective sclerosing of the pivot part 3 of balance staff 1
Make it possible to combine for example low to the sensitiveness in magnetic field and can reach the machine of extraordinary impact resistance in main stress area
The advantages of tool performance.
In order to improve the repellence of the layer of the second material, pivot spindle may include at least one to be deposited on the first material and
Adhesion sublayers between the layer of two materials.For example, especially in the case of pivot spindle is made of the high gap stainless steel,
The sublayer of gold and/or the sublayer of electronickelling can be provided below the layer of two materials.
The invention further relates to the method for manufacturing balance staff described above.The method of the present invention advantageously comprises following steps：
A) balance staff 1 is preferably formed by rod turning or any other anti-dandruff process for machining, the balance staff 1 is at each of which end
Include at least one pivot part 3 made of the first nonmagnetic material at portion, to limit its sensitiveness to magnetic field；And
B) at least the pivot part 3 the material of outside deposition second layer 5, second material be selected from include Ni with
NiP group, to improve the mechanical performance of pivot part, at least to obtain appropriate impact resistance in main stress area.
Preferably, in step b) depositing second material layer 5 with show between 0.5 μm to 10 μm, be preferably between 1 μm
To 5 μm, be more preferably between 1 μm to 2 μm of thickness.
Advantageously, the step b) of the layer 5 of depositing second material can be by selected from including PVD, CVD, ALD, plating and chemistry
Deposition and the preferably method of the group of chemical deposition are realized.
According to a particularly preferred embodiment, the second material is NiP, and by using secondary phosphorus the step of deposit NiP layers 5
The technique that hydrochlorate carries out chemical nickel deposition is realized.
In the various parameters for carrying out needing to consider in chemical nickel deposition using hypophosphites, for example deposit in phosphorous water
Flat, pH value, temperature or nickel-plating liquid composition are known to those skilled in the art.For example, refer to Y.Ben Amor's et al.
Publication：Chimique de nickel, synthese bibliographique, Mat é riaux＆
Techniques 102,101 (2014).However, it is desirable to explanation, preferably using have medium phosphorous horizontal (6-9%) or
The commercial baths of high level of phosphorus (9-12%).However, it is understood that be, it is possible to use the less plating solution of phosphorus content or pure nickel plating
Liquid.
When the second material is preferably has the NiP of medium phosphorus content or high phosphorus content, the method according to the invention may be used also
It is included in the heat treatment step c) that the layer 5 to the second material carried out after deposition step b) is carried out.This heat treatment can obtain
There must be the layer 5 of the second material of the hardness being preferably between 900HV to 1000HV.
Chemical nickel deposition process is particularly advantageous in that it can be obtained suitably in the case where occurring without peak effect
Deposition.Therefore it can be anticipated that the size of the pivot spindle through rod turning, to be wished after the layer of the second material is covered
Geometry.
Chemical nickel deposition process also has the advantages of being applied in bulk.
In order to strengthen the repellence of the layer of the second material, the method according to the invention may additionally include before deposition step b)
The step d) for applying at least one adhesion sublayers on the first material carried out.For example, especially pivot spindle by high gap not
In the case that rust steel is made, the sublayer of gold and/or the sublayer of electronickelling can be applied before chemical nickel deposition.
It may include according to the pivot spindle of the present invention by being handled only to pivot part applying step b) according to the present invention
Pivot part, or can be made up completely of the first nonmagnetic material, its outer surface can pass through the whole surface in pivot mandrel
Upper applying step b) and the layer entirely covered with the second material.
In known manner, pivot part 3 can be rolled or polished before or after deposition step b), so that pivot
Transfer part 3 reaches required size and final surface smoothness.
Combined according to the pivot spindle of the present invention low to magnetic sensitivity and at least in main stress area impact resistance
The advantages of excellent.Therefore, in the event of an impact, be not in the meter that can influence movement according to the pivot spindle of the present invention
When any mark or any serious damage.
The example below is set forth to the present invention, but not therefore limits its scope.
Pivot spindle manufactures in known manner made of HIS.Undressed mandrel has 600HV hardness.
The method according to the invention is handled these batches of pivot spindles, and the pivot spindle is covered with thickness etc.
In 1.5 μm of NiP layers, the NiP layers are obtained using hypophosphites by commercial chemical nickel-plating liquid.
There is 500HV hardness according to these pivot spindles of the present invention.
All pivot spindles are subjected to clock field identical standard impulse program.There is no the undressed heart of NiP layers
Axle marks, as shown in Figure 3.Keep constant according to the mandrel covered with NiP layers of the present invention, as shown in Figure 4.According to
The advantages of pivot spindle of the present invention combines and excellent impact resistance low to magnetic sensitivity.
