Portion is anchored into hole.
Among the above, the nanometer level microporous aperture of stainless steel part is 15~50nm, and depth is 100~1000nm, is had
It is above-mentioned it is this it is nanometer level microporous after, then with synthetic resin carry out anchoring engagement.
The preparation method of stainless steel part of the present invention and the composite shaped body of synthetic resin is as follows：
In the way of punch forming, CNC machinings, forging, casting etc., stainless steel part and synthetic resin are processed into
The shape to be engaged；And it is not particularly limited the surface roughness of stainless steel part.
Then, when being electrolysed above-mentioned machined part, suspention jig need to be used, although aluminium, stainless steel part, titanium etc. may be selected
Industrial materials, but thus use titanium in view of the expendable of jig.It, can not be continuous since the consumption of subsequent electrolytic engineering is quick
Use aluminium and stainless steel part.
Only then, it is the degreasing operation of machined stainless steel part part removal surface grease etc..Degreasing mode is not special
It is not to be defined in using interfacial agent, pickling, electrolytic degreasing etc., as long as selection can suitably remove the mode of surface grease i.e.
Can, and depending on the type of degreasing material, implement the degreasing operation of about 10 minutes degree；Implementation phase property is washed again after degreasing,
Remain on surface to prevent degreasing agent, avoids bringing degreaser into successive projects after degreasing.
Again using frerrous chloride as in the electrolyte of principal component, the product of degreasing is completed in electrolysis.Electrolysis mode then uses positive and negative
Pulse High Voltage (PR) is electrolysed (checker) mode.Cathode then uses carbon, although stainless steel part can also be used, because of electrolyte
Principal component be frerrous chloride, be easy nature or electrolysis when cause dissolve and improve exchange frequency.Moreover for economic face,
It is preferable using carbon cathode.
Above-mentioned electrolyte is using ferrous chloride aqueous solution as principal component, and concentration is preferred with 0.3Mol/L~3Mol/L ranges,

The passivating film of titanium jig can be destroyed, and high current is flowed from jig.This high current can not only be brought on generation roughening, pothole
Extreme influence, can also waste electric power for economic face.
The frequency is preferred with 0.5~7Hz, duty ratio (Duty) is preferred with 30%~95%.It, can be because when frequency is excessive
Chlorion and reduce coarsening time, and effective roughening and Porous can not be generated.In addition, when less than 0.3Hz, roughening can be extended
Time, and expand asperities and Porous, and influence the progress integrally dissolved.
The electrolytic processing time was preferred with 60 seconds~300 seconds.If being less than 60 seconds, positive voltage number will be reduced, speech is changed
Can reduce porous prime number, and intensity and stability is caused all to decline.In addition, electrolytic processing time is more than 300 seconds or more, not
The difference in intensity can thus occur, but economic loss is larger.
By washing, then 40 degree or so of aqueous solution of nitric acid being soaked in concentration 15%~45% after above-mentioned electrolysis processing
It is interior of about 1 minute, to implement Passivation Treatment.
Implement after Passivation Treatment by washing, and in implementing ultrasonic wave cleaning in the sink of 25~60 degree or so of room temperature, this
When then clean 30 seconds or more, impurity, the coal dust on surface are betided when being electrolysed with removal.Thereafter, then with pure water washed, then about
With 80 degree of temperature, by product drying about 10 minutes, to allow surface that drying is presented really.
